Vehicle oil leak.?

I own a Legacy and just fixed an oil leak that was coming from the front of the engine. It was the oil pump o-ring. The oil pump is driven by the cam timing belt and is installed over the crankshaft. The little o-ring flattens over time, and the direct pressure from the pump is too much for a one inch o-ring. BTW, the main seal is installed in the oil pump housing.

For further details, go to this web site and do a search on oil pump to check out old threads. There are very helpful people in there with a lot of knowledge about Subies.

Nothing will slow a main leak. It has to be replaced. Anything that sealed that kind of leak would also seal a whole lot of oil passages that you really don't want sealed and trash the engine.

Your not going to fix a leak from the main seal with that kind of stuff, you need to go take it to get fixed.

you can't fix a main seal leak with that junk, maybe just enough to trade it off.

there is a product made by solderseal it called bearing and seal you can try that but the best bet is to get it fixed

looks like the thermostat caught and it stop circulating ! then after awhile it spread out and started to bypass back ! greater effective get the thermostat replaced or it would circulate away you sitting !
