I'm pulling my 2004.5 s40 T5 fwd automatic Volvo's engine to replace a rear main seal since I'm apparently a masochist. I'm going to replace the oil pan gasket and the oil filter housing and pcv system's gasket where it attaches to the block since theres a bit of a leak there. I've been looking around and can't seem to figure out what gasket I need though. Are the oil pan and filter gaskets both made of liquid gasket material or am I missing something?

Theres so much oil under the rear and behind the engine that I'm not 100% sure whats leaking but the worst case scenario is the RMS so thats what I'm expecting. I figure I'll replace all those seals while I'm at it since I only want to do this once.

I checked the pcv system using the old "rubber glove over the oil fill hole" trick and it showed a vacuum so I think the system is ok.

I checked the turbo oil return line, and it looks like its been replaced already, but the PO used a gasket sealer instead of an o-ring so I'll take care of that too.

Before I do this stuff I'll clean the engine up with non-chlorinated brake cleaner and run it for a few minutes to try to pinpoint the leak. Hopefully its not the RMS but we'll see. Any input is helpful. Thanks in advance.

I'll post pictures tonight if it'll be helpful.

 

The oil pan uses an anaerobic sealer, which is a liquid gasket that is rolled on and dries in the absence of air once assembled.
