Cute little trick to diagnose blocked CCV system...

424030 91
I just came across this interesting little trick for diagnosing blocked CCV in the Volvo forum:

With the oil cap sealed, engine on, stick a balloon over the dipstick tube and see if it inflates. If it inflates you need to service the PCV system.


I think he meant with the dipstick removed, so the balloon goes over the dipstick housing.

No balloon, no problem, get an old dish washing glove, cut a "finger" off and tie it with rubber band.

That was me! Thanks to RDL for a fast, cordial, helpful response! Seems obvious now, but I was not sure! Great forum!

As I told him...

"Great. That's perfect! Seems like a "duh" moment now. I was just looking at that piece a couple days ago as I was picking individual pieces of dog food out from under my fuel rail with a retriever "pick up" tool... Dern mice!

Thanks a bunch for the speed and courtesy! I have to admit reading some things on a CCV delete and an oil catch can are making me ambivalent about which direction to head! I need to do more research on those alternatives.

Best wishes!"

...unless you guys want to tell me why the delete is a bad idea!? Heh...
