Question about 1991 Mitsubishi Mighty Max
Hi! Im Venz, I want to know what is the cause and the solution for my pajero 1991 model with 4d56 engine. Every morning it is very hard to start the engine i check the battery is in good condition. What should be the cause of this problem? Another 1 is the engine oil that drops under the bell housing i replace already the oil seal there but still there is leaking, and i fix the half moon also but still leaking. I cant determined the cause of leaking. Can I ask some advise to my problem? Thanks a lot in advance.
You should check that you are getting power to your glowplug busbar. (thats the alloy bar that connects the power to all the glowplugs).
1.Get a circuit tester and connect the clip to negative earth -
2.Get someone to turn the ignition key to "on" while you hold the tester on the busbar. It should light up for around six seconds I think.
3. If this happens all good than the next step is to check that the glow plugs are turning off correctly while your driving or operating the vehicle.
Also remove and inspect the glowplugs they should be just a nice brown/carbon colour...
They should have no chips out of them or damage of any kind.
These 4D56 engines have a glowplug timer that almost always stuffs out. Then they cause the glowplugs to stay on almost the whole time while driving which stuffs them quickly...
Let me no how you get on
I have a few easy ways to fix this problem!!!
