Theres 191,000 miles on the engine. 1st problem i put 5 quarts in the engine and removed the lid that covers the pistons and theirs no oil their around them. I check the dip stick its well over the max. My 2nd problem is when i hit the gas it sound and feel like things are grinding and i hear spark sounds from the driver side. Also one out of the 16 piston screws is strip, will thats cause any type of problems?

 

Oil pump failed. Engine damage.

 

So i be clear, you saying the engine done for or its just a oil pump?
