read this, and follow it to the letter, do as Maywood suggests first. then get a diesel fitter onto it. In section B4 fig 1. it looks like the injector nozzel sits in a cap with seals fitted inside it, did you do a compression test?? what were the readings??

hi aqualbell

no for the test,my mates compression tester was not for diesels it was a petrol only,and they are expensive for me to buy so i`m giving everything else a go to see it it will solve the probs i have in starting the boat.The test will be my last resort.

just another take on the rings,i was told that if i take the oil cap off the engine once the engine is warmed up their be a little bit of smoke coming from it but i thier is allot of smoke then that would suggest that the rings may have gone

i will follow your link that you have sent and let you know how i get on e.t.c

You have gone about it the wrong way, if you do not want advise then do not ask for it!! all of us on here said get the compressions tested first.

 

Just had a word with my mate (diesel fitter) he thinks the compression in the cylinder should be around 300 lbsq inch, give or take, remove all injectors, and test each one in turn note the reading. He is guessing that the rings are gone or the head needs an overhaul. I can give you his number if you wish, PM me.

 

Too much to guess really John. Might just be a simple spill pipe that would take 10 seconds and 50p to fix.

could be Paul but we have been over this ground before, and the fundamental question is still unanswered. Until that is done we are useless to him.

sorry if i rattled you but as said i cannot get hold of a diesel compression tester,i`m not willing to pay ££££ to make one test.I also cannot hire one either!!!

I have not ignored whats been said to be,i was told...sorry advised to get the injectors tested of which i done i was also advised to get new glow plugs of which i have done i was also advised to get a non return valve of which i have done....

 

I'm afraid i have to agree with Aquabell.

Sorry if it sounds a little rude, it's not meant to cause offence. But, if you just fumble about in the dark, not knowing what you are doing, the chances of you fluking a fix without wasting a ton of time and money are extremely remote.

You've obviously spent money overhauling injectors, why not give a local diesel fitter a few quid to pop out and run a quick compression test ?

You could have a word with a local, small garage, or if there is a HGV repair place close to the boat try them. Might also be worth a word with local haulage companies, some will have their own fitters or be able to advise where to go.

The way to fix problems is to find them first, not blindly start fixing things that might be wrong.

hi paul

Thanks for your advise i do know abit about engines and how to bleed them e.t.c i have done this many times before,but the question i asked was that i was not to sure what the silver washers were that sat on the end of the carbon,the reason i asked this question is because the injectors are in now but the engine will not fire up...........whereas it was before i put the injectors in with the washers......it was just i wondered what the washers served as thats all and does it do damage if you dont use them?

I have just read aquabells other post so i will pm him and ask his friend if he`d be able to do the test.......i`d pay him

ps i have also noted about the hgv mechanics....thats a good call.
cheers

 

you are better off using a leakdown tester they are far moreaccurate than a compression tester.

and you normally fit copper washers between the injector and the head, they are a use once washer, cant understand why they gave you steel ones, if they are steel or crome covered copper,

but also check the fuel cut of solenoid if you have one fitted,

 

Why not do what I suggested,just phone or go back to the person who re`coned them,everybody is taken flying guesses,I have 20 years experience working on Diesel engines,(but not the modern ones with all the sensors) if it will not start it is either not getting fuel so if it was running before you got the injectors re`coned that is the problem,a diesel engine will start no matter what state the rings are in,stands to reason as I pointed out if it was running before,it can only be injectors that are the problem,possible it may be another fault but for my money,back to the shop and let him look and test them.

hi

thanks for your help.
fuel cut off solenoid?
The boat did run ok infact the it would run for hours without missing a beat it was just that it took a fair bit of time to start even when warm that is why i have replaced bits and pieces to see if this will solve the problem.

my injectors came with the new copper washers that you mention but they also came with these silver/chrome washers (of which i have never seen before) they are very small in size,well about the size of the tip of the injector.Basically the end of the injectors has a small point and the silver washers fit over them.

Hi pat

I am going to ring the fellow who serviced them and see what he seys and also find out the name of those silver/chrome washers.

watch this space

 

The silver /chrome washers if they are corrogated are heat shields to protect the injector nozzel have been fitting these for years.

IAN

 

I have just come off the phone to the diesel mechanic he has told me the washers that go on the end of the injectors are called heat shield protectors,he also said the only part of the injector that should take the heat of the combustion is the tip of the injector ( hence the heat shield) he advised me that the original ones should of had them on but they did not,i also asked about removing them but he said that once its been started things should be fine

He said that what i basically know,is that aslong as the diesel is getting through clean and without air the boat should start and maybe its just a case of because i have taken the injectors out and also cleaned the lift pump thats why it MAY take abit more time to start but once it starts it should be fine.

also the stop on the boat it working fine so no probs with that either

Lift pump ?, have you primed it to see if it is pumping ok as you did not mention that.

yes the lift pump has been primed,it works fine i took the diaphram (sp) out and cleaned it as it had a lot of crap in it,it went back the same way it came out.The only thing that may cause me probs is that i did not replace the old coppers washers i put the old ones back in......not to sure if this is that important?

Altho when i get to the boat this weekend i will buy 2 new ones just to iliminate maybe a problem

I bled from the lift pump to the main pump( removing the little screw to let any air out) and then to the diesel fliter and l left all 4 injector tubes open untill i got a decent amount of fuel coming through them and then i connected all 4 injectors,i did 3 up tight whilst i left the 4th injector abit loose so as to remove any air that may have been getting in,i then tuned the engine over a number of times and made sure no air was in the system and then locked off the 4th injector......sadly it still would not start,so maybe the 2 x copper washers do need replacing or maybe abit more time trying to start it may remedy the problem.

Seems to me you have done everything correct,may i sugest that you get a fitter to just check the pump timeing,as you mentioned it is a bad starter even when hot,possible the timeing has slipped bak a touch. Pat

hi pat

Aquabell has given me the number to a diesel mechanic and i intend to ring him over the weekend,i will see if he wants to
a: check my compression rings
b:look at the pump times e.t.c

I am hoping its maybe just the timing as that`s an easier option as to replacing rings e.t.c but who knows it could be something else.

 

Just an update as to how i got on.............could not start the boat,this was due to worn ring gear,i took the starter off to check the teeth on the ring gear....the ring gear have a lead in but they are very worn and when you crank it over it makes a very horrible noise and grinds.

I have sourced some ring gear for £32 so now i have more work to do....jeez dont know why bother with boats.

 

Know that feeling mate. We all feel like that when they are giving us grief.

Hi paul.

just won a 1.5 bmc on ebay for £62 so i will take the flywheel and the starter and pump off of this....well i`may even use this and get mine sorted in when i have the time and money and maybe in a better frame of mind.I know i have taken a gamble buying an engine that i have not seen running yet but just for the spares to me its worth it............... i hope:shutup:
