The first start of the day produces blue smoke & tons of it like the engine has just been sea-foamed. It usually only last a minute or two, then stops. The rest of the day no smoke is present on short stop overs or under hard acceleration. Let the car set for 5 to 6 hours or more & the smoke appears on start up again. I assume this is valve guide seals leaking. Any other ideas?

 

you should clear the smurfs out of your engine, get gargamel, he'll do it for free

Sorry no usefull information from me

 

If it's blue on startup then I would guess it's a valve guide leaking as well.... Possible it's a ring but I doubt it.... Are you losing or burning much or any oil between oil changes?

 

High manifold vacuum will pull more oil through a leaky valve-stem seal.

So you can shift to a lower gear& take your foot off the gas completely (engine-braking). Have someone follow & watch for the blue smoke to increase under that condition to confirm.

 

It has almost stopped smoking on start up, but it does puff smoke when engine braking. I am just suprised that it has almost stopped smoking on start up--I did add a a quart of Lucas on the last oil change.
