Its All Just Smoke and Misfires! 850 1996

My 96 850T just rolled over 200k! Celebrate, right? Well, unfortunately that is when it all started...

I have smoke at idle. Blue and thicker the longer it idles. No smoke during normal driving or deceleration. (This actually happened gradually over the last few months).

Also, I am now getting codes for misfire in cylinder 3 any time I get on the gas.

The turbo spools well and pulls strong and then the stutter, loss of power and CEL.

Just replaced plugs (gapped properly and replaced due to CEL) and turbo vacuum lines.
The plugs all looked perfect when changed.

Not getting "blowout" through oil dipstick tube and there seems to be vacuum at the oil fill cap. PCV has not been replaced, but I can blow air through the hoses. (Don't want to pull intake if not necessary...)

I theorize: Turbo going south (no play in shaft): PCV system clogged (Possible); AND/OR valve seals or "sticky" valve.


3 kids "helping" + pulling valve cover and cams, etc. = :(
