Hello guys I’m David from LA Lincoln Alabama. I have a 1996 RAV4 with an oil leak. My mechanic is saying I have a main seal leak, but I’m just not 100% sure that what it is. She has 155000 miles. I know there's a small valve cover leak. He says to not fix that it would just put more pressure on the main seal. I am adding I’d say 1 1/5 qts. Per 3000 miles. Is she worth fixing?
