  1. Stainless E9 injection lines, failing

    Well finally got the last two lines bent, polished and mounted, guess what now I have two lines leaking past the threads at the head! One on each side of the engine, I can't win. Does anyone else make oversized lines? I doubt they could be welded up, there is not much room for a weld in there the way that they make them
  2. E9 oil pump pressure relief spring

    The reason that made me think my friend was having a spring issue was also that when we got all our engine parts from Dale Francis to do the top end of our engine he also highly recommend putting a spring in, my oil pressure was fine really about where it is now, it may be a bit higher now but the spring was worn. The old spring is the one in the back and the new one is in the front, sure looks like a difference to me. Those shiny spots on the old spring are spots where the coil it worn thin. So before I was going to tell my friend to pull his pan and check the spring I figured I'd see what you guys had to say about it.
  3. Stainless E9 injection lines, failing

    I talked to Columbus diesel, Dan Magers and he says the factory torque spec is fine and can not explain why this is happening. I'm waiting my the last two lines and they will all be brand new, he also said that I may have to put an extra mounting clamp up by the pump where they are breaking, anyone done that? Anyone have pictures of how they routed there's? Thanks all!
  4. Hey all asking for a friend, just wondering if a broken oil pump pressure relief spring would cause low oil pressure, seems like it would. the truck in question is around 40 lbs at governed rpm and about 30 at idle. Book spec says that's low at governed rpm. My truck as around 80-90 at governed rpm and about 40 at idle, but I have a brand new oil pump pressure relief spring in it. Any thoughts? An yes I put a mechanical gauge on it to check. thanks all

    Well Columbus diesel is standing behind there product once again, there going to make me up 2 more lines. So I guess we will see how these ones go back in black, where do you adjust the needle lift your talking about? Is that within the injector?
  6. Stainless E9 injection lines, failing

    Francis Engineering "built" my injectors, I know on the outside there a Bosch body. I also know that when I was having the "tick" sound in the #8 injector I pulled and sent the injector to Columbus diesel because I did not get any response from Francis Eng., I then sent the injector to Dan Magers at Columbus diesel and he said they had not seen valve tips like the ones I had. And was not able to repair it due to the fact he would have to try to source the part. I remember Dale telling me when I was ordering them that they were something like a Bosch body and ambac internals
  7. Stainless E9 injection lines, failing

    Unfortunately I don't, I wish I did I think there is a lot more to work with, for instance my gross weight is 130 with a big machine on the lowbed and the highest I can get the pyrometers is 800-900° as far as the fuel lines go iv had 2 fail and replaced them, Columbus diesel and myself talked it out and determined that it may have been bad flares so he replaced the other 6.( I just had to send him the tube nuts off the old lines) I get them back, bend them up just like factory sand them and them polish. I re installed the new 6. I fire the truck and now the first one I replaced months ago is leaking at the injection pump like shooting out like a sprinkler. This is exactly what they all have done they seem to crack right at the flare at the injection pump. I don't know what else I can do, the fit an thread in perfectly, I don't have to force anything. Any thoughts I'm running out of ideas and sanity Thanks all

    Back In Black Pulling: the factory spec is: nut at injection pump: 25ft lbs Clamp screw at cyl head: 35ft lbs nut on clamp screw: 15ft lbs are these the specs you follow? Or close to? These are the specs iv been torquing them to.
  9. Hey all, other than the compressor being worn out, what else would cause oil to come out the air intake on the compressor. It's coming out bad enough that it is oil soaking the air filter to the point it's collapsing. thanks for your help!
  10. Stainless E9 injection lines, failing

    Back In Black Pulling, I have the same lines as you and I keep having a problem with the lines splitting right at the flair at the injection pump. Francis engineering tweaked my ambac pump and I have injectors done by them as well. I bent my lines the same as the OE Mack and ran them in the factory holders/clamps. Perhaps I'm just having just poor luck, have you removed your lines and re installed them at all? I cracked the third line in less than a year (less than 4K miles) on my way home from Gerharts P.S. That was one heck of a launch at Gerharts this past weekend! Your truck is very impressive!
  11. Hey all another E9 question that has me puzzled, is anyone using oversized stainless steel injection lines on their E9? If so what injection pump do you have, and have you ever had an issue with them? I'm curious thanks all!
  12. E9 head gasket failure after 2500 miles?

    Well I was finally able to get back on this problem and I can finally confirm the tick noise is the #8 injector. I moved the injector to #4 (opposite side of motor) and sure enough the noise traveled with it. So I pulled the injector and got ahold of Columbus Diesel and they said they would take a look at it, sent it to them they pop checked,tested, and cleaned it. They said nothing was wrong it functions normal, but they did say the spray pattern did seem a little odd. They didn't have another one of my injectors to compare to so they sent it back to me. Re installed and sure enough it still ticks and still misses and shakes the whole truck under very heavy load. All I know is if I watch my burn mirror every time it seems to fire odd a much darker puff of smoke comes out of the stack. I'm lost here other than buying another injector is there anything else to check? Any other thoughts? Thanks all!
  13. E9 head gasket failure after 2500 miles?

    So I'm thinking because I cracked that injector and the tick stopped. There is obviously still compression, an if it was a fire ring problem wouldn't it still make the tick noise? So does that mean it's an injector pump or injector failure/ problem? Just trying to figure out what is the next step in diagnosis
  14. E9 head gasket failure after 2500 miles?

    Well the truck has been parked and have been busy doing other work, today I had a quick moment and I cracked the #8 injector at the injection pump and it killed that cyl and the ticking noise stopped, closed the line and it was back, so I tried #7 the cyl died when I cracked it but the tick was still there so I think the issue is without a doubt something wrong with #8
  15. E9 head gasket failure after 2500 miles?

    Is there a way to test the injectors without a machine to do it? Other than cracking the line at the pump,and trying to blow air through to see if it's stuck open? I'd like to pull the injectors out of that head and check them. And I'll get new injector install o rings and a nozzle seals for when I re install them, because I'm sure those will not be re-useable
