Injector service

[madhatter1]

RPM in Lauderdale is highly recommended but my local mechanic normally sends his stuff to Pinellas Diesel. 8-92's and need to replace all tips plus maybe more. My mechanic will send them to whoever I want. Anyone have experience with Pinellas Diesel?

I would prefer to have my mechanic work with a shop he is familiar with and comfortable with. But don't want to do this if it really matters a lot and RPM is the place that should be used.

Thanks for any info.

May I inject a thought, ensure your injectors are rebuilt (Not just replaced) and popped at the shop to ensure even performance in them all.

I do lean to use your tech's shop. If any issue, he may have some more clout there than a cold customer.
Now, If your tech's shop don't pop & match them (ultimate testing), Then I would find another shop that does.

Watch out for that Derek Avenger guy. Everything I send to him comes back right.

Old & dirty air filters would be the first & cheap Items to check. Incomplete fuel burn usually leaves the soot trails.
Throttle delays removed (like on our boat) or out of adjustment can still soot up a transom.
Slow turbo(s) or bad injector tips are culprits also but further down the list.

Thanks all for input. History. Boat was bought from Capt. Dave Disesia. A true DD mechanic. But time takes it's toll and we did have to service some turbo issues and shim governor on port side to get full loaded RPM's. As posted on boatdiesdel.com there is zero visible exhaust trail behind the boat. but there certainly is a station wagon effect since we have to rinse salt spray off when done running. So maybe normal, I don't know. But original question on boatdiesel was about underpropping a bit since top speed I have now is not needed and a reduced top speed is acceptable. Original question was about reducing load on engines a bit to also get better airflow (cooling) running same or maybe slightly higher RPM's. Agreed that I don't think I really have an issue with injectors right now but prefer proactive maintenance. Rather spend $ on maintenance than repairs and down time. And also want many, many hours out of the engines without rebuild. Although I could if needed.

I agree with Robert. Derek does great work. You'll get the attention to detail that you would expect.

You guys are the best, Thank you.

Why do we suddenly feel the need to replace "all the tips?" At least your port engine has a fairly fresh set of matched injectors in it. Did you run some junk through them or something?

Avenger, if you go to boatdiesel Detroit forum you can read my original post and conversation with Mr. Sparks. It will fill you in to the whole conversation. What is the name of your company and where are you located?
