Still smoking from dipstick
My cousin just got a 95, 850 turbo with 137k, I checked it out before she bought it to make sure the rear main seal wasnt leaking. I did notice it has a lot of smoke coming out the dipstick and breather. We removed the intake and did the oil seperator and PTC cleaning. The car runs great but it still smokes a lot from the dipstick? I did not do a compression test but I did use a vacume gauge to check the state of the motor and got 21lb rock solid at idle and nice smooth operation.
Any ideas about what could be causing the smoking?

If the system was clogged so bad that you had to clean gunk out of the block, it will usually smoke for about 500 to 1000 miles. Some people run some Seafoam through the system to burn that out.
Did you replace ALL of the hoses, elbows, lines?

I did not replace the hoses and lines but I did throughly clean them.
I cleaned the seperator box by soaking it in gas for an hour. I then flushed it out with water from the garden house and watched it freely flow I cleaned the hoses and there was no blockage.
Another mechanic cleaned the PTC valve down on the intake.

Just wanted to be clear, did you clean out the old PCV/oil separator or did you replace it with a new one ??

No new parts, just cleaned everything. Anyway, our S70 smoked a little for a while after I did it, I believe for about 1,000 miles. I wouldn't worry about it if the vac/pressure is right. My wagon was clogged up pretty bad and did NOT smoke so smoking is a symptom not the real proof.

LOL, That was a good one.
As I said, mine did NOT smoke, was plugged up and DID blow the RMS. So, use the dip stick as a symptom and keep the system serviced every 60,000 like the manual says.
Most people replace all the hoses etc. because they usually break when it's taken apart. The lines also rarely can keep a good seal when dismantaled. But hey, if you can tear it down, put it back together clean, more power to you. Just try to keep the thing off the crack pipe (head gasket).

the flame trap valve its self should be cleaned every oil change anyway. I do it to every car that come in for our "Full Service"
take the valve off the intake elbow (or for turbo cars remove the hose entirely, easier that way) clean it or just replace it and good to go.
Its all about the maintenance you preform on the car, how you drive, and how far you drive distance wise per trip.
If it smokes after you replace the system, you ither did something wrong, or got bigger problems.

I Agree
I'm sure for the price of that oil change, I could buy 2 houses in Detroit.
Once again we are simpatico.
Respectfully have to disagree on this one.
At best these are 15 year old cars. I know everyone freaks out about the PCV system. (And some justifiably so) Can your RMS blow out due to pressure? Hells Yeah! Is the system by design FUBAR? Absoforkinlutely! But here is the thing. If the system breaths. It breaths. How old is the internal combustion engine again? Not trying to be a D-Bag, but a lot of this **** is hype. And unfortunately, some buy in to it so much, that the church of Scientology would cream themselves for their addresses. Is Maintenance key? Obviously. But to feel you have to constantly replace a whole system that isn't damaged is ridiculous. It's a ****ing oil trap and some hoses people. Unless it's clogged or broken, your money is better spent on a snuggie, a chia pet, a clapper, or some lingerie for your mistress. Bigger problems?? Possibly for some. But the long and the short of it, is that no one really has a clue, why an unobstructed PCV system "still smokes the pipe." Cancer will be cured before someone figures it out. If your tube is smoking pull the flame trap. If it smokes there. Then you really have no problem except the possibility of engine wear. RSPI put it best. Use the smoking stick as a symptom to a problem. Or better yet. Use it to scare a seller in to lowering the asking price.

Keep in mind I always replace everything, never clean and reuse.
It is important to idle the engine for awhile after doing the job, before you even try to move it or even drive it.
If you let a flame trap go too long without replacing it, you will destroy your engine, plain and simple.
It is not hype, it is normal that PCV systems on all cars and trucks must be serviced at some point.
Oh and "full service" only cost $160 Thats oil, trans, air filter, cabin filter, replace any bulbs necessary, lube hinges and locks -- pretty much get it back in tip top shape; it does not include spark plug or ignition components. The car is checked out and made sure everything is in good running order. It usually takes about an hour to do a full service and trust me $160 is cheap.

I take the entire intake hose off and clean the valve while it is still on the hose. I learned very quickly that that valve on the turbo cars are a PITA to get off and back on because of the location and material the intake hose is made of.
