do i use the 1.5 head gasket or the 1.6 head gasket? or are they interchangeable?

 

ttt

 

They are interchangeable, it seems like a lot of people go with the d16y8 headgasket. It's really not that hard to find that info out on google or even this forum.

 

go with the 1.6 they are like 29% at carquest auto parts

 

had to go with the 1.5 because it was cheaper. $18 opposed to 35 and seeing *** theyre interchangeable i dont see any prob. goin at it hopefully all goes well. thanks guys

 

well the 18 buck one is a graphite, u should b buyin the 35 which is a three layer metal gasket. The graphite ones are like cardboard and they suck, take it back and get the metal one.

 

^agreed 18 buck and blows in a month or 35 bucks and last years your choice

 

agreed x2 the layered metal are 100% better

 

umm. well its a little too late for that, its already on the car... but now i kno for next time, or if the head gasket blows in a month

 

just remember to keep an eye on it, and that it might cause problems at some point.

 

ok thanks. i might end up replacing the head gasket with the good one anyway.. i didnt have a torque wrench handy at the time so i just tightened the head studs as tight as i could and its leaking oil tremendously. i now have a torque wrench so tomorrow im going to tighten it to specs and if it still leaks ill replace it, if not ill keep a very close eye on it.

 

nvm that.. i dont think the head gasket was leaking. someone pointed out to me it was leaking out of the valve cover which is when i realized i forgot to put the valve cover gasket on lol

 

another question. the head i have is fullyy built and the block is stock. for whatever reason after it warms up its idling around 400rpm and it usually stalls out. i have a stage 2 crower cam and most everything else is supertech internals.

anyone know what could cause the low idle?

 

wow, I would not be able to drive my car with piece of mind knowing that I didint torque down the head, you could have unecessarily warped the head. you are supposed to torque the head to certain specs, and in a certain sequence so there is equal pressure applied to the gasket, so it wont leak. when you put in a new one, go for the 3 layer metal Y8 gasket, I think its a little thinner that the d15 ones, so it will raise compression a tiny bit

 

u dont have a tune, thats y ur idle sucks. Ul probably need more fuel at idle with a bigger cam like urs. I bolted heads on plenty of times with no torque wrench with no problems. The order u bolt it down though is extremely important, i do hope u did that correctly, if u didnt ud know by now

 

im pretty sure its a vacuum leak in my fuel pressure regulator. the engine runs fine no oil leaks anymore.

 

Wow with a fully built head like that id definitely give it a little more respect
