Hey all, I swear camaros.net is the best troubleshooting source on the net. Here's the deal, I just rebuilt a TPI 305 for my 85 IROC. Now, the beaut runs like a damn top, and have about 400 miles on it so far. I have been breaking it in nicely, driving sane, changed the oil at 300 miles (looked great), and keeping the RPMs below 3000. However, at 3000 RPM (Typically where I shift at the latest) it will puff smoke between gears. I have stopped on a straightaway, and from idle to 3000 in 1st gear, at about 2/3 throttle, it just took off, NO SMOKE. I stopped the car, put it in park, and held the gas, no smoke up until about 3000 and up. Did I "fudge" up the ring install? Is there any hope? Do I need to perform rebuild #2? Everything is new if not rebuilt, it had valve guide problems before, but these are different symptoms, and they were replaced anyway. I'm hoping the rings just need to seat more completely and that I just need to take it easy. Thanks for the help, I hope for good news!
