UPDATE..

so a month or so ago i was taking the girls to school in the pontiac, she started to sound a little rough...the more i drove it the rougher and rougher she ran. by the time i got to their school it was literally poping and sputtering as we pulled up. she would barely idle, it sounded like there was someone inside the motor trying to bang their way out with a ball peen hammer....BANG..BANG..BANG..BANG..BANG. so i called triple AAA. i had it towed home and just threw it in the garage and put it on the back burner thinking it had let a rod go or something. sat for about a month then i had some time to tinker with it. i pulled the valve covers off to find that my number 6 exhaust rocker had backed almost completely off..as in like 1/2 inch of lash.

then i noticed that the number 6 intake pushrod was bent. im theorizing that the ex valve backed up not allowing exhaust to exit the motor causing alot of cylinder pressure that the intake valve now had to push into to causing the push rod to bend and when it did open it would POP into the intake.

so i installed new pushrods and fired her up and she purred like a kitten (well a kitten with piston slap) anyways, i was completely amazed how much noise and what kind of noise exhaust gasses can make when they are forced to exit out the intake.

she is back on the road now, my fiancee and I spent most of the weekend with the top down running around. BUUUTT i think ive damaged my torque converter now. its making a funny noise at WOT. the tranny shop that built it for me sent me a new on i just havent had the time to install it yet.

PS and the rings seem to finally be seating
