[perkins engine]

thanks to you all after all the trouble i had with the 4108 with diesel constantly filling up the sump.

this was resolved with the advice i gained from all your response we fitted a new lift pump and also a new injector pump

the differance in engine noise and quality was like climbing onto a new boat no more shouting and the boat seems calmer almost tranquil

so heres a big hearty thanks especially to colin and jill for puting us in touch with a very helpfull site from us to all who read this

thanks for your help and kind offers of free fitting of lift pump etc its nice to no the boating world has like minded people.

it filled the engine bay with 12litres of oil/diesel mix first time ive given her 3 oil changes and monitor her running for 3 quarters of an hr at a time hence catching her early and reporting it again to mechanic i will say all he wants for us is a smooth running engine so again off to be repaired hope fully with all the advice ive gained from this site and you guys and gals ill have some luck

as bob says blue smoke is oil being burnt

 

as is said before if fuel is not getting into the sump vie the injector pump or lift pump,then it can ONLY be through the cold start,i have seen these devices leak before

 

the vehicle type was often fed from a seperate reservoir of about 5oo mls of fuel.

 

when this coldstart is used in narrowboats it may have the head and volume of 40 or so gallons of fuel ABOVE it,if the spring in the coldstart has weakenedmor even a small piece of grit has got under the valve seat ,it could easily allow 3 LITRES IN 3 HOURS!

 

i have installed electric shutoffs in these systems before.

 

i see your locality is epsom,assume that you mean epsom surrey?

 

i am willing to assist for free,i live in windsor.

 

PM me for more info.

 

thanks for your generous offer we cant believe there are so many helpfull people im sorry that this reply is long in coming but only have internet access at work but hoping things will change soon the guy who did the original build has taken the injector pump and will get a report on that but as far as the lift pump goes i cant get to the boat for 2 weeks so i will have to see ive never even thought of the cold start but have that know in my amunition to fire at him if both pumps still leak i might get him to check it any how as the engine is still under warranty thanks again for kind offer ill place a hope full report on findings as to this problem but thanks again.

the smoke is blue in colour

[perkins 4107]

has the perkins 4.107 got a lucas flamestat fitted,the cold start device which heats and vaporises diesel fuel,which is then drawn into the air intake when starting?

 

if the inlet tube on the flamestat is lower than the level of fuel in the the main diesel tank,it could be siphoning and dribbling through the check valve.

 

the check valve (just a ball and spring)could be weeping when the engine is running.

 

 

what colour is the smoke?

[perkins 4107]
