Well..... now i am really lost!
Pulled the trans and EVERYTHING looked great, all bolts were tight, all welds fine, all weights fine...seriously everything fine.....except some of the teeth on the flex plate were munched.
Since the only thing that changed from working great to having all these problems was having the torque converter re-stalled, we figured we needed to try and isolate where the problem is coming from.
Decided to bolt the flex plate back on, pull the bell housing off the trans and bolt to motor, bolt starter back to bell housing. Now we started the engine with no trans on, SAME problem, nasty harsh grind!! Sticking our head up in the bell housing hole and watching the starter engage while turning over...once again everything is fine. Starter gear comes out and retracts fine, makes the nasty harsh sound and shoots little metal shavings all over (coming off the flex plate)
So I ask... how could the bell housing only bolt on one way and the flex plate only bolt on one way and the starter only bolt on one way... cause this problem I mean, obviously something is out of whack. My harmonic balancer has a wobble, so does anyone think that I could have a problem with my crank maybe has some sway or walk causing the flex plate to be out of line with the starter?? Or has anyone ever tested or know where to test a flex plate for trueness, something has to be miss aligned, I just have a hard time thinking the flex plate is bent or out of true since its SFI approved which should be stronger.
We are just at a complete loss… the only thing I can think of is need to test the flex plate for trueness if it checks out fine then it has to be in the motors rotating assembly. It’s just we pulled the trans and torque converter and are still experiencing the problem…… what could this be?? Need to find the problem so we have time to fix it and not miss any races this year.
