i know it is a hint it is just absolutely outta the question for a while.. u talking about boost?? -

ya boost psi.............anything over 45 is hell on head gaskets dude -

i turned it down to right about 42 psi... heard anything on these cometic gaskets?? -

No but be patient I bet someone here has -

found this from Jason at DieselNut

Cometic has a pretty cool Gasket out, and it can be had with a Oring build in it. No need to machine anything. You do have to make sure the head and the block are flat, no waves or anything. These are MLS gaskets similar to the units on the CR trucks. I would sugest trying one of those along with some 12mm studs and I think that will work fine, as long as you don't have some crazy twins set up or something, but you will have to find more fuel before getting that kind of boost.

Is your gasket blown currently?

alright.. every single one of the gaskets i've blown have been on a friday.. 6 of them.. all on fridays.. hey it gives me time to get some good info from here though.. -

simple fix there........quit drivin on fridays


damn it dude..........6 gaskets now, do you know the definition of insanity, its continuing to do the same thing over and over again expecting different results -

not worried about driving it now.. i forget till it happens.. actually i just now realized that they all happened on friday..

the thing that pisses me off is once its had a heat cycle or 2 though it the thing will hold 60 psi.. but if u even touch the pedal without a warmup of at least 5 mins.. even if u dont build any boost.. it will still blow.. -

One or both surfaces is not flat then. Get a good straightedge on it next time its off, and I bet you will be shocked it held any cylinder pressure, let alone boosted cylinder pressure.
How much drive pressure is your turbo making? Thats just as bad if not worse than boost. -

Black smoke is just advertised horsepower!!!

I had both surfaces machined ts machined on the 2nd gasket.. they have been just fine since then...i dont know how much drive pressure its making.. -

I haven't talked to Cometic lately, but last I heard they were having issues with them not sealing. So, back to square one.

Where are you blowing the gasket out at? Is there a pattern to the failures?

You had the block decked? Again, I want to know if you have a pattern to the failure points.

My first impression is something is either not flat or not clamping down correctly, because you should not have problems without boost, unless for some reason timing is so far advanced that you get serious cylinder pressures. Drive pressure shouldn't be much of an issue until the turbo is singing. -

All but one have been right on the front of the motor.. timing should be fine with just an edge comp.. what is decking the block?? -

IN order to get the block surface flat, you have to deck it, which is done with the motor out of the truck in the machine shop. That was what I was asking. So, you probably didn't deck the block, you had the head resurfaced.

I think you need to take a good quality straight edge and a flashlight to your block. You can get a honing stone or lapping stone to clean the surface of the block. -
