nuber 5 injector leak???
I bought a set of used 370 injectors for my truck and all but one of them went in and do not leak, and the first time it was spraying abit. I have done some searching and many people say it is probably the copper ring not sealing correctly. So I pulled it out again, there was some "gunk" on the bottom of it so I put it back in, tightened it back down, pulled it out again and it was clean. So I put everything back together took it out again, it didn't spray but it was bubbling right at the bottom. Anyone have this happen to them or hear of this happening?

Try a new copper crush washer. Also, make sure there is no grit in there.
Cummins part. |
Grit as in? just gunk stuck into the threads of the top bolt on the injector?

i need to get new crush washers myself..i have minor bubbling from injector 4,5,6 ...im getting it tommorow from cummins in the buffalo area...anyone know the part number to save me time describing it to them?...my biggest concern is restarting the truck on my own

I use a shotgun bore cleaning kit the swab gets everything out thats in the injector hole. You can order a injector install kit it will come with new crush washers, put a buger of grease on the injector to hold the washer while putting injector back in.

i just came back from cummins and got the crush washers..all 6 washers for 20$...the gray re-usable valve cover gaskets cost me 25$ for all 6 while i was there
