Engine Oil Seeping from Rear Main Seal

@parakey your googling image skills are impeccable!

So based on Mitevo's feedback it might just be this black thing which Parakey has identified as the oil separator. Anything this plasticky sure will have a o-ring which will probably fail.

Yes this is the one we saw its probably leaking oil, even the pipe is filthy. Lets hope for the best, anyhow still need to take off the intake manifold to gain access.

I know right ! He is a life saver !

Its too tight, if don’t want to lose engine oil i think its best to remove the intake manifold rather than engine oil cooler to gain access.

Will be very difficult to access. Starter & TB seems to be in the way too. Do let us know how it went

Or if it's just a minor leak, why not leave it as it is for the moment?

Hi, if could i would like my car bone dry with no leaking at all. Furthermore if its an easy fix better take care of it before the oil clogged up the other area where it shouldn't be. Furthermore, we can't be 100% sure its the oil separator part that is causing the leakage, since i am determined to dismantle it to check for it, might as well as 100% sure of the issue and get rid of it.

Dear All,

Finally managed to track down the oil leak locations. Just as parakey and Izso pinpointed, the leak starts from the oil trap/separator. The gasket on this thing has shrink by bit and oil seal on the hose also degarded.

Does anyone know whether the oil separator is a replacement item or i can reuse it with adding gasket gum ?

If it's plastic it'll be probably be a replacement item. Might have deformed over the years

Pls dont use back by adding gasket maker. The part is hard to reach and not worth the try.

Better option is to replace the rubber gasket. A tad more expensive is to replace the plastic part.

What's actually inside the box ? Some says its actually empty inside, just for blow by gases to goes through and goes back into engine.

Understanding Volvo's spare parts nature, they won't make any gasket for this thing, it will be the whole thing. If the price isn't ridiculously priced then i will replace the whole thing.

Hidden gold. Great place to hide your stash of drugs... hehehehe.

I think it's just a place for the oil to "cool down" and condense then get sucked back in to the engine. Some sort of environmental thing. I honestly have no idea. Don't own a Volvo, never have either.

As far as we look inside this piece of non-environmental box, its nothing inside but some sort of wire mash. When we pour some oil in, it just went right through to the other side. It simply to trap any blow by gases that might carry oil along with it. The diagnose return that the box is fully functional with only lower part of the gasket expired. My repair is too use gasket gum to glue it dead and reroute the oil passage to a catch can. Don't need this damn thing at all and don't need to spend 650 bucks for this thing

650 is steep for the repair.
From the way u describe it, its like an oil catch can except the oil is not collected in a can but recycled back to the engine.

Yes its a stock crappy catch can that installed on to the engine block. Inside has nothing else rather than wire mesh. I will report back when the repair is done.

Had a few friends who own Volvo before, most sold them off saying high maintenance. Only those with the old 244 keep them until cannot repair.....lol

Dang, Volvo parts are so expensive. These oil traps are supposed to last only 100k km. It makes e46 parts dirt cheap.

If it's only the rubber seal that's causing the minor leak, I guess you can try o ring cords.
