Wrapped up the PCV job on the R. I replaced the metal pipe to the PTC valve with some 5/8" oil compatible hose in order to help further relieve crankcase pressure. I'll be drilling out the PTC sometime soon to finish this upgrade.

Shouldn't be blowing out any seals now!

The PTC Nipple

The PTC (Positive Temperature Coefficient) Nipple is just a hole, or Orfice nipple , to use the Volvo term. Its often mistakenly called a valve as it has an electrical connection, but that is just a heating element to keep the sludge from condensing and blocking it. It is a valve in the sense that it regulates vacuum to the Positive Crankcase Ventilation system, but it does not open and close like most think of a valve.

It is often drilled out, when in fact it is a required cleaning maintenance item every 60k miles on a new car, and (my recommendation) 30k on an old Volvo.

The reaction to "Hey the PTC is clogged, lets drill it out" should be "Why didn't I clean this per schedule?"

No judging here.

So in your opinion here , should I drill this out when I install my new PCV system ? My car has 147K on it. I just bought the car last june and it's just now starting to build pressure in the crank case. The glove test fills the glove slowly.

Worthy of Forum thread since opinions vary here.

That's correct, not actually a valve. It's open all the time.

The only reason I'd drill it out is to alleviate any more restriction. I upgraded to a 5/8" hose coming from the oil separator, so I figured I'd finish the job by enlarging the PTC.

Yesterday I went to an AC specialist in my hometown Zwolle (Netherlands). Usally I fix everything myself, well, at least I try to do, but I'm not experienced with AC's nor do I have the tools/equipment to do it properly. The AC on my 1998 S70 didn't cool anymore, not at all. After an inspection my guy told me the condensor had a leak and the compressor needed some maintenance. I don't know how to say it in English, but the compressor has a clutch and the gap between the clutch and the compressor can get too big sometimes, you guys probably know what I mean. So, after paying a 500 dollar bill my S70 has icecold AC again :-) I also noticed that the S70 can run pretty economic. I went from Zwolle (Netherlands) to Bruges (Belgium) last weekend and I managed to get 12,8 kilometers per liter fuel (30,16 miles per gallon in US terms, 36,22 mpg in UK terms) so that really made me smile. Have a good Easter!

Happy Easter to you and everyone else here as well!

That's a pretty common problem with these cars. My cousin had a problem with that on his S70, the clutch was wobbling around and had a large gap. 30 MPG would be really nice, I get about 20 with my driving style around here. My R averages about 17-18, but I've been disconnecting the battery and doing lots of testing lately. I'm sure that will go up once I start driving it normally.

So I got the engine in the 850 freed up today! I was testing a few things that people were interested in if I parted it out, and I just turned the key for the heck of it. After the starter bumped a couple times and did nothing, I turned the key again and the engine started cranking and spraying Marvel like a geyser! Conveniently enough, we started tearing it down a little bit yesterday, but fortunately there wasn't a lot we removed. As soon as I was able to crank the car, I went an reassembled everything. It hasn't started yet, but I've confirmed it's getting fuel. I'll continue diagnostics tomorrow when it's not raining.
If I can get it running well, I'm going to fix it up. I didn't want to part it out in the first place just because it's lower mileage and is a clean rust-free chassis. According to the diagnostic connector, it only has 158k miles.
