ENGINE/CAR: 33 gtst, rb25det
FAILURE: still running, clunking powerless pos tho. pull apart shows very badly scored main bearings. 5 out of 6 lol
FACTORS INFLUENCING FAILURE: found what was left of an exhaust manifold bolt that had been drilled out of the head up in there. I assume it was some smaller shavings etc. that caused the damage to the bearings tho. Not sure how it got from the head to the sump??
STATE OF TUNE: just finished turbo swap, previously stock turbo well tuned. just started making noise after 5 min turned back on.
COMMENTS: dont lose bolts i guess. can be fixed with just new set of bearings and a good clean, hopefully i will do something else while its out. not a great experience financially but i am learning a lot
