fuel problem on m1009

[68impalass]

Picked up my first MV in a number of years.(M1009) Got it home, did the usual stuff, changed oil, fuel lines, filters. It runs great but after I shut it off about 4 or 5 tablespoons of diesel fuel drips out of the vent hole on the flywheel cover. Its fine when it's running, no leak. I checked all injectors, bypass hoses, the valley under the injector pump is dry. PLEASE give me some direction here!!! (this is my first diesel) and thanks. Oh, I took the flywheel cover off and I cannot see up high enough to see where its coming from. It's definitely diesel.

check the area around the fuel filter on the firewall, its coming from the top of the engine, not inside the bellhousing.

I will check this area one more time this evening, thanks for the info.

Check the throttle shaft seals on the IP as it will drain down the intake valley and come right down the back of the engine right in the area you are talking about.

There's even a little hole in the rear web of the block to let anything in the valley run out and down the back of the engine.

You might have to remove the intake manifold to get at the IP. Check the fuel supply line going into the back of it. It might be leaking. At any rate, you can run your engine (for short periods of time for diagnostics) with the intake manifold removed. You can watch the IP and the valley of the engine that way, looking for the elusive leak.

thank you guys very much. Seems it sure is the throttle shaft on the IP. Funny it only leaks when the engine is shut down. The guys at Lakehurst were great during loadout by the way!!
