Now my knowledge of diesels is limited but this confuses me...
I have 2 x 550 HP Detroit Diesels one of which is down on power substantially and smoke when above tickover, even with no load. I've had injectors and turbos replaced but now the engineers seem confused (it would help if they spoke any English or me Spanish!). So what are possible causes? My logic goes like this:
Smoke is balck and sooty so it can't be from oil (that would be blue).
Black smoke suggests that the engine is running too rich and that must mean something needs adjusting.
As far as I can work out the engineers think that there is a fuel blockage but surely this would mean it running lean?
Any thoughts on possible causes?
Thanks
