The cam timing was never off to begin with. The guides where not installed right at the machine shop so the valves are kinda overlapping the seal by just a hair. I just don't understand how I did not notice it to begin with.

This doesnt make any sense to me. Can you clarify?Quote:

It is really hard to explain without you being able to physically see it, I tried to get pictures but I cannot get enough light in to show it.Quote:

I think I follow you. This would mean the head is junk wouldn't it. I thought that old valve guides were pressed out not drilled. Drilling seems to leave the opportunity to not drill straight, which is what sounds like happened if I follow you.
Yea, the head is no good now. Totally not worth rebuilding as it would need sooo much work. The only problem I have is now I have 2 92 heads and my car is a 93 so I have to convert the harness to the 92 single CAS.
Thats really easy to do though.
oh yea, I know, I had it converted before but changed it back because I was having this issue with the car.Quote:

I swear I'm cursed...I got the rear head replaced and started the car up. It runs...barely. I turn the injectors off on cylinder 1 and 2 and there is no change. I dunno wtf happened.
If anyone knows of a cheap tt long block, please let me know as I am at my wits end.
