A high oil level in a stock depth low capacity pan is not a good idea but with a windage tray it should not have caused this.

The pickup being slightly higher than ideal is not a big deal to me either.....unless oil is trapped up top and you generally will see oil pressure fluctuations if the level was to low and pump was starving.....

Think about just how the oil in the pan is moving around in a wheelstanding car....sitting on a dyno its not under any of those forces....

Small blocks "like" to kill #5 & #6 rods more than any others.....Don't ask me why …..

I hope you find a cause and hate seeing stuff like this....but it happens unfortunately.....

I put the plug back in under the rear cap, it's there for sure.
