highest egt's it has seen since I rebuilt the motor is 1100deg.

I was just going to ask if I could remove the converter bolts and start the motor.

 

Did it all the time when I worked at the dealership

Do you have the stock Flexplate or a billet?

 

good glad to hear I can do that, that will at least eliminate or narrow it down. I have a stock flex plate, I have plans on a complete transmission rebuild in the future, I will have goerend brothers do it, their shop is only 12 miles from me, and I have been using them for years. But first I have to save up some money I did not plan on rebuilding the engine 5 months ago.

 

Finely got around to check on my truck today. I took all the torque converter bolts and started it. I don't think I hear the noise anymore. Also as I move the torque converter back and forth I hear a clunking sound, I don't think that is normal??? Back to my first post where I said I found bits of metal in the oil filter when I cut it apart, might be from me cutting it open, I would of thought if there had been metal in the filter I would of shown on the oil test.

 

Check the flex plate for cracks.

 

I looked it over as best I could. Put all the bolts back in, now the noise is gone. I am baffled.

 

were all the bolts tight when you took them out of the torque converter?

 

yes all bolts tight. what is the best or easy way to check the flex plate for cracks, with out taking it out.
