i was wondering if smoke coming out the oil cap is normal. Its not a alot just a lil bit real light smoke. Is this normal?

its a b18b engine 1998 integra

 

When you take the oil cap off, or is it smoking with the cap on?

It could be steam from the oil/motor and it's cooling down.

 

when i take it off..

 

In normal operation, there's going to be hot oil vapor trapped under the valve cover.
But if you smell oil burning, that could be a sign of worn valve guides.

If you're getting blue smoke out the tailpipe on startup, that's cause for concern.

 

well it throw smoke from the tail pipe when its cold then it goes away.

 

Blue or white?
Is there a lot of greasy soot on the inside of the exhaust?
Does it ever have trouble starting?

 

its white and only once i noticed that it spit out some black dots. But i dont know if it was water mix with old debri or somthing. And when i start the car it buggles (idles low) and a few seconds later it goes to normal. But it idles ruff.

 

smoke is not that normal. your probably running low on oil or your pcv is not working and the pressure just builds up in your valve cover.


black smoke at tail is sign of rich mixture

blue smoke is a sign that your burning oil

white smoke is a sign of coolant being burned in your combustion chamber.

 

But it dosent smoke all the time only when its cold the thing it dose do is buggle

 

well white smoke when its cold (depending on how cold) can be normal, the black dots your seeing are probably carbon build up running out of the exhaust along with condensation. it probably wouldnt hurt to have a professional fuel injection cleaning done as well as as good throttle body cleaning. Other than that you may also consider and intake manifold gasket...tough call
