alright fellas so Im working on my little project, its got 370hp marine injectors. One of them is either plugged up or dead, When I undo everything and try to get the injector out I cant get it.

I was told that I could thread a nut onto the injector and pry it out.

anyone got any little secrets to help me get it out?

The nut they are talking about is a lug not, not the one from duallys but the one off of the front should fit, thread it on and use pry bar under it, saves the threads and with a little elbow grease it will come out. Most (but not all) on this forum believe that the 370 Marine inj is not good for an automotive application. It has the wrong spray pattern and will probably result in washing down the cylinder walls and lead to fuel in oil and damage to cylinder walls. I am one of the ones that believe you should not use them for daily driving, but it is your project, and you need to weigh the pros and cons and make your own decision.

I havent found anything about people saying they damaged the motors, but everyone says its the wrong spray pattern. Its kind of strange that city diesel would sell them....interesting

I have never heard of anyone damaging there motor but the problem I have heard with the 370s marine injectors is that they don't have the correct spray pattern :CRY::CRY::CRY::CRY:

Unless they were rebuilt or manufactured by someone that did give it the correct spray pattern :thumbsup:thumbsup:thumbsup:woot::woot:

They are a business, what do you expect?

Years ago 370s used to be some of the biggest injectors available for the 12vs before the aftermarket grew into what it is today

it's never made sense to me "washing" the walls of a diesel. i understand it damaging a gas motor because gas provides no lubrication. in a 12 valve, correct me if i'm wrong, the pump is lubricated by the diesel it's self, hence all the stink about additives to lube the pump better due to the new no.2 fuel. so as for "washing" or "sticking" a piston, i don't see how the wrong spray pattern would do this. i do see how the wrong spray pattern could be detrimental to fuel milage and performance because it's not spraying into the bowl, but not "washing" down the walls. someone please tell me if i'm thinking illogically right now.

I wonder what the difference in mileage and perfomance is with the marines and with another type of injector with the same rating.

Also a slide hammer works great, in case any one wondered.
