white smoke (kinda blue) coming out from the right ((exhaust)) only&#3


Recommended Posts

Good Day,

C2 1998 190k miles

It's been noticed the last few days a white smoke (kinda blue) coming out from the right ((exhaust)) only! that does only occurs early morning around 1 min when turning on the car or when it is left parked for a long time (five hours or more).

To take in consideration the valve seals Has been changed and head gaskets In less than a year.

I think ( maybe ) this only occur when the type of oil changed To titan supersyn 5w40

I checked the water level and oil level they are normal all the times. Also there is no water showing in the oil.

Your help is appreciated

Best Regards,

A little puff of smoke is not unusual if the car has been sitting for a while, due to the occurrence of oil leaking past rings/seals in the horizontal cylinder configuration. If the smoke persists beyond the initial start-up that would indicate a problem. Perhaps valve seals, valve guides, rings, and/or cylinder ovality.

If you noticed this happening after an oil change, perhaps try a recommended/sanctioned oil at the next fill and see if it persists.

Hi, I had similar issue. I replaced AOS and no more smoke. I have video of pre and post AOS change if you want to compare to what you're seeing. PM me your email address and I'll send.

Typically an AOS failure will exhibit smoke out of both tailpipes, because of the failure method, the oil is burned/distributed evenly between both banks via the intake.

In the case of blue smoke in one tailpipe, more likely related to oil in combustion due to one of the methods I mentioned in my previous post.

It would be a good idea to do a leak down and compression test in bank 1.
