too much boost=rod bearings?

[SevensOdd]

Hey i was wondering if too much boost on a pretty much stock system would cause my rod bearings to die?

Too much boost might not be the only cause but it certainly isn't out of the question.

If you're knocking badly due to overboosting with a bad tune, that'd beat up the bearings. But as alice points out, there are other causes.

well i put my tranny back in today, after the car sat since last november. Took it for a drive, fixing vaccum leaks as i went, and started hearing some bad knocks after a while, while i was off the throttle. Lucky for me i was almost home. So i limped back to my garage, took the vavle cover off, and the heads are fine. So im pretty sure it is the rod bearings. The only problem is how? I was without a boost guage and just kind of eyeballed my MBC. My guess was too much boost.

me either....

def. need to uh, not do that?

but seriously yea, make sure you have the right still installed so you can tell what's going on. I couldn't imagine knowing the only reason i messed up my motor was because i didn't have something as simple as a boost gauge..

Yea, a cheap $25 used boost gauge would have helped. Did you add more fuel or just boost. I have fixed two 1G's where the owner just put on a MBC and turned it up.
