I've got an 88 3.2 with about 131k miles. I recently had a 15k mile service done with filters, plugs, oil, and valve adjustment done. Prior to the service, i really had no issue with smoke beyond a little puff at startup here and there. Since the service, I've got and increasing amount during operation, mostly during deceleration and some at idle. My mechanic claims it's likely the valve guides which seems to be the common answer for smoke during decel. I find the timing a little suspect, that it'd start showing itself right after the servicing. So my question, is there anything that could've been done during the valve adjustment that could be the cause of this?

I believe the car is running a little rich since the service. When I first got it back, upon start up as it was doing the gradual drop from about 1200rpm, the idle would surge about 1k rpm a couple times before settling at about 800-900 rpm. It would also occasionally dip significantly or even stall after pulling off the accelerator after my first touch of it. The surging has stopped. The stalling is very rare now.

It's been almost 3 months since the service and about 2200 miles. I haven't tallied oil consumption during this time as it didn't seem out of the ordinary, I don't think I've put more than 3 quarts in.

Some history on the car:
I've owned the car about 2 years and put about 10k miles on it, it's been really healthy during this time. Previous owner had kept good records and spared no expense. No top end done though. I had a PPI done before purchase, compression on all cylinders was 125psi, and leak down 6%-8% between all cylinders.

Any thoughts would be appreciated. I know this is a common topic here. My mechanic is usually good, but there have been multiple times where he's missed the mark. I guess I'm just trying to find out if this could be the result of something he did or didn't do, or if it's just coincidental timing of expected wear.
