Rear engine oil leaks may occur because Subaru used a plastic oil baffle plate that failed. This issue is often misdiagnosed as a crankshaft rear oil seal leak or an oil pan gasket leak. Subaru released an updated design of the baffle plate made from aluminum that stops the oil leak.

Same thing. A mechanic diagnosed it as a rear main seal leak. But I didn't quite think so. I used an additive that would have corrected the leak if it was a main seal. I did not. Now I know the real problem. Thankyou!
