Engine smokes

It only does it when driving down hill. Greyish smoke its a 98. Any ideas?
 
assuming you mean smoke from under the jeep, sounds like a rear main seal leak hitting the front pipe where it crosses the transmission bell housing.

Nope, comes out the exhaust, there is no oil leaking on the ground.

Also, my exhaust runs down the drivers side of the heep.
 
Under compression braking.

I take that back it could also be doing it when accelerating down hill.

Mine does that if i've been sitting in traffic for a while and it gets good and hot......i'll get around to fixing it some day...
 
if you're burning like 1 quart a week, the old-time solution is thicker viscosity oil.

try 50 weight, its summer anyhow.
I tried this on my first engine, it helped a little.
Does lower your gas mileage slightly.

She's a trailer queen, I did change the oil and add a quart of lucas stabilizer. I think it did help a little.

Just wondering if anyone has seen this before.
 
Smoke at high vacuum such as at an idle when hot means bad valve guides/seals. It is even worse going down hill under compression braking.

If it smokes under load, that means shot rings.
 
It's only got abou 90k on it.

I probably don't start it enough.

Starting to sound to me like I need to do a stroker.........
