1995.5 burning lots of oil

Hey, everyone.

Last August I bought my first Isuzu, a Rodeo with 87,000. After a month I noticed I was losing a lot of oil. Nothing was dripping, so I assumed burning. It's obvious that's the problem. I see smoke coming out the tailpipe on colder days until the engine really gets heated up. If I'm on the freeway a lot I can lose up to a quart in two weeks. Pretty disgusting. Does anyone have any experience with this problem? I'm pushing 96,000 now and everything else runs beautifully without any loss of power.

I had a high view of Isuzus before I bought one, but this is a bad first experience, one I hope is just a fluke. I'll appreciate your thoughts.

Thanks.

I have had two Rodeos, 1996 and 1993, with the V6, the first was worse than the second when it came to using oil. The problem is with the intake valve seals. These units have 24 valves, with 12 for the intake. When these seals wear out the oil on the valve stems is sucked into the combustion chamber. The best fix is to have a fresh set of seals installed. The next best is to try and swell the seals with some of that high miler motor oil. My 1996 used a quart every 1000 miles.
The 1993, that I use as a work car, uses about a quart every 3000 miles. The 1993 has 130K and I use the high miler oil from Quaker State.
Yours is not the only Isuzu that uses oil. At a couple of bucks a quart, it is still a good rig.

The "smoke" on cold days is normal. It's just condensation. Kinda like when you can see your breath. Also, if your seeing blue smoke while driving, that usually indicates worn piston rings, not valve seals.

When I bought my new Rodeo in '99, I also noticed after a few months that is burning more oil than other cars I've had. After checking some forums, people were saying that this is normal with this car. So if this is your only problem, then don't spend your money fixing te engine because it was doing it when it was brand new, aparently it's a design issue. If there's more then just oil consumption, you may consider fixing it.
