1999 V70 T5 PCV Intake Manifold Re Installation DIY

The late P80 cars have thermostatted PCV. Yeah! I’m convinced they clog much less than early P80s. I changed my oil with Dino every 5k with this car and really had minimal sludging.

Reinstalling the manifold is hard though as you have extra stuff.

What Makes a PTC Valve Work?

I always wondered what was inside the PTC valve and how it worked electrically, so I decided to take apart one of the ones I harvested from the junkyard a few months ago.

I removed the rubber bushing by prying it up and off. Then I used a hacksaw to slice down one side of the main PTC tube. While I was sawing the last bit of the side, when the blade dug into the bottom piece it popped off. The bottom piece is also copper and was soldered onto the copper tube.
