Hi Paul,

Blue smoke is engine oil.

If you have just changed the engine oil, and you are using the correct grade of oil for the engine, then you can try adding a product called Nulon E10, for worn engines.

It may stop the smoke on startup.

Are you willing to take the intake duct off to see if there is any oil in there?

Hi Paul,

If a Nulon additive has not made any difference, then you need to inspect the ducting to the throttle body for high blowby oil content.

Does it smoke on closed throttle going down hill?

No first blow smoke downhill if take ducting off and find oil what then
Expert:  Gary replied 3 months ago.

Hi Paul,

Probably high crankcase blowby.

Typical of high mileage engines.

Could be time for an engine rebuild.

A air/oil separator type catch can might help.

An air oil seperater what's that
Expert:  Gary replied 3 months ago.

Some engines don't even do that mileage these days.

An air oil separator is a better than average catch can to condense the oil from the blowby gases instead of allowing the oil through into air inlet.

Have you taken any air ducting off thr engine to check for oil in the duct?
