Diesel in sump

[simbo030358]

I have in my boat 2.4 ford transit engine which is producing loads of white smoke, I have removed the injectors and one of the sealing washers at the base of the injector is very worn, could this be causing the fuel in the sump and the white smoke ?. It starts from cold, but if its been running and warm and then switched off in a lock
it wont start it seems that the engine is locked, but when left it will start.
Any help please.

Sounds like you have an injector seized open pumping neat fuel into the cylinder causing a hydraulic lock when engine shutdown, run the engine and slacken off each injector pipe in turn untill you have 1 cylinder that makes no difference in engine sound, it will be that one thats faulty.

The white smoke is unatomised fuel just burning in the cylinder and exhaust.

I had exactly the same symptoms - on a brand new engine! And the cause proved to be exactly as suggested by volvopaul. Another possible cause, however, is a hole in the lift-pump diaphragm. A small hole will still enable the pump to supply sufficient fuel to the injector pump whilst sending a steady stream into the sump!!

Cheap to test and fix

Most large towns will have a outfit that specialises in diesel servicing/reconditioning injectors and pumps.Normally hidden away up some back street or out on some trading estate.Yellow pages worth a look,if all else fails,find a taxi rank,look for the the most ancient cab on the rank and ask where the bloke who services his car gets stuff fixed.
A new injector weeping into sump,was the cause of problem recently solved,when oil pressure on a newly rebuilt 6 cyl Ford lump dropped off dramaticaly when warm because of oil diluted by diesel.
Problem only found after a couple of strip downs to check oil pump wear/leaks in pick up pipe etc.............

Very common on the Dover engine. Keeping an eye out for a suddenly rising oil level or even a static one depending on how much oil she normally burns is the way to go.
Had a couple of runaways because of this problem on trucks that put cones out on the motorway.
Hate motors with injectors inside the rocker cover, one weeping leakoff or injector union later and its diesel in the sump time.
