you're on the policeman for on youtube channel are we getting a cart yeah it's like we need a cart looking for the flex seal on the other side all right thank you hmm just what we needed to see there's a lot of different types i just kind of wasn't expecting this likes tape you can double up you know what i think we're gonna need some help i don't know which one's rated for the most temperature hey i'm a local scientist i'm a local scientist and i was wondering if you could help me with some paint i will in a few minutes so okay what are we working with here yeah can you help us i try perfect you got any experience using this stuff with a head gasket for like a vehicle we need to know what the highest rated temperature flex seal available is with a head gasket yes what kind of temperature i mean you don't know this stuff off top of your head i'm gonna go google and that's what i'm gonna do unbelievable crystal clear instant grab and hold works under water that's not a bad i mean that could go good with the water in the water 80 to 350 negative 80 degrees to 350 degrees fahrenheit oh that's for the original you might want to use like the tube stuff because it's more like gonna be like your gasket material for like the gasket stuff oh you're thinking flex paste that's kind of where i'm thinking i don't know how well it's gonna hold up seals out the elements fills large gaps and holes apply on wet or dry this might be the dry time on that puppy 24 hours yeah but are we really using flex seal this is flex paste it's flex seal video basically silicone we know that works [Applause] how many of these we need george we need og flex seal anything just one no probably like at least like 12 or 13 probably just yeah thank you jeffrey that'll be all have a good one dude what a great guy dude down here helping us no turning back we got to buy them all i was just kind of doing it as a stunt but did you see how much they are again both of them walked up on us i know did you see how well they're 13. i'll go hide those what jeffrey jeffrey are you serious dude you didn't tell us about the flex seal max down here see i don't know anything about the flex seal max one just a different can guys don't be fooled by the marketing hey i asked you first no you disappeared i said i didn't no jeffrey came to my house dude i mean but i am this local scientist i said okay i got a customer ahead of you well what do you can you tell me more i need to know the temperatures that flex seal is good for i'm i'm building the head gasket out of it jeffrey said it'll hold a thousand horsepower and tell jungkook how i come from arabia how many camels is that how many camel powers it's been a wonderful experience you know what i'm never going to home depot again do you think you think we got enough george just barely i just barely enough all right dude it's like a doctor either last week dude that's a special live joke yeah oh it's a chef coke oh no one button then just no you don't have to when it's a 4x you just slaughter over there looks like a little kid now we're just cleaning up this motor for this thumbnail but this is actually a good representation of how james works on his own cars all right guys so since this is a science channel we got to teach something if you didn't know a head gasket goes on the deck of the engine and then the cylinder head which is one of these right here goes on top of this and sandwiches it to the block and the job the head gasket is to keep the pressure that's inside the cylinder from escaping so if that air escapes you'll get into your water jackets here and then when you get pressure in your coolant system that's when you know your head gas is bad usually for us it starts blowing water out the radiator cap or worse if you blow your head gas really bad it can blow pressure you know down through the bottom of the head and it can actually send like fire through here and torch your head put a big hole in it so the head gasket's really important especially when you run a really high amount of boost it's got to keep a lot of pressure inside that cylinder so we use a lot of different types of head gaskets and today we're going to ditch the metal head gaskets all together change it out for flex seal which is advertised too stop leaks fast this is a liquid rubber sealant coating and we're gonna try it out on george's blazer because the head gasket is bad so this is the cylinder head off the blazer right now we're gonna start coating this puppy up put a few coats on it it's kinda gotta be thick because if it's too thin the valves and pistons might say hi to each other you know so a normal head gasket has a little bit of thickness to it so we got to kind of put a few layers on there and then we're going to clamp it down fire it up see if it holds it's so so thick dude it's so thick don't make sure you get enough of it so your quench is right dude we're not gonna have to put that many layers on maybe two or three guys so they can handle more heat right oh dude this is on the road in a jiffy you probably leave it on the pistons it'll burn right off yeah i think you leave the overspray and it becomes a protective uh top coat for extra heat can really turn up your tuna then you're spraying on this crack piston look right right here guys we had a cracked piston where literally sealed it not cracked anymore spray some more in there it's not cracked anymore told you all right looks like we're going through with this project let's head over to the blazer all right guys so we kind of we're looking at this from a couple different angles we could spray the block or we could spray the cylinder head i mean what do you guys think fellow scientists i mean you only got two and a quarter piston down so i mean you could just coat her up wiper i mean i feel like we need to take them off at least the pistons you don't want to tape off not doing the kevlar flex seal coating you know we're testing theories here we're not just proving something this is a what's that h word this is a we got a hypothetical hypotenuse let's do one variable at a time and that's going to be the head gasket piston protection we can do another day nice job dr jt you really cut these clean you just slide them right in there we're doing one thick coat or multiple thin coats we'll do a couple two thin coats two medium coats two medium coats right oh oh you missed fire dude it is first big surgery sorry mine's a little different all right dude here we go should i start at the top start at the bottom you're the doctor i don't know good job that was that was a test oh dude this is gonna be guaranteed hopefully those threads are golden if this head gasket leaks i will just be amazed okay you're at medium for sure medium to moderate dude look at the texture oh i am feeling so good about this i don't know if i liked my strategy as much as i did right there it's okay just hold it further away i have less pressure [Music] dude that is gonna work so good one more one more yeah yeah do another one we've maybe used a third of this can it's a lot of flexibility [Music] dude thick coat of flex seal all right so now that we have trial number one set up and ready in the morning we're gonna go ahead and stick this cylinder head on the blazer ah scientists this is looking pretty good guys are flex seal teared up overnight situation it's not ideal there so now the plan is after thinking about it overnight what we're gonna do is throw one more coat of flex seal on here and while it's wet we're gonna go ahead and put the cylinder head on the engine tighten it down and then let it cure call it the seal coat that's the seal coat so we need to get uh get this ready i say we spray the block and then we pop this sucker on all right dr steady hands get the cylinder head ready we need one stick on this nice out of the way not a thick cut enough yeah let's thicken that up a notch all right here we go here we go the wet bonding going on all in there how are we looking can you look through the bowl hold on see look at that hammer might need a hammer oh watch the valves did not budge it was nice yeah it went down no problem doctor no mess around you scalpel all right okay yeah you're good to step it [Music] oh there ain't water it's working outside of the head yet is there not yet hey look yeah don't look just close your eyes all right guys we'll have the blazer running momentarily sam you think the head gasket's gonna gonna work perfect billy mays would be proud of it yeah he would here we go folks hopefully we won't hear you out the side of the head oh [Music] all right doesn't sound that bad guys hey it's actually working dude it's i think it's actually working the valve train's a little noisy but according to my calculations our hypotheses oh already a win for sure yeah there's not a lot of air pressure in here and it's holding what was in it so i mean right now the head gasket's definitely holding yeah it's sealed it'd be pouring out of here if it wasn't keep this pointed up so we know so we know so if this starts spraying water guys we know the head gas is compromised dr george why don't you pull her back there let's get a naturally aspirated hit across the parking lot yeah let's do just a first year hit off actually it's not that bad besides the [Music] horrible knocking sound [Applause] wow [Music] all right doctor spray and pray will you turn the nitrous on yeah it needs to be sprayed that's a true test i think it's still holding cold pressure because feel there's still oh wow yeah got a little expansion a little contraction just what flex seal does man let's spray some nitrous in this baby are you ready or what i'm ready dude what's your guesstimation she gonna hold the nitrous all right right chip [Music] does not sound great love that thing rip oh wait you got to spill it hit it again [Music] you definitely just blew the head gasket there she goes water came out the top of the head too oh my god broke off dude dude it just sprayed water out of every crevice it could have [Music] she still runs [Music] okay it's done back up back up yeah don't fan it don't fan it hit it there you go joker everybody safe everybody's good ladies and gentlemen what we've learned today on the cleese mcfarland science channel is that yes you can use play steel for your head gasket however with the addition of nitrous your flex seal may not pass the test we did a first gear pull no issues across the parking lot naturally aspirated however when we added in the nitrous it went ahead and blew the head gasket out of the entire engines flex seal does work but only up to about 300 horsepower is our guesstimations here today that's another video here on the cleese mcfarland science channel drop your ideas in the comments below thanks for watching see you later [Music] bye
