    Thanks Will for your input, I already have my original IP back on for troubleshooting purposes. If that doesn’t fix it I’ll be putting the new one back on then I can do the bottle test. Is there a volume level I should look for in each bottle? Or just make sure they all have the same...

    Thanks d, I thought Glad meant the oil pressure switch. Is there a procedure in the Stickies on this site to extend the GP run time?

    Thanks Glagulator, I haven’t tried my original IP. I have it installed and all the lines hooked up all I have to do is put the intake back on. No I haven’t disconnected those sensors but I did unhook the 2 wire ECT and the rpm’s went up and still smoked and I think it was still missing hard...

    Hey MrMarty51, I would like to pop my Bosch injectors. I believe you mentioned buying an injection tester to re check your tested injectors. Where did you purchase that tester. Thanks.

    Thanks d, I’m not sure what it smelled like, I’m an old gasser mechanic use to smelling a gasoline flooded exhaust. It wasn’t sweet. I keep checking the oil level to see if it ever rises. I did do a comp. test 400+ on all 8cyl. (post #157). I agree with you on the black smoke being...

    Hi all I just got done getting my original IP in and all the lines hooked up. All the inj. lines where in there right spots. I sure was hoping at least one line was in the wrong place causing my problem. I did run the time set again and the TDCO when back to where it was. I did...

    No I haven’t mess w/ the timing. If I bump up the offset and it doesn’t fall back close to -0.44 would point to the IP I don’t think the chain is bad it’s a new motor. Done its a bad IP. But if it does fall back close to-0.44 could the IP still be bad causing my problem? Hope I find a inj...

    Hi everybody, I don’t want to put anybody on the spot on this forum. But did anybody on here get a chance to look at the engine data video I posted? I do hope the video is viewable. I wanted to know if I set the timing right. Or can you even tell by looking at it? This is my first...

    Thanks dbrannon79, yea I’m not sure it is not the injectors I didn’t check them. Pro Tech Diesel in MT checked them and they were recommended from this forum. I talked w/ the guy and he said he didn’t have to do anything to them they were fine. I believe MrMarty said on here that he...

    Hi all I just reinstalled my injectors after having them checked out they said they were all ok see post #152. Did a compression test because I keep getting cylinder balance codes on all eight cylinders. All 8 cylinders are at 400+ psi. I do need to verify I have my vacuum lines hooked...

    Hi all, I’m still waiting on injectors that were tested by Pro Tech Diesel so I can do a compression test and continue troubleshooting. I wanted to put these 2 videos on here of the time set and TDCO offset I did on my truck because some of the videos of this process were removed in my early...

    Thanks let me get the injectors back in and do a compression test. I’ll get some video of the clear return line. I believe the fuel pressure at the gauge is 6 to 9 psi it’s a liquid filled gauge and it jumps around a lot. The motor does run when I open the fuel t-valve. I believe...

    Hi guys, I just got off the phone with Joe w/Pro Tech Diesel. MrMarty51 recommended them to check out my injectors. He said there was nothing wrong w/them and should not cause the problem w/missing and black smoke on start up. I guess I’ll do a compression check to rule out compression...

    Ok guys bear with me I am on Medicare. The injectors are Bosch not AC Delco. I don’t know where I got the blue and red AC Delco box thing. Some of the injectors had yellow dots on them. Doesn’t that usually mean that they were tested. MrMarty51 you said you had Bosch injectors from...

    Thanks guys I have the injectors out. Now I need to figure out if they are Chinese. I bought them over a year ago I do remember them being in a blue and red AC box. Is there anyway to tell by looking at them? If there I’ll post pictures.
