overheating 4M40 engine
November 23, 2010, 12:17 am  from: ahmed
4m40 is a good engine but needs regular careful maintenance. possible reasons for hard start. 1)you need to tune your injectors and injector pump timing 2)turbo seals are gone (and u need to check intake piping for oil), which causes oil to leak into the cylinders giving hard start when cold 3)valve seals are gone leaking oil into the cylinder(combustion chamber) check the compression using a compression gauge to see if your rings are gone...question...is it burning white smoke or blue smoke? what is your oil consumption per 1000km? it should be 1 litre/1000km. Be using castrol oil, it is a bit thick and the viscosity is good. problem in kenya is that no one knows how to tune the turbo and wastegate. 4m40 is a power house and should run cool at most times,except very long uphill roads. and do not be cheated to exchange your engine by the garages in industrial area or ngara, they will mess your car. ...and please dont buy fake parts form kirinyaga road, you will just mess up your engine big time. invest in an EGT gauge, it will save you many problems by giving u early warnings

I changed that troublesome 4m40 engine and put a 5L Toyota Diesel Engine... with the mechanical diesel injector pump. Honestly the thing runs better than the 4m40 only that the 4m40 is more powerful on uphill but the 5L doesnt overheat and is reliably used by the long distance matatus (Toyota Shark). The 5L engine is non turbo but quite good in power and reliability.
I still use the pajero's manual transmission which was combined by some Sikh Engineer in Nakuru. Those cold starts and engine problems u talk about are now a history with the 5L engine.

I need your help concerning my Mitsubishi L200 Warrior-4m40 Engine. Ive had small problems with it lately. The head gasket has been replaced last week. and now am having an issue with the radiator fluid. when am running on highway the temperature rises and fluid from the radiator flows in the expansion tank. The tank is 3/4 full with the fluid. Once the engine has cooled down the fluid is supposed to flow back in the radiator, but it DOESNT. the fluid stays in the expansion tank itself. ive tried replacing the Rad Cap. No use. Kindly help me out please.

I have V46 4M40 2.8 Diesel turbo intercooler for Mitsubishi Pajero, model 1994. I have the problem of the engine. The problem was, when i get started the engine less then 1 minute and continue to drive my car, my engine will suddenly stop after 5-10 minute. So, I need to re-start the engine again and at the end the engine is running Ok. But, I try to do different way method. Start the engine for a few minute,roughly 5-10 minutes and then continue drive my car, should be no problem. Engine,everthing is Ok. I have changed my fuel filter as well. No leaks on the fuel line. Heater resistor from the engine is new. Also performed cleaning into my fuel injector as well. Regularly do service maintenance into my engine. Please advice...

i ve had the same problem with my pajero also. open up the fuel cap from the tank and check out weather the air blows through its periphery. if not clean it or replace it hopefully ur problem will b resolved.

hi guys.. Im using a v32 pajero, year 1997, petrol. Now the carburator start to problem and when driving i only can go around 60 - 70 km/h. I'll try to find a carburator from a half cut, but cannot find it. Can any one suggest me another second option to solve my problem?

And the second thing, if i want to change the engine to diesel turbo, which one model/engine is suitable with? And please advice me about the maintenance for the engine.

Thank you.

I have a 1996 V46 (4M40 engine with turbo). Last month my engine overheated and blew a radiator hose.
I towed the car to Nairobi and had it checked. I have been adviced that it is not wise to overhaul the engine (replace cylinderhead gasket, sleeves and rings) but rather I should get a replacement engine.
Does anyone know where I can get a good engine? (with some form of warranty).
