Need new engine 1999 Trooper 108000 miles, engine is dead..

Like many high mileage Troopers this burned oil big time. I kept on top of it but still died. What to do now? Will a salvage place buy this with a dead engine? Where can I get a used one?

How did it die? Mine burns oil big time as well, and I have 125K on the clock.

I'm curious... what is big time here??

1qt every 500 miles or so... I've tried absolutely everything: various oil additives, thicker oil, combustion chamber/piston rings cleaner, etc etc... no change whatsoever. What still puzzles me is that spark plugs are clean and show absolutely no signs of oil contamination. And, there is no visible oil leak anywhere.

You must have been burning the oil for ages and thus screwed up the engine. Did you never see blue smoke coming out the tailpipe when you accelerated?

RL (still holding thumbs my 99 Trooper will last for 300 000 miles...)

did you try Mobil 1 15W50??....on our 98 Trooper, it helped the 1 qt every 1300 miles to about 1 qt every 3000 miles.

I then mixed 15W50 (3 qts) with 5W30 (2 qts) and consumption stayed about the same.

Then, I totaled it...:-(

Our "new" 2002 is up to 14,000 miles now...last oil change it used about a half-quart (I think all at once more or less I'm guessing). Just changed the oil before taking off on a vacation trip - towed an 18' travel trailer over 700 miles and didn't use any oil that I could tell. I guess we'll see...I'd like to think I've got a good one that doesn't use much if any oil... :-)

Never. Even had someone tail me and look for smokey exhaust.

I've had this truck for ~30K miles, oil consumption has stayed the same. I guess my only option left is to rebuild the engine... figured out the cost will count for at least 500qts of oil ;) so I'll just keep burning it until rebuild is inevitable

Not that specific one, but I tried 15W40 (can't remember brand now). Made absolutely no difference

If Isuzu engines are indeed prone to seizures (read tales at

then it mayhave been a wise move ;) Yet I hope to keep driving my Trooper for years tocome - one of the best vehicles I've ever owned Peter

I could easily be wrong, but after reading thru those messages, I'm left feeling like half of them are whiney, made up stories. Plus, a good number of them weren't even Troopers (Rodeos, etc), so you're talking about 2-3 different engines, not just the 3.5 v6. Ya never can tell when you find it online... :-)

I sure hope you're right. Most of these sounded like whiners to me as well... "just 15K miles over warranty, and they wouldn't replace it for free!"

Off-topic, most of these manufacturers warranties are crap anyway. I used to own Subaru Forester (warrantied for 60Kkm), and warranty on rear wheel bearings somehow expired in 30Kkms...

Seriously speaking, am I damaging the engine by of burning large amounts of oil?

I'm not a mechanic by any stretch of the imagination, but from what little I do know, I wouldn't think it would hurt anything. I once thought my Dodge Caravan was starting to smoke (turned out it wasn't) but I talked to a mechanic about it (I've got the 3.0v6 that's very common in the older models to wear valve guides and start smoking) and he talked prices, etc. I asked him if it would hurt anything to just keep running until it got really bad, and he said it wouldn't hurt anything, to just keep driving it until it got really bad. Sounds like in the Trooopers, using oil is just a way of life. I know for sure it is in the 3.2's, but I haven't had enough experience or observations to be able to say on the 3.5's. Definitely don't let it get too low though! :-)

From my experience, if you keep the oil level up, it will keep running just fine. I have a 99 Trooper I bought with about 60K mi on it. I quickly discovered that it would burn a quart of oil every 500 miles of normal driving (a quart every 300-400 miles towing my snowmobiles) even using

20w-50 oil, I now have over 95Kmi on it and it still runs great. I had it to the dealer who showed me a service bulletin from Isuzu that claimed that a quart every 1000mi was normal and that consumption could be higher under severe conditions which they said included sustained highway driving? They checked the PCV valve which they said could cause increased consumption if bad, however since the PCV was OK and that I was just out of warranty that I would have to pay to resolve the problem any further. So I have just gotten used to the practice of checking the oil at least every other fillup of gas. So far so good. I would love to know if there is any way to fix this short of a complete engine rebuild. I had a 92 Trooper for over 10 years and 128Kmi and was very happy with it (once I found out about using synthetic oil to get rid of the valve tapping) but don't feel that confidence in the newer one with this oil consumption issue.

Same here. I've had some success with STP oil additive - that one seems to cut oil consumption about 30%. However I suspect the effect is only temporary as I'm still pouring oil into it, and thus displacing the additive. 35K miles and counting... still runs good.

There's one thing I haven't tried so far, and it's complete engine flush. Fairly pricey, though.

what seems to work for me is a combination of 0W-30 synthetic and lucasoil (also synthetic) the lucasoil additive completely silenced the tapping which the synthetic oil alone did not do consumption is also down
