So yesterday my jeep decided it wanted to emmit this whute smoke....well it only happens from takeoff to about 25-30 mph and then stops, but not everytime....seems fairly random so far....any ideas?

 

Like dis?

 

Yes like that

 

With a cloud coming out you should be able to sniff out if its either coolant or oil burning in the combustion chamber. It's got a leak somewhere. If your motor is high-mileage, the pressure from combustion could be pressurizing the case, pushing oil through the PCV into the intake. When you say it's only at take-off, it makes me think that it's probably oil burning.

 

I figured oil but thought to get opinions in the trusty cherokee forum...

 

Upon further investigation I have determined it is not oil, but antifreeze...can anyone tell me the likely culprit? Which gasket needs changing?

 

Head gasket or cracked head. Cross your fingers it's just the gasket.

 

Yeah..worst case I just have to rebuild my original motor sooner then expected

 

Well I replaced the gead gasket and so far so good....seems it was just that

 

fingers crossed. lol
