help, i have recently bought a 2001 isuzu trooper and it uses alot of oil!! it doesn't leak oil?

Question

isuzu trooper 2001 that burns oil. does not leak oil. 3.5 liter engine i have talked to 2 mechanics who say this seems to be a common problem in this make and year and the problem is not always apparent when they do an engine teardown. isuzu claims this not to be the case? anyone out there with a similiar problem have an answer or suggestion for me?

Answer 1

Your information is correct; there IS a problem with this engine. Isuzu has a vested interest, so of course they aren't going to admit to anything.
If the engine has been warm (over-heated) even for just a little while, or if the maintenance has been postponed or unreasonably extended, this engine DOES consume oil.
The only thing you can do for it is to raise the oil viscosity index, and use an oil for high mileage cars.
It won't stop it, but it will slow it down just a little.
As far as the remedy for you,--- you have really two options.
1) Replace the engine (crate)
Don't wast your money on rebuilding this one, by the time you pay for the labor to rebuild it, you can pretty near pay for a new one, and it comes with a warranty, wheraeas if you rebuild the old engine, if the mechanic misses just one little detail, you may wind up with further problems. A good mechanic and shop will stand behind their work, but not for a full 2 years, and besides, you will have do to without your car again while repairs are made.
2) Use this car for a trade-in for another or new vehicle. You don't really need these headaches, nor in today's world have to wonder how long your car is going to be dependable.

Good Luck

Answer 2

when you start the car up after it has set for awhile, what is the color of the smoke (if any) comes out of the tailpipe? what color(if any) comes out of the tail pipe when it is in operation?
