I have a major oil leak in my 2011 Marine Power 5.7 vortec engine. I was crusing along at 3500 RPM and noticed my oil pressure drop very quickly. Turned off motor and then noticed a lot of oil in the bilge. Im talking quarts. Got it home and cleaned up all the oil.
Re-filled the oil and did not see any leaks after filling but not running the engine
My question is this, is there anything else I could be missing? If it’s the rear main seal, I know I have to pull the motor but not sure how big a job replacing the seal is. Any input would be appreciaited before I go through the trouble to pull the motor.

- Started the engine but it only got to 20 psi in pressure where nornmally its between 40-60.
- Once again lots of oil in bilge
- Oil pressure sender and attached hobbs switch had no oil leak
- Remote oil filters had no leaks nor did the hoses.
- Oil cooler has no leaks
- Could not see any oil around the intake manifold
