I only mention it because we're heading into that time of year.
It's cool in the mornings now, so there's considerably more condensation for the p.c.v system to deal with.
If it's varnished up, you can start to see problems like the one you are describing.
Hopefully, it's still the o.e. metal unit, the aftermarket ones are junk
You can clean it with some carb cleaner.
Just put your finger over one end, and spray a bunch in and shake it. Drain, and repeat untill it clean. You knw it's clean when it "rattles" freely when you shake it. You can gently
blow air thru it from the valve cover side, but don't hammer it with compressed air. you'll damge the sealing surfaces of the shuttle valve inside.
After cleaning it. you can test it by blowing thru it both ways. One way should be blocked, and the other way will pass air somewhat
Probably wouldn't hurt to pull the turbo inlet ducting and clean up any residual oil.
Checking the intercooling piping/core for residual oil and cleaning things up may also help cut down on the smoke.
As for the old guy fawkin with you, dont get mad...
... get even...
zip tie, firmly secured to the driveshaft with the excess tail wrapped around the driveshaft a few times and then taped down with some electrical tape will provide a wtf
moment for the ole geezer out on the freeway when the tape releases at hiway speeds and the tail starts whipping the underbody...
... not that I would know, or anything like that ... disclaimer
GalantVR-4.org will not be responsible for any and all beatings you may or may not recieve for putting that plan into action. Fawkin with a man's car is a slippery slope!
