I have notices some black smoke when I start my 4runner in the mornings, 4cylinder 22re...also, there is some splattering of black condensation that comes out of the exaust...this only happens in the morning, any ideas what could be causing this? thanks

 

is this black condesation oil? or dirty water

 

Hard to tell, but, you can see it on the ground throughout the day. I had a new cyclinder head installed, had this problem before the new cyclinder, and it still continues. Could it have anything to do with the catalyc converter? Thanks

 

im not a mech. but wat about the rings gettin blowby?

 

Could be the rings, the motor has 315000 mile on it, maybe an additive in the oil would help?? What do you think....

 

oil additive might.....

but snake oils rarely fix a problem....if your rings are getting blowby, the thing to do is drive it till its bad enough to warrant repair (when the cost of the oil you are losing is more than the repair) and then do a rebuild on the bottom end.

 

Hope I dont sound dumbfounded, but if it were blowby, wouldnt it be white smoke? This only happens in the morning! Thanks to all that reply!!

 

Generally, not always, but just generally, white smoke either oil being burnt or coolant. Black smoke is, generally, fuel, running too rich.

If the possible cause is fuel being too rich, what would cause that to happen? Thanks

 

check into running an "auto RX" rinse in your motor.. i am not a big fan of putting anything into a motor other than oil but from what i have read and researched i would deff give it a try.. google auto rx

 

Burning rich? Is the check engine light on?

 

how would you adjust a 22re thats running to rich anyway? is there a fuel mixture screw? like on a carb?

 

I highly doubt it. If it is running rich, it may be running hot, or may be running rough, not idling smooth, not reving right, etc. There are any number of things that are signs of running rich, one of the most obvious is black smoke out the tailpipe, and check engine light. Is the check engine light on?

 

try engine restore in the silver can... that stuff WORKS.

 

The check engine light is not on! Thanks

 

Good, pull the codes and let us know what shows up.
