Mechanical gauge oil pressure after cranking 50psi, 70-80 when I rev it a bit... allthru with knock coming out I am affraid to...The oil pressure is good?
The crank end play is now good
Short out spark one cylinder at a time and try to isolate knock
Pull the heads off
By the looks of those bearings it may have a loose piston
Real hard to inspect pistons and wrist pins with them still in the block
That means pulling and tearing the engine down..Wrist pin.
Thnx. Yap, got that part "flex"-plate but as I chase knock source after crank play fix I automatically saw this as a potential pushing of the crank too much forward or converter balooning or whatever...That is why they call it a flex plate
Early E4OD in trucks was so bad it punched holes in a few converters and made them leak fluid
