Question about 1997 Mitsubishi Montero

Open Question

Mitsubishi Pajero NJ 1997 Model

Hi

Just wanted some help. We have recently experienced a blown head gasket in our Pajero. We have since replaced both heads (it is a V6 3.5 litre), replaced the fuel line, fuel filter, spark plugs and now the ignition coils and it still won't start.

Can you give us some help we are going crazy?

SOURCE: Car getting too much fuel at spark plugs

Hello Velma!

It sounds like ther might be an intermittent ignition (spark) problem... when the plugs don't fire, they will get wet with fuel...
So check all of the ignition components, make sure there are no loose connections to the coils are plug wires.

It is also possible that there might be a problem in the fuel injection, such as an injector stuck open and continuously feeding fuel to its cylinder (which would show as only ONE plug being wet), or possibly a bad fuel pressure regulator, letting fuel pressure in the injector rail go too high and causing an over-rich mixture and engine flooding (symptomatic of ALL plugs being wet).

Once the engine is "flooded" it is sometimes hard to "clear" the engine with modern injection systems, but try this: Hold the accelerator to steadily to the floor while cranking --- DO NOT PUMP THE PEDAL! --- This will allow the maximum amount of air to mix with the overage of fuel in the cylinders and help the engine to eliminate the excess without also adding too much back in...

If you still can't get it to fire off doing the above, then remove the fuel pump relay or fuse and repeat the above until the engine tries to run.... It will run briefly until it fuel starves and dies. Then replace whichever you removed and try starting again with fuel delivery back in service.

Velma, I would have answered this sooner, but I've been on a "road trip" and only recently got back home. If you still have problems, please post a comment describing as best you can the situation --- you have to be my eye, ears, nose, and hands in this long distance effort! Also let me know why the head gasket blew, if known... Racing or overheating? If this does help, please remember to rate my assistance --- your approval is my ONLY compensation for providing this help!

Thanks!

SOURCE: We are looking at buying a 1992 Mitsubishi Pajero

It could be other things. White smoke = oil burning
Worn Rings for example?
A compression test would detect worn rings.

Try not to assume an easy fix before you buy it.
Make sure the price is right as white smoke = bad :)

Pajero overheating


It sounds like you had a blown head gasket and it was leaking into the oil or into the exhaust and being burned. if you look at the oil on the dip stick it may look milky. if the head gasket starts leaking internally then it can / will cause overheating

I have just removed a head of a 1992 mitsubishi 6g72 pajero motor expecting to see a blown gasket ??


You are missing the cause, the next step is to PRESSURE TEST the head, a machine shop does that for you. Long story short, something, somewhere is damaged, keep investigating until you find it.

My mitsubishi pajero overheated last night I recently used a solution to repair a blown head gasket it worked perfectly but the vehicle overheated last night please help


Try to check to see if the electric fan is going on or off at the right intervals to keep the engine cool.
Check that the coolant level is high, and the concentration is 50/50 antifreeze to water.
Also, if the coolant system hasn't been backflushed, this may be an option to try to get the coolant passages clear, if they are clogged.

How hot did it get? Did the engine become damaged again?
