Finally got everything checked out. Turns out it was getting some water past the intake seat from a previous repair. The other thing we found is the cam bearings are burnt up as well. Not sure why and have never had that issue before. Only other issue we found is the fitment of the one piece BOP rear main seal in the MR-1 block. Looks like the seal is a bit wide for the groove in the cap and block. Has anyone come across this before?
