Well first off I would like to thank Cajflynn for the wonderful donation of his used RV275 injectors, which happen to show up in todays mail. i'll get some pics up soon... In the mean time I'm going to gather up a few supplies for installing them.

Does anyone know where I can get copper shims and fresh O-rings for these???

Holy Cow!!! :eek: I looked up the numbers on the injector and...

0432193635 / 4183

Comes back as either a RV275 or a 300 HP injector...:confused:

Still much better than stock! :thumbsup:

you can't get good service anymore!

Am i picking up on the suggestion that the RV275 units are about the top out for a stock hx turbo without a potential egt issue? I mean without having to constantly monitor temps if your towing etc? Am I correct to assume that in stock trim there is just not enough fuel to create egt problems. I would guess so since they did not come stock with egt gauge so dodge would be liable if towing was causing unknown dangerous egts an damaging pistons etc.

Well... There in... But... Got the truck running and it runs well but when I got back to the shop and it was idleing it missing randomly. So I started looking for fuel leaks and found that #1 injector line is leak fuel right down the manifold and dripping off the back. But all in all it a good boost of power but the leak is my concern now...:rolleyes2:

That sucks but i guess at least it is not #6... Hope it is just a reset and re-torque.

I think its my fault...(Hate to admit it!) I was using needle nose pilers to pull #1 connector tube and missed the outside and scratched the inside bore face where the high pressure tube seals. :bang: Well lets see if I can correct this problem tomorrow...:red:

Ok thats good.. lets get this thing situated we need some u tube video of some smokey burnouts and serious coal rollin.... :p :stir:

Try to rub it out.A scotch bright pad should do it.Sometimes you can run the engine and open the line and close it again and it will fix the leak.If the tube is bad let me know.I can ask around.

Here is a few pics from the job... Quick easy way to pull injectors using a intake bolt and a claw hammer you can also pry up using a screwdriver which up got to do for 5 & 6. http://forum.mopar1973man.com/picture.php?albumid=3&pictureid=179 Here is my stock injectors after 159K miles and 75K miles of 2 cycle oil. http://forum.mopar1973man.com/picture.php?albumid=3&pictureid=178 The engine area all cleared out. APPS sensor, Air intake, Grid heaters, and injection lines. http://forum.mopar1973man.com/picture.php?albumid=3&pictureid=177

Where the replacement injectors pressure "Pop" tested,check spray pattern and recalibrated prior to install?

No pull from a running vehicle and the O-rings and copper shim replaced... CajFlynn donated the injectors to me... Then another member donated the coppers shims and O-rings (can't remember the name now) As for this morning I went out and fired up the truck and it fired up just fine but still a random miss and #1 tube in leaking fuel... so I'm going to see about polishing the scratch out that I put in the #1 connector tube... If that doesn't work then I'll buy a new tube I guess...

Well I got the connector tube polished up and scratch is gone and so is the leak but the miss is still there... So I'm going to pull these back out and take a downgrade back to stock... Well I got to admit the power is great but the miss sounds nasty like a old Chevy gasser with bad spark plugs... Back to stock here I come...

Ok... So I did so calling around and found a diesel shop in Lewiston, ID that willing to pop test these injectors for a few bucks a piece. But he's swapped right now and won't be available till after the holidays... so I got to put my stock back in for now maybe there is hope...:confused2:

Sooooo.... what your trying to say is No smokey burnouts Utube video upcoming??? :confused::rolleyes:but seriously.. good that you have them Im sure they can be repaired for cheaper then a new set. and no down time waiting for repairs :thumbsup:

I would never ever install used injectors without having them tested and Balanced. Make sure they adjust the pressures as close to one another as possible "Balanced". Call scheids and see where they like to set the pressures at for those injectors andf have the shop set them to that spec.

http://www.southerndieselx.com/ These guys build injectors.They can put new nozzels on and pop test them to be perfect.I had a buddy of these guys cut o.20 off the body of the injector to match up with my 0.20 12v head gasket thats on my 24v.They are one of the best in the usa.They do things to the injector that others will not take the time to do.Call them to get a quote.You will be happy.

dang....that sucks man! is it running alright with the stock injectors? yee haw

Why would Chris take .020 off of the body of an injector when a .020 over marine gasket was used?. Think about that for a minute....You saying that he removed .020 of the injector body and you added .020 of headgasket,thus moving the injector further out of the bowl.I'd be willing to bet money on him NOT doing anything like that at all.They may have removed .020 of the pintle or added .020 lift to them but cut the bodies of the injectors,I hardly think so as it would only defeat your purpose. MoparMan....Do you think the miss is injector related and if so does it ever go away as you run the truck up the rpm band?.Call Chris down at SDX and explain to him whats going on as I know he can take car of you and/or work on your injectors if needed. When you did the install on the injectors did you make sure to use some anti-sieze compound on the o-ring and bodies of the injectors and make sure they were installed correctly?.I know it sounds dumb but I have seen guys NOT get them properly seated or not use any lubricant when they forced them in and have issues due to the O-ring failing....Just a Thought.......Andy

MoparMan....

Do you think the miss is injector related and if so does it ever go away as you run the truck up the rpm band?

The miss only occurs when at idle and warmed. With the engine cold its fine. Take off down the road it got lots of power..

.Call Chris down at SDX and explain to him whats going on as I know he can take car of you and/or work on your injectors if needed.

When you did the install on the injectors did you make sure to use some anti-sieze compound on the o-ring and bodies of the injectors and make sure they were installed correctly?

I basically cheated and dip my finger in the oil of the rockers and moped on the o-ring before installing. So they were lubed up.

I know it sounds dumb but I have seen guys NOT get them properly seated or not use any lubricant when they forced them in and have issues due to the O-ring failing....Just a Thought.......Andy

Well like I said I found a local place here in Idaho that will to pop test them for cheap. As a matter of fact I can round it into a shopping trip and make it worth while. As for parts I might have to talk to him about that.

Well I got to admit I'm green to doing injectors... I read tons of article but this is my first...

Ok... back to stock and miss is GONE! I double checked everything and I got it done in nearly half the time as I did the first time... But I took the truck out and got it nice and warm and brought in back and it just purrs like it use to... Now I'm going to contact Idaho Diesel Tech after Christmas and see about getting these RV275 popped test and fixed up...

Weston built mine.Chris helped me get in touch with him.If you lift the head 0.20 the factory style injector is out 0.20.Whats so hard to understand.Then if you cut 0.20 off the body of the injector it sits in the factory location.My injector guy is a pro.He doesent get them from a vendor he builds them him self.When i hooked up with him he asked many questions.I bet when you or others get injectors they just ask the year and make.Mine asked what lift my cam has,turbo,auto or stick,what kind of gears i run,tire size, and he also wanted to know not only if i spray nitrous he wanted to know what jet i use.He wanted to know what kind of a port&polish job was done on my head and if the intake was cut off etc.I have had off the shelf injectors.I have no problem with people who want to run them.There is some good ones out there.The reason i responded to this thread was to help.Southern diesel x is a good place to get injector help.
