I have just got my Diecon Marinised Kubota engine serviced with a reputable marine engineering workshop and they informed me that the injectors were down in pressure and incorrect spray pattern. The engine only has 80hrs on it and I was wondering from the helpful forum members if they can shed light on the period of time between injector servicing. I am aware that the Diecon engines are re-birthed from a Japanese tractor. I bought the yacht 5 years ago and the engine was new when I bought it.

Injectors can do hundreds to thousands of hours, they can sometimes out last the engine. If the motor starts easy and doesn't blow white smoke I wouldn't worry.
Water in fuel is a big killer of injector nozzles. With only 80hrs,, to start testing injectors the mechanics must have found the motor producing some symptoms of poor fueling, It would be extremely rare to remove injectors after 80 hrs of service. The only injectors that I have ever adjusted during regular servicing are GM/ Detroit.

Not a comment on injectors, but it looks like you have used plumbers tape around the heat exchanger anode, which will insulate it from doing it's job.

Thread will slice through the tape to make good contact as it tightens.

Never heard of a Kubota having an injector problem. I'm with jolene, they should outlast the engine.

Agree with previous post
injectors last years but contaminate fuel will give issues 80hrs is not much ,
has the engine change noise .?
A general service I'm surprised that this kind of inspection was carried out too???!!

Have used a ChemTech diesel additive on a 2.8L 4WD engine at extra strength when the motor was running rough, cleared the problem within half a tank…presumably cleaned dirty injectors. This stuff was recommended by a mate who worked for his uncle who owned a diesel servicing business specialising in Mercedes Benz trucks, and most of his customers used it. I definitely agree with previous posters that injectors should not have had trouble with that little time on them…in the normal course of things.

On Ramona's advice I started using this product. Seems good. They have a whole lot of additive products.
