The injectors are leaking. G.M. had alot of problems with leaking injectors. Not real sure but it might have been a recall. You can ask G.M. dealership if it was a recall.

    The fuel is under extreme pressure. When you turn off the engine the fuel remains under pressure. The injectors leak just enough to bleed the pressure off, The fuel goes past the rings into the crankcase. Basically the injectors leak when the engine is not running.

My year 2000 diesel escort van wont turn over


sounds like cylinders are full of diesel you need to pull injectors to relieve pressure on cylinder.. it causes it to lock the engine up .. you might have left the key on with a leaking injector and filled the cylinder with diesel and then it would lock you engine.

I put petrol in my diesel car


If you accidentally put petrol into your diesel car there is an unbelievably easy fix for it.
firstly get a paper coffee/tea cup(sold in most garages) fill it with any type of engine oil and add it to your diesel tank.(apply it in two half-cup measures and you will not spill it everywhere), then fill your tank with diesel. your engine might splutter a bit but the engine oil will compensate for the petrol and it should correct its self. Do this again the next time your tank will take a few gallon of diesel and it should be fine.

Intercooler and EGR problem


Sometimes people get this low power and smoke problem in a turbodiesel car with an intercooler. Once it is not your injectors or turbo gone, you can solve it without buying new intercooler or EGR valve. You can actually clean them. It does take few hours of your time but cost you much less. All you need is few hours of time, a gallon (4-5liters) of diesel and same of petrol (better naphta but its hard to get in some places). First you need to take of the intercooler which might involve removing front bumper in some cars. Once you have it out, put it on the ground (do not damage the core) and fill it up with diesel. Cover the inlet and outlet (best with balloons) and leave it for few hours. Meantime you can take care of the EGR valve and inlet manifold. Using petrol and soft brush clean all visible parts but do not fill EGR with petrol too much as it must be complete dry before you put it back. Do same with the inlet manifold, just clean that oil/smoke build up. It is slagish but getting rid of it will add your engine extra kW/Bhp and some life to it. When you finish cleaning and drying the EGR and manifold your intercooler should have been a little "washed" by the diesel inside, shake it a little bit, the "balloons" should stop the diesel from spilling out, and leave it for 2-3 hours. After that time empty the diesel out of it and fill it with petrol (naphta) to wash out remainings of dirt and diesel, do it couple of times while shaking until the liquid is more cleaner, than dry the inner of the intercooler, make sure it is completely dry and as clean as possible as anything that will be wet with diesel may cause some serious problem. After drying and putting everything back, leave it for a while before starting the engine, this is to make sure that whatever remained undry will vapourize. Remember when you start the engine do not rev it up just leave it at idle for 10-20 minutes. This will add temperature that will dry up anything you've missed and not cause any damage as there will be not enough pressure. After this operation you will notice a change in the car's performance.

You would be better off putting everclear alcohol in the system. Rubbing alcohol has no effect on the water content and may destroy the seals and gaskets in the fuel system. 100 percent ethanol. mixed in with the diesel.

ISUZU HAS A RECALL ON LEAKY INJECTORS ON THAT TRUCK GIVE THEM A CALL The injectors use the engine oil at very high pressure to inject the fuel, and semi synth oil just can't withstand these high pressures for very long. It breaks down, loses it's viscosity, and then the injectors won't work properly.
Change the oil to fully synth, and you should see a huge difference. (Do both oil filters while you're at it too).
1. Injectors. Usually the electronics in them fail and cause a miss fire.

2. Injector Sleeves. Causing diesel to leak into the sump and in severe cases the oil/diesel mixture filling up to such an extent that the vehicle actually runs on its own, on the mixture. This can cause the engine to rev to the maximum until all the oil/diesel mixture is burned or the engine basically destroys itself.

3. Rail Pressure Sensor. If the E.C.U cant determine what pressure is at the rail the vehicle may not start or stop running . A fairly simple fix with only the rocker cover needing to come off.

4. Rail Pressure Control Valve. This controls the pressure supplied to the rail. Engine will not start if this control valve is faulty.

5. Turbocharger. A very unreliable unit. Seals usually go after 50000miles.

6. Dual Mass Flywheel. Seldom give trouble but I have seen a few that have. If the new flywheel is taken off and not put back in the same way as the old one (lined up via a half moon shaped mark) the engine will not start as the flywheel sensor will be unable to determine the position of the flywheel.

7. Throttle Position Sensor. Fairly troublesome. Usually no deteriation in driveability but will bring on the engine light.

The engine is a gem when running correctly but unfortunately its a rare occurrence. I think the 02 onwards models had a lot of modifications done to them such as improved injectors etc.

you must fill the fuel filter housing with diesel to eliminate air pocket. if you don't have diesel, fill it with automatic transmission fluid. it will smoke for a few seconds, but it will run so fuel pump can catch up. don't touch throttle for a few seconds till you know that it is running on diesel and the tranny fluid is all used up.
