98 V70: Hard Plastic PCV Pipe Broken

Post by **cn90** » 11 Nov 2016, 20:34

Here you go, I wrote that DIY 4 years ago. So far so good, the 5/8-inch heater hose is doing very well.
Just pay attention to where the curves are and don't create a kink and you will be fine.

Get the metal unit from a '99+ car instead of my Cooper pipe.

Glad the masters have responded as they've actually done this upgrade. Mine is "patched" for now until cooler weather prevails. Note you might want to add a nylon 90° elbow to prevent the rubber hose from kinking where it makes a left hand turn to head back towards the intake pipe. When using copper or aluminum, this won't be required.

User trying has now documented several better options for the PCV, see https://www.matthewsvolvosite.com/forums/vie ... hp?t=76504. Including how to deal with the kink, what kind of hose to get.
