Not to question your tuning skills but,take some time to scan/log wot after you it get back together.Even with the gaskets being graphite it still takes a good bit of cylinder pressure to blow one out.Where are your coolant temps runin start to finish at wot?

 

That gasket has been on there the whole time this truck has been boosted, so its no surprise it went last night. I dump a shitload of meth in so I don't think it was just a one time event blowing the gasket out. I'm sure its been gradually happening over the past year. I am running 9.5:1 CR though... Coolant temps don't rise more than a few degrees. Nothing crazy.

 

Jus for refrence me and kyle blew stock graphite gaskets at 11-12#'s on 4.8's.Both did take a good bit of time/miles so you probably right on with it being mechanical failure.

 

Sorry to here that you blew head gasket.

 

Mine didn't actually blow, it would just push coolant over 10-11 psi. It was till running fine at 7psi when I pulled it out. I'm not sure what gaskets it actually has, it's all stock and still bolted together sitting in the corner of my shop.

 

Its probably because of Richard's old cursed injectors. Set of SD60s that are guaranteed to destroy any engine you put them on. lol

So just to throw this out there...is there any possibility that it broke something else when the gasket blew? Like getting water in that cylinder and increasing compression to the point of detonation..? I won't be able to pull the head until the end of the week, so I'm just speculating until then.

 

01 got graphite gaskets few got mls.2002 were mls along with coated pistons.

 

Bent rod or mushroomed bearing eek that would f-en suck.

 

There's a chance of a bent rod or broken piston if enough water made it through.

 

If that's the case, I'm swapping in an LY6 with some head studs and then this truck is done. No more mods. We'll see...
