cnc Posted November 30, 2009 Share Posted November 30, 2009 I'm a noob, here. My 93 Loyale wagon has an oil leak that is stinky and loses engine oil. It drips on the catalytic converter. The drip appears to be coming from the passenger side, at the base of the cylinder where a gasket is. I've checked the valve covers and they're tight. Is there a typical problem with an oil leak like this one? Should I try one of those chemicals that stop leaks? I'd say it loses a quart every fillup. Thanks.

GeneralDisorder Posted November 30, 2009 Share Posted November 30, 2009 1 quart per 3k miles is not excessive according to Subaru. Sounds like you probably have leaky valve cover's. Just pull them off, clean up the cover and the rubber gasket - degrease them with some brake cleaner and then re-install with RTV on both sides of the rubber. Don't forget to RTV the rubber bolt washers too. Reaplacing them with new one's only lasts a short time and they begin weeping again. RTV will be permanent till you take the cover's off.
