I gotcha. Yeah that bus is pretty weird having a c6 and an idi in 1995. I tried advancing the timing and it didn’t really do much to improve it, maybe a small amount. Retarding the timing made it seem worse. I only advanced it about a 1/16 of an inch. It does it more while its cold and then when...
Thats nice. I figured the pump and injectors would be alright. I got a stanadyne pump which ive heard things about them but figured itd be an alright pump. Ill have to check on the timing and make sure its spot on. That sucks on the pump i paid like 700 for it or something like that. And...
Timing has been set by lining up the 2 marks then by the timing light. It has ran fine for 18k miles. Just started doing this on me. I got injectors from advance auto because I thought that was the issue. They are brand new bwd
1994 7.3 idi with a turbo will idle all day long and starts up like its a brand new truck. When it gets past 1000 rpms it starts stumbling and will blow like a faint blueish type smoke. Its not a really thick white smoke like injectors. This truck has brand new glow plugs, injector pump and the...
Alright i replaaced all my injectors and it is still making the same noise. Its only really bad when i get up to temperature. Its more of like a suction cup kind of noise and im kind of curious if i might have a head gasket thats bad and allowing air to travel between the head and block. Im not...
Alright im kind of at a loss, im still not sure as to what the noise is. Sometimes it will go away and then it will come back. Sometimes it sounds really bad and sometimes its quite. I took the valve covers off and everything looked ok. Oil is being pumped up fine and all. I switched the...
Would it just be like a black soot kind of on the bottom of the valve covers? This would tell me if i have bad valve guides or exhaust valves? Ill probably check this out too while im jacking with the injector
Im hoping it is just a fuel knock too. Thats kind of a bumber about your exhaust valves sticking open. The diesel deep clean and atf fluid didn't work to clean it so sometime when i get time ill swap in some newer good injectors and see if that fixes my problem
Thanks for the input and i hope your right that its fuel knock! I threw some diesel deep clean and atf in to see if maybe i could clean out the bad injector but if worse comes to worse ill get new injectors
I havent found out what the problem is yet. Im not sure how old the injectors are but im hoping its not a stuck lifter. I guess i could pop the valve covers off and look to make sure everything is good. I might try some new injectors, but i think first ill dump some atf and diesel deep clean in...
