Subaru H6 Upper Oil Pan Replacement Question

Featured Replies

I have a 2003 Subaru H6 3.0l and the upper oil pan is leaking.  Does the engine need to come out of the car to replace it?

Thanks..

I don't know for sure that the engine has to come out, but I can guarantee pulling the engine would make it easier to get to.

 

That said, this is a part that is sealed at the factory with RTV, and will probably never leak.

More often than not leaks in that area are caused by Head gaskets, valve cover gaskets, or a leaking oil seal or o-ring.

If you can't see exactly where the leak is coming from, clean the area well with purple power or engine degreaser, and try to find the exact source of the leak. 99.99% chance its NOT the oil pan.

I second making sure you know exactly where the leak is.

 

My lower pan leaked- it rusted through!

It could be the o-ring for the Oil cooler (between filter and block)

 

They leak all the time and look like could be upper pan but isn't

 

Never seen a 3.0 need the pan resealed.......replaced from rust.....but not leaking seal.

Especially not the upper aluminum pan to block seal...
