1993 Explorer - oil problems

I recently bought a used 1993 explorer (160,000 miles) and the person that I bought it from says that for the past several years, they've had to add oil every 1,000 miles. They had mechanics look at it and nobody can explain why it's eating so much oil (it's not leaking out). Has anyone heard or have experience with this?

This is my first post...so I apologize if this has already been discussed several times !!

Any input is appreciated !!

If it's not leaking, then it must either be going out the tailpipe or into the cooling system. Have they checked for signs of a blown head gasket? Also, check the PCV valve. With 160k having to add a qt every 1000 miles isn't the worst thing in the world, especially if it's not leaving spots or smoking real bad.

Probably you need new valve stem seals. Not too hard to replace IMO.

A puff of blue smoke at start-up perhaps?

I would change the pcv valve first and see if there is an improvement. It's not like you are in big trouble.

Had one doing that and it was weeping oil into the lower intake manifold, fixed that and away went all the other vacuum and fluid leaks.... 2.5-3hrs to change out the valley gasket.
