I have researched and this usually means coolant leak....however,

-Previous had head gasket replaced
-Valve Cover gasket replaced
-Radiator replaced

However the intake manifold "vacuum" tube that goes to the rear ccv valve/elbow was clogged. The stem that screws into the manifold was so full of **** it didnt allow air to pass.

The air filter was soaked to the point of being able to ring it out and it dripped oil. It was clear oil was making its way into the Throttle body, and no air could pass through the filter the filter was like a oil and tar wall.

So I dont know how long this went on(previous owner clueless at best )

Anyways cleaned all the lines and elbow and ran an entire can of sea foam 1/3 at a time into the manifold. Also tossed some carb cleaner through it. Now each time I added sea foam neighbors about called the fire department......I usually after a can had next to now smoke or vastly less in previous experiences.

The idle and throttle response is a million times better with everything cleaned and a new filter. I just still have a good amount of white smoke. I guess could this go away or should at this point I assume its a coolant leak? I dont drive a ton so maybe it just simply needs to be driven more?

Any advice or suggestions?

thanks in advance

I suggest you tell us what year your Jeep is so we can better help you.

 

It's a 1993 Cherokee country 4 door and its 2 wheel drive so about that detail.

 

Clean your throttle body. It's normal maintenance anyway. I guess just drive it and see what happens. More than likely there's a bunch of oil in the exhaust system that still needs to burn out.

The Idle Air Control (IAC) is mounted on the back of the throttle body. (front for 87-90) The valve controls the idle speed of the engine by controlling the amount of air flowing through the air control passage. It consists of a stepper motor that moves a pintle shaped plunger in and out of the air control passage. When the valve plunger is moved in, the air control passage flows more air which raises the idle speed. When the valve plunger is moved out, the air control passage flows less air which lowers the idle speed. Over time and miles, the IAC can get carboned up which can have an adverse affect on idle quality. Cleaning the IAC may restore proper function and is an easy procedure to perform and good preventive maintenance so it is never a bad idea.

CLEANING THE JEEP 4.0 IDLE AIR CONTROL

Remove the air filter cover, associated hoses and the rubber boot that goes from the air filter cover to the throttle body. Remove the IAC with a torx driver (2 bolts; one can be kind of hard to get to)

"Gently" wiggle out the IAC from the throttle body. Gasket on the IAC can be re-used if it is not damaged

Clean the IAC with a spray can of throttle body cleaner; inexpensive and available at any place that sells auto parts. Throttle body cleaner is recommended rather than carburetor cleaner as it is less harsh, safe for throttle body coatings and is best for this task. Use cleaner, a rag and a toothbrush and or Q-Tips. Be gentle; don’t twist or pull on the pintle that protrudes from the IAC as it is fragile and you could damage it.

Thoroughly spray clean and flush where the IAC seats in the throttle body with the same spray cleaner

It is also a good idea to clean the entire throttle body itself, the butterfly valve inside of the throttle body and all associated linkage as long as you have things disassembled

 

Doe it burn/use oil?

 

I'll try clean the tb out specifically. Also there is several leaks in the exhaust hopefully ill fix the exhaust up instead of waiting for all the oil to burn out.

I haven't owned it long enough to really know how much oil it uses there is not a single leak but I do have lifter noise and the oil was fairly low when I got it. Added some but haven't driven even 100 miles since doing so.
