P80 Positive Temp Coefficient Nipple "PTC VALVE" To drill, or not to drill

[xHeart]

... And non-turbo cars like yours do not have a PTC. You may be thinking of the flame trap orifice specific to NA cars, which can be accessed by removing the air intake from the front grill and/or the air filter box for full access.

Flame trap:

Im glad to finely know what PTC stands for, though I've forgotten already. Although I once thought it made sense to enlarge the hole, now I don't, though its reason to be is not clear. I do think that a one way valve should be put on the small vac line from the manifold to allow vac only and no turbo pressure into the PTC area.

I first posted these in ZionXIX's thread viewtopic.php?f=1&t=84698. It's been 18 months now, with no ill effects on my 95 R.

Literally not a single issue since I followed your suggestion. I am considering upgrade the pcv hose to a copper pipe when I change out the pcv.

I did this on my non turbo although I used a very tough flexible fuel line. 5/8" I think. My wacky manifold shape requires some flexy bending. I can say that the pcv properly functions. But I still suspect that I have blow-by as my oil smokes every 3000 miles. I just learned to accept that it means that I need to change my oil. Hahahaha

If anyone needs a replacement nipple .......I have one from a snorkel replacement.

Volvo put it there for a reason. Don't mess with it other than making sure it works by cleaning it.

My two cents.

PS that goes for things like cats and other stuff as well.

I thought cats cleaned themselves? Hence all the hairballs. It’s definitely good to just leave them where they are.

You are going to fit in here really well.

Don't mess with it still applies though.
