3rd cylendar issue?

[96GST16g]

the first time i blew my motor it would only hold 30% of air capasity in the 3rd cylendar and the secound time i spun a bearing on the 3rd cylendar could this be linked to a certain issue or may be a shitty build? running a 16g 3 inch turbo back exhaust and no tuner stock boost and it blew after 100 miles of rebuild secound time first time had 169k on original motor as far as i know

Shitty rebuild and the fact you don't have a tune is definitely not helping.

yea im not beating on it what so ever i asked the shop that built it and they said i didnt sell you the bearings so not my fault

If you build motors as good as you type, maybe its time for a virgin stocker :) Kia even.

A spun bearing has nothing to do with poor leakdown test results. If you certainly never beat on the car (never hit boost, no revs beyond what is required to shift) then it was a problem with the build.

i didnt build the motor.... and i never went above 3 grand for rpms may be a little bit of boost

[96GST16g]

and the leak down test was the first time..the secound was pretty obvious with a rod knock

[Shane@DBPerformance]

If you didn't boost it, then it probably isn't a tune issue. Could be an oil pump problem, oil pickup problem, build problem, bearing problem, or some other random or freak thing.

Sure it can, a spun bearing would prevent oil getting up top, causing cylinder wall scoring. Theres obviously an oil starvation problem somewhere.
