Disappearing oil trick?

[usmc81301]

My HMMWV has been running fine no real problems. I go out last night and try to start it and I hear a click and nothing. So I check the batteries to make sure they are ok and they are. So I try to start it again, same thing. I wait for about a minute and try again and it starts, have no more problems for the rest of the night. Go out today and it does the same thing. Then I get it started and it starts smoking bad. I let it run for a minute and it is still smoking so I shut it off. I open the hood check everything and the oil is low again. I just put in a quart and a half oil about 2 weeks ago. I is low about the same or even 2 quarts. Where is it going? I have no oil stains on the ground. Would this cause the excessive smoking? Help Please!!

Sounds like the motor is worn out...Not starting (cranking) is a different problem.

Time for a leak down test. I would suspect bad cable to the starter for the "click" issue. Do the hmmwvs have a starter support bracket on the azz-end? Is it in place?

Thanks for the info. I got worse later and it has a blown head gasket or cracked block. Bad either way.
