loosing oil in my truck

How much, over what period of time?

Mine too and it hasn't been rebuilt. Only 77k miles on it (97 1500) Loses

1-½ to 2 quarts in 3000~4000 miles (between oil changes). No drips on the floor, no smoke on startup, no smoke on acceleration, not showing up in the cooling system (thank God), just magically disappearing. It's obviously burning it, but slow enough not to be visible in the exhaust. Tailpipe residue, what little there is of it, it is a light grey. This is also not something new for this truck, it's used oil almost since the truck was new.

I thought valve guides possibly, but if that were the case it'd blow a blue cloud at morning startup. And morning starts are clear. Compression check didn't lend any clues either. Plugs are clean. I've had some frustrating history of P0307 misfires for about a year, but the wire rerouting TSB seems to have addressed that, for the time being anyway. Knock on wood.

I guess I shouldn't bitch. It's been a good reliable truck and so far has never stranded me. Chews up front tires if you don't rotate every-other oil change and piss-poor fuel economy, but not many full-size gas powered V8 trucks do much better. Sure as hell glad I didn't buy a Chevy or a Ford.

Ever check for a leaking plenum gasket?

I had a 3.0 dodge that used 1 liter every 1500Km - and it never showed even a whisp of smoke from the exhaust. The valve guides were so loose I was surprised it was not using a whole lot more. It DID kill the cat.

Incidentally, it's spelled losing, not loosing. Don't flame me I'm just passing along the data. If no one says anything no one will ever know. Clay
