Boring,
Oregon
I recently noticed that my stock talon was heating up quickly, one leakdown test later my headgasket was found at fault. I bought some felpro headbolts and used a new composite headgasket (looked generic imo) that was given to me. Anyways I had done a cold compression test right before I pulled the head and got 155,140,140,160. Well after the headgasket and timing belt but before installing intake manifold, exhaust manifold, ect...I decided to do another cold test for kicks....good thing I did my cold numbers were insane...125,105,105,110 dry and 155,140,140,155 wet....so now my wet numbers are pretty much where my dry numbers where before...odd...so to my question, what am I missing here and what could cause that? I'm open to input, I'm kind of hoping I'm just having a brain fart, I pulled the head again and I'm ordering some arp studs along with a felpro permatorque hg, a combo Ive had no issues with on bastard 20g talon. As for the torque specs maybe I got the wrong one ??I went 57lb/ft, loosen, 15lb/ft, 90degrees, 90degrees on the bolts but when removed the newer headgasket looked as if it had been clamped 1/3 as much as the one I took off on the edges.. Ideas? Hopefully I'm just newbing out ...
