1998 Isuzu Trooper Owner Comments

problem #4

Jan 152006

Trooper 4WD 6-cyl

  • Automatic transmission
  • miles


I have a 1998 Isuzu Trooper with a 3.5L motor and it eats motors oil like no other. It does it everytime I have changed the oil since after about 50K miles. The motor consumes roughly 1qt of oil every 1000 miles, even after a recent oil change. I have looked on countless web sites and forums all over and this is a very common problem. People just do not know about this web site and what you do. This problem will persist and eventually end up in engine failure and can be a very costly problem. Thousands of dollars later and a new motor, one will still have this problem for there is no way to fix it. The drain back holes in the oils rings is what I have been told the problem is. Please contact Isuzu about this problem and have then do a recall please! it would save a lot of money for everyone who drives a 3.5L Isuzu/Acura motor.
