I was getting my turbo all situated and pulled the dipstick while I was under the hood and my truck is making oil. It has been almost a year since my last injector change but I did not use new orings so now it looks like I get to do it again.

So I need a part number for new orings. The dealer is closed now, but come monday, I'll call them and if they are too much, I'll drive 30 min to cummins.

Anyone have a part number handy?

 

I don't have a part number but went to the dealer for inj. crossover tube o-rings and they said $3 each. I laughed, went to Cummins and bought 6 for 5 bux!!!!

 

There is no o-rings on injectors, there are o-rings only tubes.
The ring you see around the injector is actually a metal spring.

 

The injectors have RUBBER O-RINGS. If you have little springs on yours something not right. O-Rings for sure. Thanks Steve B.

 

Whoops....you're right, I just checked. Sorry BigBlue, too much...."barley pop" tonight !!!!!!!

 

Having one of those night, Valv.. It's an injector fire ring?

 

O- Springs Its still pretty early, don't drink to many more. Thanks Steve B.

 

Alright guys, it looks like you're doing more drinking than typing or researching. I have never bought anything from cummins. People scared me away so far cause I don't even know what a CPL# is. Where it's located on my truck etc.

So if anyone has a part number, I might just go straight to cummins.

 

I think the CPL is your engine# that you need to give to cummins. Its a metal tag located on the timing gear cover right in front of the VP44.

 

you don't even need the CPL# you just need the engine serial #..........and they'll give you any part you need. Engine serial # is on the same tag anyways though. I go to Cummins regularly and I've yet to be asked for the cpl.

 

Ok, I'll do that come Monday. Then I have a few hours on Tuesday to figure out which one, or ones are leaking.

 

I'm still enjoying my "pop" !!!!

Funny part I just installed mine 3 weeks ago and I remember I oiled them before installing so they won't be dry....

 

If you're going to do 1......do them all. might be the jumper tube leaking at the injector too.

 

I think if a cross over tube was leaking, it would run out of the motor, not into the internals. My cross over tubes have never been out, I only pry them back 1/2" and the oring on them has never been out of the bore.

I'm sure when I pull the valve cover there is going to be an obvious bubbling around the bad oring. What is weird to me is that I watch my oil like a hawk and this problem just showed it's face in the last 3000 miles. I haven't been running anything different as far as additives, just a little two stroke oil from Walmart. I should do all six but that 5th and 6th injector are a pain in the butt to get tightened.

 

cpl = controled parts list, but you should be good with the engine serial #. they are both on the tag that should be on the right side of the engine under the apps sensor.
