Back to square one AGAIN:








Thankfully the cylinder walls look good, the pistons had ZERO signs of detonation and the last datalog i had show 0.02 knock at the most and it was so few times even in full boost. I pulled the cam straps and found very miniscule amounts of copper in a few of them. Super light scoring so thats not an issue really. It can be micropolished out thankfully. The valve seals im sure arent in the best of shape so the whole head is going to get rebuilt.

I need to pull the bottom end out, take it apart and see what exactly is shot. Hopefully the rods are good and so are the pistons. If I can get away with only replacing the crankshaft and the bearings then Ill be ok. It all remains to be seen.Im bummed out but i know this crap needs to be put back together and I just want to get it done and move on.

well at least the whole thing isn't FUBAR'd. good luck dude, don't give up. I know you feel like **** and want to (cause I did too when my **** blew) just get rid of it, but it will all be worth it when its up and running solid again.

This blows man. I feel like we're living in a similar hell. I'm so sick of pulling and rebuilding my engine(s). I just want to drive my ******* car.
