Injector Knock
What does it sound like? I have checked my valves and among other things and still at 1800 to 2300 rpms with no real pull I have a knock rattle like metal tapping. I don't want to drop a pile of money changing parts if I can narrow it down. Any help please!:s:

How does it run when you first start it in the morning?? Mileage ok, no fuel in the oil??
|
no fuel in oil, seems to run fine when I first start. When at low idle it purrs like a kittin when cold and kicks to high idle has a blurp in it but nothing serious. I figured that was just from the 3 cylinder high idle I heard about. No excessive smoke. Just when you get to 1800 it kinda metallic knock. Only when not under load. Going crazy here. Worried something is wrong but don't know what it is and I don't want to just start throwing parts at it. I have never heard a injector knock or rattle so I really have nothing to go off of. Thanks for any help.

Can you turn your high idle off:humm:
|
no, don't think so, if so I don't know how
|
Do you think I should recheck the valves, It really sounds like valve rattle:humm:
|
mine is doing the exact same thing. idk what the hell it is but i say not injectors cuz my injectors are only 2 weeks old and it sounds like we are havin the same issues with the knocking
|
Thank god someone is with me, it is crazy and driving me nuts. It has my stomach in knots just thinking about it. Gonna pull the valve cover again this weekend, try it cold and try it hot. Anyone know if cold lash is different than hot lash.
|
id say run some fuel additive and hope like hell that that will fix it. but you also gotta remeber that cummins have a weird "knock" to them anyways so it might just be the way the cards fall

I'm running into the same issue with my truck, but I'm running stacked programmers and it only does it when Its cold..so wtf??:argh:
