the 255 i just repaired had a push rod adjuster loosen up causing the valve not to open The valve was not opening so no air movement you can loosen the primary fuel lines at pump to see which cly may have a problem
Some pos problems include leaking fuel injectors leaks ,fuel pump leaking main injector pump and crack cly sleave
There are many reasons why a Massey Ferguson 50 won't drive, including a lack of fuel, or a battery problem.
a hole in one of the pistons
the diaphram in the fuel lift pump goes bad and leaks fuel into the engine
Reseal or replace the valve.
Possible causes of fuel in crankcase are: Leaking injector at shutdown, flooding of the engine due to hard starting, defective fuel pressure regulator. A fuel pressure check for drop of fuel pressure at shut down will verify if an injector is leaking. Get this fixed ASAP, and stop driving the car until you do. Fuel in the crankcase will cause severe engine wear and destroy this engine. Change the oil and filter if you have to drive it anywhere for repair.
thats not a question
If it runs fairly normal once it starts and you're getting fuel into the crankcase, it's PROBABLY a leaking injector. After the engine is shut off there is still pressure in the fuel line. If the injector leaks, fuel will drip down into the intake manifold. If a cylinder has an open intake valve, the fuel will leak into there and find it's way into the crankcase.
Your fuel pump is most likely mechanical, check where the fuel pump is bolted to the block and see if the seals have failed, otherwise it can only be massive fuel overconsumption where the excess flows into the crankcase.
it's under the black mesh screen between your feet as your sitting on the machine. you have to remove the gray plastic from the dash to the floor 6 screws per side
this is a term commonly refered to as "making oil" usually the cause of this is faulty fuel injectors, that allow fuel to drip into the combustion chamber the entire time the engine is off. the fuel then seeps past the piston rings directly into the crankcase. there are other ways of fuel entering crankcase, depending on the type of engine. a faulty mechanical fuel pump can also be a way for fuel to enter the crankcase.
