Crank end play, destroyed converter, 408 nightmare
Hi guys,
long story, built the 408 about 2 years ago, was my first engine and i did a lot of mistakes, always had some problems with it, ran really hot all the time, had really high oil pressure (up to 100psi), and then suddenly my new converter (hughes 2500stall) was completely destroyed, the 2 impeller had contact.
I thought it was just a bad product and got a new one from summit, but there was so much metal in the trans oil, so i took the 904 out (just the trans), paid a guy 900€ to clean it up, he said he replaced a few bearings but generally nothing wrong with the trans just cleaned it.
Put it back in with the new converter and it worked but when i shifted 2nd to 3rd gear it was slipping so i took out engine + trans 2 weeks ago cause i needed to overlook the engine anyway.
Gave the trans to the guy again, he said he will check it again.
Just before i removed heads and oil pan (cause i want to install a thicker head gasket to get my compression from 11.6 down to 10.5, and got a new milodon oil pan, used the stock 360 pan with a windage tray till now) and i noticed a massive crank end play, the thrust bearing looks worn out (probably hard to see in the pics) on the back side of the engine have not pulled the crank till now.
What can be the reason for all this? Did the end play destroyed the converter or did the damaged converter caused the end play?
Also the fel pro head gaskets have been deformed when took off the heads.
And there was a lot of metal in the pan there are 3 magnets in there.
Thanks for your help!
