does any one have any know much about diesel motors as mine has **** it self,has me buggered whats is wrong ,,,sounds like a sick put put boat
thanks
check the fuel filter, its easily removed, most have a primer pump on top to bring the fuel back into the filter before you try and re start.
also if u have a racor fuel filter check for sludge, they have a wingnut setup on the bottom to drain it. Crack the injectors, make sure they are all getting fuel. another problem i`ve come across is a bug that grows in the fuel tanks, u can buy an additive to put in your tank to get rid of it, that means getting a fuel sample tested.(i presume it`s a boat?)
thanks for the advice,fuel filter ok,fuel all good,injectors getting fuel as i replaced fuel pump a week ago and primed injectors,,was running ok with a little loss in lower end power then out of no where started sounding bad ,,towed it home,,,there seems to be a poping sound coming from it ,,has engine compression will turn over but sound weak/bad,rocker cover o0ff all rocker s are fine nothing busted,all belts fine .. it is a delica,,
??????????????
thanks thommo,based on what others have said could be it,how do you tell and or fix it thanks in advance
usually tell when you fist start the motor and it misses, you could try running some inhibitor though the diesel, sometimes that frees it.else you might have to remove the cylinder,
as i sit here covered in oil,grease and crap,will get back inti it 2morro thanks for all the advice,,but now back to my brain surgery course over the net,sort of the same thing but a little easier ,,bummer ya not over this way thommo there's atleast a carton in it for anyone who can get this thing running or onto ebay it goes thanks again
l300 1992 exceed,fuel pump replaced and working,,tried the site been searching ,no luck yet but had some advice ,,so far been told to start pulling it apart that is to get to the cylinder head ,,but i'm not that confident in my skill,,ie i always have parts left over whenever i work on a car
Injectors! Always the first thing to check. After the fuel filter. On Diesel engines you dont usually have a problem with the spark.
timing could be out some degrees i had one isuzu , fly wheel moved 16
degrees on crankshaft made motor run real bad, cost big money to rectify,
crank shaft needed major reworking....best of luck
if its not something bad mentioned already which i hope not!!!
then try what you recently changed!
the injectors and feul pump you recently changed right?
re do it in super clean conditions, see if it works on anything else you did, filter etc.
yes your doing everything twice but it beats trying to rebuild the basterd
go car go~!
It's up and running again,just needs a little fine tuning.
Thanks for all the advice.
what i fixed(with help)was that the rod that holds the rocker arms, at the back had snapped under the screw(couldn't see the break)replaced it, up and running,rocker timing ,fuel pump timing to get right still , not on the road just yet .
so the latest update,had lubemoblie drop in,found i had no compression in 4th cylinder,removed head ,got vsr kit ,had valves checked all seems ok,,took piston out nothing seems to be wrong there,no marks or damaged to be seen ,,so what next?
any ideas?
hanks in advance
Injectors or glowplugs?
try swapping them from a good cylinder and see if that changes which one has bad compression.
Also could be head gasket, but you would change that anyway...
Note I'm not a mechanic.
The compressed gases were going somewhere! Blown head gasket??
My old car had a cylinder liner come loose. That caused a gradual loss of power as it became worse (took maybe a year!). Eventually the gases started escaping into the cooling jacket and pressurised the system enough to split a water hose. Twice. 
) and that's the reading they'd be looking for on the compression tester.
so the latest update,,just found that one of the rocker arm adjusters was different from the others .that is a little longer with a different head,just replaced this and all seems ok now valve wise,,now can anyone tell me how all these parts i have laying around go back together? ,should be fun,anyone want guess how many parts are gunna be left over?,
) and that's the reading they'd be looking for on the compression tester.
No spark plugs on a diesel.
