DIY: 1998 Volvo S70 GLT PCV Modification, how to get rid of smoking dipstick!

PCV tutorial - the Ultimate fix

MVS Forum member and beloved contributor CN90 hit another DIY out of the park with his better-than-OEM modification to the P80 Volvo’s PCV crankcase venting system. He writes:

“Many people overhauled the PCV only to find out they still have smoking dipstick (no increased in PCV pressure but simply smoking dipstick, whose significance is unknown).

Some people install a snorkel tube out of a modified oil cap —> intake (ugly looking but works).

Some use plumbing copper pipe to replace the plastic pipe, seemed to work.

My PCV was performed by the Volvo dealer 2 years ago (by previous owner), and from looking at the previous service records, they did a half job. I overhauled the PCV again and found the 2-year-old plastic pipe (from oil trap —> intake) broken, piece of junk.”

CN takes Justin’s world famous PCV repair tutorial, and goes “all in”.
