'00 Odyssey Losing Oil, Very Dirty
I need some help on a perplexing issue with our 2000 Odyssey.
After many trouble-free miles, it has begun losing oil in dramatic
fashion. We've added a 1/2 quart twice in the last 3 days of light
driving alone.
Here's the mystery:
Absolutely no oil on garage floor. Not a drop.
The coolant levels are perfect.
The engine is not overheating or running warm.
Engine acceleration and power are normal.
Besides losing oil, the only other possible symptom is that the oil on
the dipstick is very dirty.
Any suggestions or ideas? Any help is greatly appreciated.

Has the oil ever been changed? If so, how many miles ago?

The times I've seen reports of sudden increases in oil consumption when it
was finally resolved, it was a broken compression ring in one cylinder. I
think it toook teardown to find that; it didn't show up on a compression
test. The catalytic converter burned up the smoke, but oil additives are
hard on the catalyst, too. A look at the spark plugs, looking for evidence
of oil on one insulator, would be a good way to go.

My uncle had a 98 ody bought it used... they replaced the engine at the
dealership due to a porous block. But I doubt that would manifest itself as
quickly as yours.

Check your PCV valve also. It can suck the oil out of your engine and
burn it invisibly. More likely what M Pardee said, though.

While I can't say for certain, I believe the bad cylinder on the $200
Civic is a broken ring and it surely does show on a compressions test.
And that thing is smokin' bad 'nuff to kill mosquitoes especially when
letting off the gas going downhill.

Poor ventilation can certainly increase oil consumption. I remember a
certain F*rd LTD that normally consumed a quart per day increased to
emptying the crankcase in fifteen miles...
Oh... The good ol' days!

depends which ring. oil control rings don't add much to compression,
but they sure do let the oil in if they're dead. a top ring makes a big
difference to compression and not so much to oil.

but they sure do let the oil in if they're dead. a top ring makes a big
difference to compression and not so much to oil.
