I have a 99’ 30th anniversary trans am #861. Has 40,xxx miles and I’m the second owner. I’ve put only 800 miles on the car but I’ve owned the car since 2002. It also has not ran since 2002. Long story short. Had bent push rods after I drove it for roughly 600-800 miles twice. Dealership wanted to replace the motor. Extended warranty company did not want to pay. So the car sat in my garage with the top end off of it since 2002. Finally getting it fixed (another long story I won’t get into today).
What I have is multiple piston heads (3) have a gouge from making contact with the heads. (I have pictures if you would like to see) What I’m needing, I’m guessing?? Is the Engine out of the car. Torn down to block. Inspect the block, rebuild the motor. Then get the car back running. Check all lines and flush Gas tank, etc. Finding that person is where I’m at now. Finding a LS1/F body mechanic shop locally might be a problem in Oklahoma.
Just wanted to say hello

My 99 LS1 had problems from the moment I bought it *used... help a noob out. Help explain this to me. I bought the car (1999 30th anniversary Trans Am) with 40,xxx miles. After 600ish miles I got a knock it was a bent push rod. They replaced it. 100-200 miles later it happened again. They pulled the oil pan and found metal shavings in the oil pan. When the top end was removed you can see roughly 2-4 piston heads with marks from hitting the heads.
im sure this could be multiple things but what are a couple of things that could cause this? I have no idea and would love to finally get some info on this. Thanks

Is this car a manual? A mechanical overrev can certainly lead to bent push rods. The stock valve springs are not very strong and don't do well much above the factory rev limiter, so valve float can be expected with a mechanical overrev. Sometimes this can even happen just from hitting the stock limiter too hard (even without accidentally downshifting), but more so if you've raised the limiter beyond the factory 6200rpm.

I was 18 and knew nothing of engines, knock noises. Learned pretty quick on buying a uses sports car for sure. Expensive lesson learned.

lol. Well I drove my trans am for about 1 month before it was tore down and I haven’t drove it since. So it may have been my dads plan to not get it fixed so I wouldn’t kill myself. Lol.
