This is when it takes 140F + coolant temp to stop the smoke.

The next problem on many trawlers is a constant under load , which carbons the rings , sometimes to sticking .

Add in the oil dilution from the fuel passing the rings,at low load , and SURPRISE ! a smoker.
Dead on!

You might want to talk to TAD.... Last time I talked to them, it would have been easier to send them my old injectors as cores, and they would send me back injectors that had already been rebuilt and tested.... Just can't remember the price! But it was so close to the rebuild price that unless you were emotionally attached to your injectors there was no reason not to.

tad ?

note: I don't know why but this forum keeps changing the upper case "TAD" to lower case. But who or what is "TAD"?

note 2 OK, this time it didn't. Same question.

They do more than just Perkins.... They do Volvo Penta, Cummins, and others as well. They do however do handle a lot of Perkins items.

My injectors are Bosch. They have a plant just around the corner from me but I doubt that helps.

I recall reading a warning about them sticking or breaking or something like that when trying to remove them. I haven't really tried, but I suspect it's time to have them checked, The PO didn't give me the service records for some unknown reason.

They had said around $100 per injector and they billed out over $200 each. A new injector from Yanmar was $175. It took a bit of discussion to get the bill down. They even had the guts to say that the ones I had were now new.

So just make sure you can't buy new for close to what they want to rebuild them.
Sounds like they did not have the expertise to rebuild Yanmar injectors and were use to Truck Deisels.

If only that were true. But they do have the expertise and they are the largest boat diesel mobile repair shop in New Bern NC. The major truck diesel repair shop is less that a couple of miles away.

Just tried to be rip off artists. So I help them out when ever I can.

I have a Perkins 6.354 Diesel and I have just had 6 injectors rebuilt as well as the CAV injector pump. The pump was completely shagged, all of the internals etc needed replacing (everything but the outer case was replaced) and the injectors were like water pistols and not atomising the diesel. Total cost was $1,823.50.

I've never run the motor so I am rebuilding it. I dropped the injectors and pump off to be serviced. It wasn't till I got a call that the extent of the repairs needed was evident. I went down and they showed me the stripped internals. Cam, fins etc
