oil catch can

Post by jlh3rd »

hello
I have a 2012, s60, t5 with about 56000 miles. I just replaced the pcv system due to the common issue with this part. I've been reading up on oil catch cans and wondering if that is something I should do to this car. If so, has anyone done this? if so, any instructions on how you did it and what manufacturer you purchased the kit from?
thanks.

Hello,

I am not a expert but do have the PCV system off my 2012 S60 T5 as we speak. The "catch cans" you mention I believe are after market devices designed to trap and return oil to the crankcase, not the intake?

The can would need to install in the rubber line from the factory PCV to top of the cylinder head. It would require some fairly long hoses that might cause the oil/air moving in them to cool significantly which can cause problems. Also you must somehow drain the can either manually or a return line.

The factory unit is very expensive, but I think will do a good job when new. But I do think it needs to be changed every 40,000 miles perhaps? When it starts to fail it can cause big problems.

The issue will not be fixed by the catch can as the issue is (in my opinion) likely excessive crank case pressure, not excessive oil in the intake stream. The catch can will remove more oil from the return line, but it will not move more air/oil stream from the crankcase.

Best of luck with it.
