Fuel Injector problem

[runner911]

I currently run a Merry Fisher 655 which I use as fishing boat .

It is fitted with a Volvo Penta D3 110 engine which has run a total of just under 700 hours.

Lately I have noticed fumes coming into the cabin when the boat is under way.

Inspection reveals that number 2 fuel injector is " puffing " slightly. when the engine is running . There is no neat diesel coming out, just fumes . In addition there is what appears to be a sort of resin around the bottom of the injector together with a sooty deposit.

Anyone had this before ?

Could it be that the insert into which the injector fits is leaking fumes after the explosion has taken place in the combustion chamber ?

Advice anyone please ?

Hi

Can you locate where the "puff spray" comes from. Nozzle and fuel pipe (8), nozzle itself(1), or nozzle attached to motor fitting (5-7)?

Nro is part nro look link nozzle picture.

Have you tried nipping down (gently tightening ) the clamp bolt or you may have to remove the injector and clean the area before refitting check what the WS manual says about removing injectors and pipes first

Isn't the D3 an XC90 motor and therefore injectors are very cheap?

Hi,

Same ears with a new one if you can not fix it simply by tightening the nut. The common rail nozzle does not make sense to open itself because micron class particles that you can hardly see can cause problems with the l.
