21. My Cheap Ferrari 308 Throws Another Fit - Featuring Iain Tyrrell

[Laughter] see when you're a true pro when that car is right you're going to be very happy with it trust me when i took that out much to my horror um i saw there's a load of white gunk in it which is a bit like you know the mayonnaise you find in engine blocks when there's water in the block well everybody i'm not gonna lie it's been a totally disastrous couple of days so far [Music] hello everybody welcome i'm jack and this is the influenza and all i want to say is it's worth watching this whole video because it's possibly one of the most significant that i have in terms of the influenza and unfortunately things do not end well i've got the carbs out of the influenza i haven't bothered videoing all that because i think it's just it's just boring seeing someone tinkering over an engine bay but they are here they're spread all over the garage on top of that bench here and here um i've taken them mostly apart there's still some bits to go i've been dipping them in this cleaning solution and we're going to be speaking to ian tyrell in a moment because i have some questions for him he's going to be doing final setup on the influenza once these are rebuilt hi ian really good to talk to you pleasure pleasure no problem here is the the beast in essence i've had a bit of an adventure with it i guess my first question is i've had a look and they come with the standard jets which are 50 idols and 130 mains is it worth me looking at some different jetting options or should we just stick with these you're doing this is quite timely because things they are changing with petrol you know we live in the age of e5 and we've had a couple of dinos in recently um very similar of course but just two cylinders less and we found that we've actually had to reject the carbs just to get them back to running normally again and you mentioned the 50 idle jets with more than one car we've had in we've had to put them up to 55 just to stop sort of fluffiness and flat spots low down and things like that i mean that car would have been running on five-star fuel when it was new um which was 100 octane leaded thank you very much and obviously things are different now um i would suggest as i say i think you ought to uh to put the just as a matter of course put the idol jets up to 55s and with regards to the mains should we just stick with the 130s or should i say yeah there's two other things i would mention to you actually yep one is the floats i'm assuming the float to the original soldered two piece brass ones are they correct yeah okay um unfortunately i think the best will in the world you can consign those to back to the shelf again yeah what i would suggest you do is buy uh four new floats again from webcon and they're made of a material called spansil the brush floats what happens is ethanol in the petrol eats away at the solder that holds the two brass floats halves together and when they fill with petrol that's very bad news because obviously the float chamber fills up acts like a tank it overflows and you've got a fire hazard and the engine starts to run abysmally so the second thing is we had spoken briefly about getting the bodies ultrasonically cleaned and the reason why i've gone slightly against the ultrasonic cleaning is that i remember when i've taken these apart before that this butterfly can be a real pain depending on those screws and the bearings seem fine so disturbing it all just seems a little bit pointless to me so my only worry with these is that they will they will have air leaks that will go through but if i pack them with the grease and then reassemble them all certainly for a fair amount of time i presume they will be airtight do you think that's sufficient or should i order the new style bearings take everything apart and do it that way because they're so beautifully engineered with those bearings in them as opposed to just relying on a bronze bush for the throttle spindle they don't wear tremendously um so i would be inclined to leave them be you the chances of you getting an air leak through the throttle spindle are very very small i mean you've worked on some fairly impressive cars obviously there was um fructose contact and so on but i i presume that working on the influenza will be a career defining moment for you you must be quite excited well it's a great engine that ferrari v8 is a great engine i haven't warmed to this engine that much and i think part the reason is it's still not running properly and hence i'm rebuilding the carbs to take that out of the equation but having seen them i don't think that's the issue it works very very well up until 5000 rpm which is where i believe these engines should really take off and that is where this one just sort of just meanders up it will rev but without any gusto but what do you think the reasons for that could be that it's that it's still doing that what are the most obvious culprits two things spring to mind and i've come across both of them over the years so these are things that i sort of know about or have come across and number one is is the advanced curve right in the distributor uh the centrifugal advance is crucial actually and if the the centrifugal advance obviously has bought two spring-loaded bob weights inside the distributor which advanced the timing you really may need to make sure that the springs the pivots the bob weights all that are free all of which can throw the timing of the centrifugal advance curve out so it's worth revisiting that if you haven't done already the second thing i've come across is it's a full cam v8 obviously it's got two cam belts one for each bank because obviously originally ferrari recommended you change the belts on that engine once every two years which is a bit crazy really and then ferrari relented and said oh no let's make it three about 20 years ago or something and the reason i actually had a word with somebody in their technical department at marinello concessionaires about this years ago i'm drifting off peace slightly here and the reason he came up with are you ready for this yeah why the belts needed changing even if you'd been nowhere in the car or not was because he said ozone emanated from the alternator windings and it degraded the rubber in the belt there you go unbelievable that's the technical reason or it was yeah um so but what i was going to say was quite often i found when i've pulled the the covers off the cam belt uh sprockets that there are about three or four different painted marks from people over the years who dabbed paint here and there thinking that they're lining the cams up etc there should be a more positive register than that and it's it's where i'm going with this is it's quite possible one of the banks uh has got the valve timing maybe out of tooth or something like that i mean if that was the case though wouldn't it be even more obvious wouldn't it be running really badly everywhere no i had it on a 308 gtbi years ago and same engine essentially different cam profiles and different valve timing but similar to yours and um it again it just had no poke at the top end at all it would idle smoothly it would pull cleanly at low revs to medium revs after tearing my hair out with just about everything imaginable pulled the um the timing belt covers off and discovered that i think one cam was either one or two teeth out on one bank and i put it back together i mean seriously that engine particularly with the cart with that early carb setup it should be happening at five thousand five thousand five hundred rpm between there and the red line at seven seven that thing should go like it's on laughing gas yeah really good if we can check all this if you're happy to do that when i bring it out that's awesome i can just concentrate on the carbs when that car is right you're going to be very happy with it trust me wow that's going really well brilliant thank you so in the assembly first of all we will start with some of the interesting stuff right so we have the assembled main jet here probably in this car from about 2000 revs upwards this governs the speed of the car and the fueling of the car now these venturis they're called that you can see here they have a little hole going through there they go at the top of the carb here cob goes like that air goes through as it goes through it sucks through this venturi causing a vacuum that's where the manger is okay so the venturi's in the main is in and we just screw that down you also have where are they these are the idle jets so this is where the idle circuit goes and where the idle jets go they've got new o-rings and one of these idle jets was what was causing all the problems of the car only running on seven cylinders so all of these have been cleaned dipped overnight and then blown through with carb cleaner as well so it should all be pretty much as good as new this is another jet this is actually the jet for sometimes when you accelerate when you try and accelerate quickly and you open the butterflies there's a delay in which the carb can't quite respond quick enough to that what weber did which is really clever they have this device called the accelerator pump which just squirts a bit of fuel in as you open the butterflies and gives the vacuum a chance to catch up so the car isn't running quickly enough there's not enough air going through to suck the fuel that's needed for that quick burst of acceleration that is the accelerator jet and the way it works this is essentially a little rubber diaphragm again this is a new part that comes with a rebuild kit and this is the part of the accelerator pump which i think is really it's just ingenious really you have a little lever there so what happens is that when you turn the when you accelerate if you accelerate hard enough you will cause this diaphragm you see there's a little ramp there to be pushed when that is pushed up anyway when it's pushed up that diaphragm compresses and pushes a load of fuel that gets squirted into those alleys i can hopefully show you a little picture of that uh a video of that from when they were doing it before but that's the other ingenious thing i won't go into more detail on that i think that's probably enough for now the tops of the carbs also had to have some work done to them so i've had to measure the the clearances for the floats make sure they had the amount the right amount of trouble because that adjusts how much fuel is in the bowls which can have quite a dramatic effect on the fueling in the engine i've also replaced these little needle valves which switch the fuel on and off depending on the height of the float and clean them up and done some other bits with these pipes i haven't bothered doing anything just replace the gaskets on there but essentially it all fits in like this and i'm not gonna bother screwing it all in together at the moment because to go in the car it's easier to put them in without the tops and to put in the tops afterwards but essentially they are pretty much ready to go the the valves for the idle speed or the idle speed screws rather they have been cleaned the seats have been cleaned and they are there the choke mechanism is in place and the air bleed screws which you use to adjust and balance the two different circuits within the carbs at idle those are in as well they've all been cleaned so we're practically ready to go i thought i would renew some of the pipes because they look a bit tired and i had a really nasty shock uh when i took them out i found all this white sludge inside pipe that connects up the the two banks of the engine so i thought well i better renew the you know the the the rubber unions on that because they look quite perished yeah aluminium pipe just joins their heads and um it goes down to a little canister and stuff so i think it's a little sort of vent when i took that out much to my horror um i saw there's a load of white gunk in it which is a bit like you know the mayonnaise you find in engine blocks when there's water in the block uh and also when i took the pipe off some water actually came out of it and so i'm sort of slightly panicking is this a definite sign something's off or do they connect oh great it's rushed you know for the last of its life yeah and quite possibly it's just built up vapors and things in there clean this out put it back on and uh i think you'll be all right and keep an eye on it oh that's a real relief here thank you so much great all right have a good christmas you too okay thanks ian see ya bye bye that has shortened my life by uh by a year that that was just uh i was convinced when there was like that that sort of mayonnaise in that breather that i was like that's the end of the engine but once again it's confounded my expectations and they do do that and there was condensation in it as you can see as well so i think that's all that's happened maybe that canister is also blocked so i'm gonna give it a clean but right so the carbs are rebuilt i've fitted them i've replaced the fuel lines all the various other bits and now it's time to see if it will start um [Music] i don't know maybe i shouldn't be surprised but i kind of am that it seems to be running so well and it does feel even just i just maneuvered it in because to tune the cubs and stuff i have to do it the other side because this points towards the back of the garage and i get gassed but started much easier than i thought and it seems to be running a lot better than i did i was expecting as well so so far like it's all pretty good news i'm i'm pretty shocked really but um i shouldn't say stuff like that because something will happen any second um but so far it's looking good well it's another day everyone and unfortunately things haven't gone quite to plan which is a massive shocker so today was supposed to be the triumphant day where i was going to go out in the car filming the car talking about it running with the new carbs and what a great job i'd done and everything else and my optimism has quite rightly been slapped down the influenza has taught me another lesson and that is don't count your your chickens before the eggs hatch don't count your eggs before the whatever it is i don't know well everybody i'm not gonna lie it's been a totally disastrous couple of days so far so it all started with this issue i had that i couldn't keep the revs down so the engine will rev up but then it won't drop or it will drop very very slowly and then it won't go right to tick over i checked a lot of things i thought it was the throttle linkage i thought it was all that kind of stuff but i've been on that phone with les as well the wizard from up north who helped me a lot in the past who rebuilt his gt4 and knows these really well and we kept on sort of you know we disconnected both banks of carbs i tried to do them independently and still even when they're not connected and you rev it the rev stick it's very odd but i thought it had to be something i'd done to the carbs anyway it got to the stage where if the revs go up if you you can bring them down with a clutch i.e just put some pressure on the engine brings the revs down if you let it go they don't go back up it's not the linkage i then had a look les was talking me through a few things and i had a look at the distributor which has adjusted all the way up which isn't right it should be somewhere in the middle so the timing although it's right is completely wrong if you know what i mean what that all points to is that one bank is probably out a tooth on the belt and then it's mis-timed and that's why the timing has been moved so much from the distributor to get it to idle properly but even worse than that is i took off that pipe that breather pipe between the engine the two halves of the engine and much to my horror there was way too much condensation on water in there it's all now pointing to water getting into the into the oil doesn't look like it's a head gasket because essentially the head gasket if it was a head gasket i'd be getting trouble with the car running there'd be smoke there's none of that and there weren't any hydrocarbons in the water tank but i think there is a coolant or water getting into the engine and then it's not a lot what happens is it condenses comes up into that pipe i don't know i honestly i just don't know every time i think i know something about this it turns out not to be true uh i can't be sure i'm gonna have to do some more testing i want to get it to run right anyway because there's this issue with the timing which is definitely not right i don't think i'm going to wait to bring it up to ian to check the timing i think i'm going to try and check that myself initially just to see where i am i mean i understand everything points towards the carbs i've rebuilt them it's something to do with the carbs but i really don't think it is i think what happened is before with the carbs so old and dirty and well-adjusted it probably wasn't running very efficiently and so especially on idle and so the revs would would drop would drop back even with it advanced with the wrong advance or the way it is has to be advanced to run at the moment but this all ties in as well with my issue that i have that it just doesn't run well at the top end ian also said look i think it's a timing issue either with the belts or whatever anyway it's really you know the bell issue isn't such a bad thing obviously if that turns out to be good and you know the car starts to run better at top end that's brilliant but this water issue constant that's just been me with me throughout the car and i always think that something's going on and then it isn't that is much more of a gigantic thing and again it's pointing towards a full rebuild so sorry to end on such a low and uh yeah i'm feeling a bit sorry for myself but thank you everybody and um see you for the for the next video hopefully i don't know i'll get some clarity on what's going on with the car by then we'll see just realized by the way i wasn't wearing a belt totally unintentional because i'm filming as well i put a camera on and then i forgot to put the belt back on anyway see you everybody thank you very much please do follow me follow the adventure on my instagram and please do subscribe thank you all very much see you soon
