Hi guys I'm at the end of my tether and really was hoping to get my engine
going but may have to consider getting another. I've asked mechanics and mates but no luck.. If anyone has ideas please share.
: perkins 4.108
The symptom thus far is obvious and repeats, it starts (with a tiny squirt of easy start) and catches and revs like hell (started with full throttle) and dies quite quickly ( in less than a minute ). Im not an expert, but it sounds like a fuel
problem as if being starved.
I have bled it more times than i can count,
Filter is new
opened lift pump
and see no damage or block
have cracked hp feed to injectors and turned over - clear drips of fuel
have taken injectors out turned them upside down and cranked - good atomisation on two, a bit of a 'thicker' spray on the other two.
about two weeks ago i did have it running for about 2 minutes.
A bit of background : Its a 2009 rebuild
. I've lived aboard for the last 3 years 2 of which the boat
wasnt mine, in that time the engine was never started and I've heard that the previous owner hadnt started it either. When i began working on it it was quite difficult to turn by hand but I eventually got it and now it turns easily (despite a squeaking sound like rubber squeezing**). I cleaned the heat exchanger
the fresh water pump
and gave the sea water pump
a new impeller. I found an old receipt (2014) form a diesel engineer
saying that the injectors were serviced and the injector pump
as well - that it was clogged with stale fuel. When bleeding I sheared the screw on the top of the pump
on the governor/anti stall device - which i replaced incl. the anti stall device - currently not set (I've been told that this should not affect the running of the engine and that it is set after the idle is set, and that it prevents stall after sudden deceleration).
Another thing I noticed - the stop lever that is on the DPA injector pump
when pulled, the one time i tried, did not stop the engine - i have made sure it is all the way to the run position - perhaps its stuck inside ?
** The squeak wasnt there before I accidentally flooded the block with sea water
by cranking with the seacock open. I took the exhaust
maifold off, the injectors out and turned over plenty of times, then poured about 300ml of oil
down each injector hole and turned over many more times. I've had it start since that episode but again the same thing happens.
Thanks for any suggestions, after just being told that my I may need a whole new rig and mast
I would love not to add an engine to the list !!
