Engine recalls for the 1994 Isuzu Trooper

Engine

94V132000122,297 vehicles affected

The problem
Constant expansion and contraction of the cylinder head causes the camshaft seal end plug can become dislodged from the cylinder head. This allows oil to leak from the camshaft.
The risk
This can cause engine damage and possible engine fire from oil leaking onto the hot exhaust system.
The fix
Dealers will install camshaft end seal plug retainer plates.

firemen opened the hood and then they opened the drivers door and then another fire started in the drivers floorboard coming throughout the firewall. They put that out. They asked if we were driving it but it had been turned off for at least 30 to 40 minutes. The truck was parked next to our house under a car port with both of our kids in the house and at with cars in front of it. The truck was running so good didn't have any problems. I read that there was a recall that's similar which is 94v132000 but isuzu said it wasn't the same so it was my problem. We only have liability insurance. There is nothing left inside the engine compartment besides the main engine. Everything else was burned and fell out. *Jb

The engine was burning a significant amount of oil, so I took the vehicle to the local isuzu dealer to be inspected. The chief mechanic told me that there was a material failure in the piston rings causing the engine to burn the oil. I called isuzu usa directly and asked for assistance. I was told that there was nothing they could do, even though one of their mechanics diagnosed a "material failure" in the engine component. I have since spoken with other mechanic who have stated that this is a "common problem" with troopers. Any assistance would be appreciated.

My car suffered from the smell of rotten eggs from the exhaust system whenever stopping the vehicle. The dealer replaced the oxygen sensor 1st. A "cracked" vacuum hose 2nd. All 6 fuel injectors & spark plugs 3rd try. They then blamed it on the oxygenated fuels we have in california. It still stinks like crazy when coming to a stop or parking after driving it. It made my wife sick on a number of occasions, but they stated that there was nothing else they could do to correct the problem. My air conditioner had...

leaked it's freon out 3 times before I demanded (and paid for) a leak test that revealed multiple leaks. Although warranty expired I demanded repairs due to the history of problems. They replaced expansion valve, receiver dryer, gaskets & o-rings. The compressor failed in less than 2 weeks. I had to go to battle with them again to get that problem corrected. I imagine they realized the documented history by now, so they replaced the compressor at no charge. *Ak
