I am using about 1qt about every 750 miles.

Leak down test shows 4, 4, 5, 4.

No oil in intake.

Turbo seals dry.

I had a neighbor follow me and he observed blue smoke under hard acceleration and hard deceleration. He said it was not a cloud but definitely noticeable.

Should I be concerned?

Anyone have any thoughts?

Thanks

Does it smoke noticeably on start-up?

Factory manual says up to 1.5 liters per 1000km. you are using half of what they say.

Don't worry unless you see oil under your car.

Hey Darwin,

No smoke on start up.

No smoke reving up to 6k rpm in neutral.

No oil on the ground under car.

Only seeing blue smoke under boost/hard accel.

Thanks

I have a very similar situation ... I am thinking its the oil valve seals ?
I am probably burning even more oil but I do rev pretty high...

If it is valve seals, is a big deal to just leave it and burn oil?

If it is valve seals wouldn't it show blue smoke revving high in neutral?

Bud I wish I knew ....
I have a very similar situation ... That is the only part of the car ( bar only a few others) that I haven't dug into

I thought valve seals were on startup and heavy acceleration was rings or turbo?

fejjj

In my case it is not rings as the compression test and leak down were great.

Rebuilt turbo by Charlie at Evergreen installed about 6 weeks ago.

The only thing left suspect if you can rule out the turbo and rings, would be the head. Altho heads will tend to smoke on startup, after the oil pools around the valves. You can pull the intake after it has been sitting to check the intake valve seals. Some people have pulled the intake to see oil sitting on top.

Will check that in the am.

Thank you

It really is a head scratcher!

You neglected to mention how many miles are in the engine but I would say confidently that it is time for a valve job.
