Don't panic on that TB, but don't go 40% over the interval like did, either.

It can wait until spring if the pulleys are quiet and the water pump isn't seeping

Thanks, I don't think the water pump is leaking and the pulleys are not loud. I'll get to it in the spring when I can take the bike to work!
So I replaced the pcv system and I'm not sure the oil leaks have stopped. It did pass the glove test this morning after about a 30 minute drive but there was still some smoke coming from the dipstick and oil cap.
I cleaned the heck out of the intake manifold while I had it off and when I first started the car after reassembly, it had a bad misfire that has gradually gotten better (304,305 and 300 codes that have not returned since) but it still shakes a bit more at idle than it ever did. Thoughts?

I had to crank the Hades out of my 1999 after my PCV job - this on a normally starting in 1/3 second car. I think they don't like having the Intake manifold off for some reason.

How old are the ignition parts? Coil cap,rotor wires and plugs?

If you have had a lot of oil on top of the engine, plugs and wires may be oil soaked and need to be replaced.

Switch that turbo to synthetic oil if you aren't using it now. You will sludge much less

Got a p0302 today. Jeez, the wires are from 2007. Guess I'm due. Thanks for the tip. I have been running rotella t6 for many years with good results.

Bougicord only for those wires per the brainpower on this Board. I think I would look at the rest of the ignition parts too.

How about a p0172? Got this code today. Rich condition bank one. Would this be related?

p0172 is almost always a leaky vacuum hose. Is the elbow on the passenger side of the intake manifold, put back in place? That is the most common offender.

ALso not too urgent, wait until Spring. Clear code - see how long it takes to come back.
