2002 volvo s60 2.4t PCV still blocked after service/replacement

Post by cfelberg » Fri Nov 08, 2019 7:49 pm

Well, I could really use some helpful insight. I had a pretty bad front cam leak so before I replaced those seals I tackled the likely culprit, the pcv system (car has 160,000 and it looks like it was never replaced). I got the pcv kit and replaced all the hoses and fittings and oil box. I also cleaned out the blocked passages from the oil box to the block and blew air through passage and pretty sure I felt air coming through oil fill hole. Also, I had the dip stick tube removed at the time and oil jumped out of that hole so I assumed the passage was clear to the pan. So after I completed all the pcv repairs and replaced all the cam seals I have no oil leaking and all seems to be good, but then when I did the glove test on the oil fill tube it passed when the car was idling (glove was sucking in) but did not pass (glove expanded) when car was under load (revved up to 2500 rpm while in drive with brake on). I wanted to ask where the most likely blockage point would be on the "turbo" circuit of this pcv system. I also looked at the PTC valve and that was completely clear. I'm worried this may cause me to blow a cam seal again - Any advice would be greatly appreciated! Thanks! Chad

Didn't know that. Is that true?

Unfortunately, yes, this is the situation on my car - I got this information watching a youtube video titled "Volvo PCV system checking and special tools"

I don't know if any of these cars, especially a turbo with high mileage, would show negative crankcase pressure under that test scenario.

thanks for the reply, but should it show definite positive pressure to the extent to inflate the glove - should I worry about this pressure pushing my cam seals out again when driving?

I've never heard of a "PCV Glove Test" under load, only familiar with the glove test on the oil fill at idle. Are you seeing any new oil leaks on the engine?

If you are confident that you replaced the system correctly, I'd carry on as if it's repaired and only monitor for new leaks.

Thanks for the reply - One reason why I am a little concerned is that I had done the glove test just at idle before and it was always ok, and then the cam seal let loose. Upon doing research for this job I came upon other posts (google pcv sytem mythes and testing) and the youtube video mentioned previously that discussed the two pcv circuits (idle and cruise or boost) and that both should be tested. I feel I completed the job correctly but am not sure what to look at next if in fact this is a problem.

You don’t want high crankcase pressure under any running conditions. High crankcase pressure will pop cam seals and Rear eng one seal,too. Ugh.

Another indicator of high crankcase pressure is the oil dip stick may be pushed up (due to the pressure). Have you checked for this after running it at higher rpm's? If the dip stick is still seated, I'd think you are good, or the pressure isn't so high as to cause a problem.

I'll keep on eye on the dipstick. I checked it a couple of times within the last few days and it may have moved up a millimeter if at all. I'm just not sure what the next step would be - I was hoping there was an item that I overlooked that was causing a blockage. Thanks!
