Hello

I have a '95 4runner and just recently noticed upon start up that it idles rough and has white smoke.

It goes away once it is warmed up and runs smooth.

No water in oil and it does not overheat.

Could it be a clogged fuel injector, valve leak???

Thank You for your responses

 

if you have high mileage, and the engine internals are getting a bit worn, when you have a cold start situation, especially after a period of inactivity, you might have some oil "sneaking by" things like the valve guide seals or the piston rings...i would just keep an eye on the oil level...and if the smoke grows heavier, or smokes for a longer period of time, say, after it is warm, i would find a good mechanic.

 

well showed the problen to my friend, and it is a confirmed dreadful head gasket problem.

opened the oil cap and saw milky/water in oil. must a early stage slight crack on head gasket.

oh well off to the shop it went this morning to another friend who will be working on it.

My 4runner only has 94K orig. miles.
