It's my turn for the P1211 poke in the eye?

[MeTo]

I have about 6000 miles on my Swamp's baby injectors and tunes. At about 2000, I started getting P1211 codes. I took the chip off and that helped getting the trick and camper home from Arizona.

Can anyone say for sure a 97 15 degree stock HPOP with 76,000 miles on it, supply enough oil volume and pressure for the Swamp's baby injectors? I never got a CEL before the injectors were installed.

I would like to say the baby injectors are great; for me.The Swamp's tunes are much better than the TS6 generic tunes. At some point, I would like to try Bill's tunes.

The injectors and compression check was done by Performance Diesel in Green Bay. Fuel pressure is good and I'm getting 17 psi of boost. I changed oil (Rotella 15w40) before I left and is full. I cleaned meticulously and installed the fancy (can't remember the name) o-rings in the IPR before I left. I also checked each part with a magnifying glass for scoring or any indication of possible leaking or binding.

Today I will deadhead the pump to check pressure and then the left and right banks for pressure and leak down. I will post the pressure test results tonight.

The problem only occurs under load. So I don't know how to visually check each injector for the amount of oil coming out, unless the truck would be on a dyno?

Are their any electrical tests I should be considering or is this a mechanical issue?

So, would anyone have some advice before I start throwing money at this? I.e. 1st IPR, 2nd Adrenaline HPOP and last new injector o-rings.

Check your pulse width under the high load you are experiencing the problem.

I believe you need a bigger HPOP.

I deadheaded the HPOP and got ~3400 psi, passenger bank is ~3400 psi and the driver's side bank is ~2500 psi. I pulled the valve cover, removed the four injector spouts and disconnected the two electrical connectors. I had someone turn it over with the starter. I got about a teaspoon of oil about every 3 seconds oozing out of all four injectors. I called Jon at Swamps and sent all four in.

I'm no expert on diesels, but a non-injecting injector should not be leaking oil. All four? Remand injectors; my bad.

Good job on the troubleshooting the leaking poppets. I would have sent in all 8 to feel better about being balanced, but you should get some pressure back.

I agree, I'm hoping I will not regret that? I'm going to pull the passenger valve cover and check them. I guess I will see how good Swamp's customer service is first hand.

Tomorrow, I'm going to contact some injector professionals and bone up on injector knowledge. After the fact knowledge is always more expensive.

I switched the remand swamp babies out for NEW Alliant ACs, no more problems. The difference is night and day. I will never buy remanded injectors again; the lesson has been learned.

You could've damaged an Oring in the first set.. And the second set you didn't.
