Composite 2jz headgasket
Hey guys, so after doing my headgasket (was blowing a lot of smoke), the problem is even worse now (no smoke but mixing of oil into coolant...no coolant in the oil thankfully). Anyways, I used an OEM TT headgasket (MLS) and ARP studs. I had the head decked but not the block. I am hesitant to use another metal HG as I fear the block may not be smooth enough. Does anyone know of a composite HG for the 2JZ? I know I shouldnt spray copper on the metal HG but I really want to fix this the next time around.
Thank you
Wyatt

how clean was the surface of the block . .did you use 1000 grit wet sand paper and alittle motor oil to smooth the surface .. how did you do the torquing of the headstuds .. did you use a cheapo click type torque wrench or the expensive digital self calibrating type ( which is what i use) ,did you follow the correct sequence and do it in 3 steps to final torque . did you test for stud/nut actually holding torque which is a final step alot dont do which usually tells you if the alum in the head has gotten to soft and the nut is galling into head giving false readings
