I've had around 10 vehicles, purchased all from private sellers, and of course this is the time I somehow forget to check the oil before I buy the jeep. I checked the oil level and there was NONE on the dipstick. I then drained the oil to see how much was actually in there; turned out to be 1.5 qts or so. Awesome, huh? So I put 5 qts in and started it up, lots of white smoke came out and some water dripped from the tailpipe. I'm guessing this means I have a blown head gasket and there is oil being burned in the piston cylinder? Might there be some other reason? I should also mention that after I started it up I drove it about 2 miles and came back and no more white smoke. I'm about to go for another ride to see if it comes back after I let it cool (I believe the thermal contraction of the fluids might pull some more oil back in if there is a leak). Any ideas/input?
Sorry, it's a 99 V8 WJ. By pan do you mean oil pan? I did notice it looked a little oiled around where the oil pan meets whatever it's mounted to but it wasn't wet by any means. Can't imagine the 4qts leaking out there. Plus the oil filter looked new and is why I'm baffled. Although, with the things I've been finding I wouldn't be surprised if he just changed the filter to make it look like it had been well maintained. What a ****.
Could be worn valves or rings if the PO kept it that low for any signifcant amount of time. Keep an eye on it for a week or so, then if problems still are present have a compression test done.
After the initial cloud of smoke and condensation drip from the exhaust I haven't had any problems. Amazing what taking care of your vehicle will do. When I got this jeep it had a shifting problem (speed output sensor fixed that), a leaking radiator of about 60 drops per minute (alumasealed it, no leaks), vibrating during high speeds/stopping (replaced rotors) and a heater core problem which will not be so easily solved but still a cheap fix. Paid $2k for the Jeep and will have fixed everything for about $250. Wahoo.
