Ford F-150 5.4L 3v Triton Engines: This is Why You Always Replace the Roller Followers!

hey guys what's up welcome back to the shop once again so today i have a 2005 ford f-150 543 valve of course they had a trailer transported in from california for me to take a look at it so the problem with this truck is that they just supposedly had a timing job 20 000 miles ago using ford parts and you go and start this thing up and it's a horrible rattle noise going on this thing and it's constantly there while the engine's running too i'm thinking it's mainly from this side right here and everything's basically new inside of there so i'm thinking something didn't get put back together right or they didn't replace followers and they're failed or something like that so let's take a listen let's go ahead and start it up [Music] [Music] i'm not sure what's going on fans obviously loud but man this does not sound good it sounds like it is from uh the valtrye on top once it calms down take a listen the loud tapping noise on startup and it's constantly there afterwards definitely on the passenger side i'm not really hearing it over here i'm hearing it coming through from the passenger side so what i'm going to do is some quick diagnostics to verify with my stethoscope to see what side it's on what cylinder is located above and then we're going to tear it down once i have torn down on there i'll let you guys come back and we'll check it out together let's see what's going on and make all this noise all right here we go the big reveal so i have not taken a peek yet um i have not pulled it off in any way so we're gonna pull together and see what's going on inside there i'm thinking it's something the roller flower or lash adjuster hopefully that's it something simple look how nice and clean everything is in here these bolts look like they're brand new a little bit of dirt on them and that's it this tech's out in california and southern states they got it made and that's an old five and it looks like this had had a car the other day i was doing spark plugs on it and everything's just rotted big time on it painting anything off these vehicles are getting older now okay so she looks absolutely beautiful the guy took care of the oil obviously uh let me see looks like a ford solenoid there which is good looks like ford phasers i don't see marks on the phaser indicating they did a torque to yield uh sequence on there but okay so again we're going after the valve train on here so anytime i have a concern like this first thing i do is a visual inspection or any of the cam lobes damaged everything looks good so far okay the next thing i'll do is i'll physically grab the followers all the way along see this one it's moving all right so the cantaloupe looks okay i'm looking closer later um but that one's moving that has failed so i'm just grabbing them i'm grabbing onto them with my fingers on both sides and then i grab them and i try to move them all right they should be nice and solid in there whether they're being actuated by the cam lobe or not they should be pretty solid looks good this one's got a little bit to it so everything over here looks good even the cam lobes well this is the base circle of this lobe right here let's see if they got camshafts the camshafts for the earlier vehicles i think all 405 before they change the profile they're like a three four hundred dollars uh whereas the newer ones oh i would say 08 mid-year and newer maybe 10 and newer not sure the date break those ones like 115 but the older stuff becoming really expensive the valve cover gaskets for these older vehicles ea and db there's sixty dollars my cost yeah crazy prices for these older pieces on here so what i'll do is i'll bring it closer look at it so everything on here looks good to go good i'll check chem cap torque as i'm pulling them off when i go to repair this but they look fine too i don't see anything loose with the cam caps on here uh so only i see so far is the intake for cylinder number four so this one i'll show you guys now it's a side note here roller follower failures are common enough across the board on the 543 valve and 463 valve all right so anytime you're in here doing a timing job you want to replace it no matter what there is a revised design now with a smaller hole in it for better oiling on there but for also a more let's say less bleed out more back pressure in the oil system the oil log built into the head to feed the rest of the vct system all right so there's multiple reasons why you want to change the roller followers no matter what and uh oh nine and newer they fail constantly especially uh three and seven all right uh whereas this generation they usually don't fail too often but they can as you'll see here so this is the older style and you can tell by the oiling hole see how big that hole is on there the new one is about the size of a pin tip yeah so these are definitely original they should have changed them while they were in here so we're looking along and like i said you want to grab them and move them see i can move it a little bit this one's basically on uh base circle so you can move it a little bit now i'm gonna be actuator like this one right here is being actually you see it the nose of the cam is actually touching the roller follower i can't move it at all there's no lash in there which is the way it should be so we'll go back here and we'll show you let me get to better light for you guys let me see yeah that's probably pretty good so back here and i'll just zoom you guys in so here's cylinder number four all right uh so you can see this side of the cantaloupe is just fine but you look down in there and you can see the uh the roller part of the follower has failed so when they fail they they kind of come apart and the thing either seizes up or starts to fall in there you lose your profile and then there's all this lash in here and that's what makes that crazy noise and of course since the follower itself failed nothing is going to fix that it will constantly tap from cold to hot so the other thing i look for because i'll chew them up on the nose usually when they're actuating which is this side let me see on this side right here the nose is where it'll chew it up when it's actuating it because that's what actually has full contact and pressure on that roller part of the follower so you'll see the nose here so you know you probably send that down um but you're taking a chance of it ruining another follower on there so you move it from the back side here you can see that's all it was so i can feel the last just on this side's fine and of course the spring is fine you can see it looks beautiful he took care of the oil in here i mean look at it we just have a follower failure we should probably change his camshaft on here very very simple and this whole thing this whole cost of basically transporting it out to me and my fix now retroactively after the fact of the follower and probably camshaft and of course you gotta change the phaser bolt at least he could have avoided all that just by if that shop would have gone the extra mile and changed the roller followers you always always do that one of these days i'm gonna get together a bulletproof video and put all these tips together i should do that soon um but i'm telling you now this is why just the exact reason why okay so we did get the go ahead from the customer to not only change out this side's camshaft and followers but he said you know what while you're in there we know this side has the old style components in it let's go ahead and pull apart the driver's side and replace that too so everything is all new like i said he just had timing job 20 000 miles ago all four components and you're good to go they just neglected to change the followers out so here on the on the passenger side i had the camshaft in new roller followers all that good stuff we reused the phaser on here because it was a new ford one um and of course replace the torque to yield phaser bolt on there got that all torqued down on there and everything in here is torqued down and cleaned up and good to go and now we're starting on this side so this is what i found in there and this is really common like i said usually an 09 and newer so this is the old uh follower that failed you can see it's chewed up pretty bad on the outside there that's where it was actually grinding into the cam lobe on there chewing it up all right and then of course this is locked up so that was chewing into us at a to a point also but it really it mainly just dropped so look at the side reveal i see that's hanging down way down in there and up top here it's way low it's sub flush well by contrast here's a brand new roller follower you can see the reveal up top there a little bit right and then down below if you look at directly from the side it really doesn't hang down below that's how they should be and you look at this one yeah you can see so it's hanging way down and that's when we're getting all that lash and all that noise over there and of course just starts chewing in the camshaft so this new style you can see it has a really small oiling hole in there look how small it is it's like a pin prick tip it's it that's that's about how big it is i mean it's just it's very small uh compared to this one this one right there you can see right through the blue towel in the back there see it that's a huge hole so with all of these you got 12 on each side down to this size right here and this is the angle a bit more to actually hit the follower directly on it they actually increase the back pressure in the oil log in the head so that there's more pressure and volume reserved in the oil log for the vct system on here so that's going to help with that too so there's multiple reasons why you want to change those followers not just because they fail all the time so the way i do these when i'm changing a camshaft out like this you're basically pulling everything apart up top here so what i'll do is i'll do the same thing uh same method use the same method we use for changing out phasers in vehicle you bust out the old cheese wedge you wedge the chain and i have videos detailing all of this you wedge a chain so you don't lose time down below the crank and then you can go ahead and start loosening your cam caps on here and get your cam shaft and phaser out i pull them out together makes it easier that way before you do that though you better mark your relation of the chain to the phasers so we have it marked really well here you see there's lots of paint on there don't want to lose that marking so what i do on the phaser when i'm pulling i'll look at i'll see what is exposed currently and this one it was the r so the r is a known point and so is the l on here it's a known point in the phaser it's very easy to identify quick to identify whichever ones touching the chain you have access to that's the one i'll mark so i know the r goes right back with that that paint mark on the chain and we're good to go we're back in time top here and that wedge is holding time down below all right let me show you if i can get the maybe this one right here yeah there it is right here it's actually contacting and chewing into it that's the nose of it so this one's not so bad but they can get really bad either way once they get they get grooved like this i know it's hard to see and then rough here in the center it's just going to chew up the new follower so you want to change out the camshaft so this one basically sunk and then it froze up and kind of got out of the way once it was rubbing on it for a while here that's why the damage is not so bad so yeah like what i said i like i'll i'll go ahead and i'll go ahead and transfer the phaser a new bolt to the new camshaft and then we'll go ahead and just lay it back in there the same way as if you were laying in a new uh phaser in vehicle you know while it's apart though it's a great time to look around make sure no valve springs are broken it's not too common on the 543 valve lash adjusters they're they're not too common either but something you want to check you know so we what i do is i just press on them all the way along just kind of feel for them press them they should give a very very small amount but otherwise be rock hard all right take a look at the wear on the cam towers here if it looks good like i said this guy was maintaining the oils everything else is good in here so we're gonna go ahead and put new followers on this side and of course the new camshaft and reuse the phaser same thing as the other side and they'll make this timing job more complete you know the way they should have done in the first place so i'm gonna get this all back together so i can get out of here and tomorrow once the sealant dries uh i'll go ahead and fire it and let you guys hear the difference by putting the new parts in there so i stayed late last night got it all back together so everything's good to go now and dry sealant's all cured on there let's go ahead and try it out see if this thing sounds like new oh yeah oh sounds good so far looks like a brand new 543 valve on both sides nice and smooth nice and quiet so that's it for now guys i just want to show you how how important it is to change your followers whenever you're inside of there doing anything you want to put the latest and greatest ford followers in there i need to go ahead and get on to the water pump job on that edge over there i'm gonna crank the ac back here and close my doors and get to it that's all for now guys i'll see you later you
