Blue smoke on accel = valve seals?

[NaterGator]

Another thread from me, oh joy

I had to get dropped off for an internship down in Miami which meant letting another person drive my cruiser away from me

We sat around waiting for the limo with the car idling, and then when it finally came Nicole drove away in my car. She passed through some sunlight right as she was first accelerating and I saw (for the first time as I'm never behind my cruiser when it is moving ) a decent bit of blue smoke from the tailpipe

So I know I'm burning oil on acceleration and a cursory search points to valve seals. My PCV valve was replaced when I did my valve cover gasket about a year ago, so I doubt it's the valve. Does it seem reasonable that a 130k mile cruiser would have leaky valve seals? And would this show upon acceleration?

I'm beginning to wonder if this explains my somewhat high oil consumption and perhaps could shed insight into why I have the classic pinging off idle (burning oil = carbon deposits in the cylinder)

No time to pull the head right now and do the HG (I've only got about 2 weeks in may before I have to head to NC for work) so I'm considering just living with the burning oil until I have time to PM the HG or it just goes by itself.


I'm just kinda surprised to see a 130k mile 1FZ with leaky valve seals.

My past experience, Blue smoke on startup is valve seals.
Blue smoke on acceleration is oil control rings. Might want to check compression or do blow down test. Although I haven't heard of a case where an 80 needed piston rings.

blue on decel and start up is valve stem seals.
blue acel is pistol rings.

Well I'll just assume for now that it was running a bit rich and the smoke was black (fuel) but looked blue from being cast through the sun (like looking at a sunset through campfire smoke) and do a compression test when I get home. I'm not expecting to find anything out of the ordinary (not down on power, shouldn't have any reason to be eating piston rings) but you never know

What did you find?
