Intermittent blue smoke...

[cation]

I've had my S14 for about a month and a half now. It has about 163k miles and runs strong. I've noticed, however, that on occasion it will emit a puff of blue smoke when taking off from a stop light. I've burned through about a quart of oil over the course of the last 3000mi.

I've done a compression check and I'm seeing an even 190 across all cylinders.

The thought of valve seals crossed my mind, but when I decelerate hard from like 6k rpm down to 3k rpm in 2nd gear I do not notice any smoke at all! Even when it will puff at stop lights...

I may go an entire week without any puffs, but then some days it'll do it.

It never smokes at cruising speed.

Anyone ever experience this?

I'm thinking a semi plugged PCV system whose valve sticks on occasion is leading to my intermittent blue smoke puffs... That or a gummed up piston ring that gets stuck in its land from time to time...

I plan on running some Seafoam through my crankcase before I change the oil tomorrow or Friday to see if that helps at all.

Any ideas/suggestions?

Thanks!

Oil ring lands, and valve stem seals.. 160,000 miles sounds about right for that

My KA ran like a bear but drank a quart every week.

Its most likely the pistons oil ring lands are wearing out. If it were valve stem seals, it'd blow a puff of smoke every time you started the car after it sat for a while. reason being is oil pools in the head while not running, and then as soon as you turn the car on that oil gets sucked past the seals and is burned off. It will still burn oil that way while driving but so minute you wouldn't see it until after you turned the car off for awhile again.
