#3249 of 3299 Re: oil leaking from somewhere [atfdmike]
Feb 23, 2008 (10:25 am)
I am an original owner of a 2000 Isuzu Trooper, 3.5 SL with 73k miles. I took a long trip last weekend (in the upper Midwest) and added 4qts. of oil 167 miles into the trip b/c my oil light went on after making a stop (I was about 800 miles short of being due for an oil change). I continued another 469 miles and added another 3 qts. I'm taking it in for an oil change today and then have an appt. w/a dealer next wed. for them to do some extensive testing (as I understand from a phone conversation when scheduling the appt.). The service dept. mentioned possibly needing to take apart the engine b/c it is consuming so much oil instead of doing an oil test of 5 check-ups every 500 miles. I also did notice a few drops of oil on my garage floor which I've never seen before. The phrase "taking apart the engine" makes me nervous (being a female in a male dominated auto service world). Should I try your advice of a couple of frequent oil changes and running a product before I take it in? Can I please get your thoughts on all this?

First off, this engine is known to burn SOME oil. I used to loose almost 1 qt. every two to three months. I can tell you what I did to my 2000 trooper (LS 3.5) which may help to remedy your problem. When may Trooper was approximately two years old, I read an online artical on modifying the oil filtering system. The standard oil filter on this vehicle is very small (which creates quite a bit of heat and restricted capacity and circulation). I removed the original threaded oil housing bolt with one I had found on a Trooper Upgrade web-site, which would accomodate a larger filter (Fram type PH8 or any other compatible brand, the same one used on the 2000 Ford Ranger 4.0 litre V6). This more then doubles the size of the oil filter reservoir and increases it's flow. I also use only synthetic (Mobile Gold) oil and extended life (7,500 mile) premium oil filters. I now burn about half the amount of oil prior to the conversion. If you are interested in performing this conversion (you really can do it yourself), I can provide you with some additional info.
#3251 of 3299 Water In Engine Compartment

Got water all over the engine and found moisture in distributor cap. Now distributor cap and rotor are dry. Engine will start but will not allow throttling in order to drive it. If water got into the TBI and fouled the plugs, would this cause this issue?

Hi and welcome to the forum. You don't say what year, model engine and trans your vehicle is equipped with. Kind of hard to supply a good answer. Pretty hard normally to get water that far into intake if you have stock equipped intake system, but it seems a little peculiar that it will start but not respond to the throttles. Your throttle position sensor (if equipped) may have been affected by the water as well. More info will probably get you more or better answers. HTH.

Trooper is a 1990 with the GM 2.8 V6. This one is 4WD with the 5-Spd manual transmission. The intake is the old style breather with the old style ring air filter. The breather covers only the TBI. I just started it again a few minutes ago. It now starts actually better than it has since I got it in Feb 07. Once started it runs pretty smooth. When you depress the accelerator, you can hear it choking itself to death on the fuel if you throttle past 2K RPM. I can smell strong gas fumes from the exhaust when it does this as well. It was powerwashed on Thursday of last week. Not a good idea I know but I had to get some of the oil from the front because I was looking for whatever is leaking so that I could repair it. Anyhow, I thought once it dried out it would straighten up but not the case here. Please help if anyone has any info on what could have caused this from someone else doing the same thing.

jason dont do a half assed job use full synthetic mobile one i have been in very high level race shops for a lot of years and there is nothing that will give you more bang for the buck than mobile one. better gas milage, a ton of miles more longevity all major help to the motor and go with mobile one for the tranny as well. blends are a joke because the part that is not full synthetic just reduces what is to a level of non. if you get my meaning. and there is no other than mobile one. i have seen the results there is no subsitute

Recently my 1999 trooper (automatic, diesel 3.1L) is not working properly. The problem is the gear is shifting smoothly from 1st gear to 3rd gear but was unable to shift to 4th gear. The speed will stay constant at 80km/hrs at 3rd gear. I have consulted a few mechanic, it seem that i'm getting a few opinion for my problem.
My second concerned is what is Torque on Demand? and how it functioned? Is it something link with ABS or ECU? I'm really confuse on this TOD system...Please Help!!!!!!
#3256 of 3299 What is TOD meant for?

I have a 2000 3'.Trooper. TOD allows you to select either 'Power' power down shift (for hills or towing, or a shift up for 'winter' or slippery roads. You can select either (power/winter or neither), by the console switch near the shift lever.

Simply put, it is a traction sensing system. It monitors wheel speed via sensors on the Transfer case, and when is senses a difference in wheel speed between the front and rear wheels, it transfers power to the front axle until speeds match. It is a little more complex than this, but that is the basics, as I understand it.
