Finally got it all back together yesterday after fixing a hot no start condition. Replaced the following items:

New Adrenaline HPOP
8 new injectors with all new o-rings
New IPR and ICP
New LPOP
New water pump
New oil rail o-rings

Left the thermostat out to flush the cooling system since I replaced the oil cooler and to put in new coolant. Truck ran like a top without the thermostat in.

Today I finished the flush and fill, and installed the thermostat. As soon as it got hot, it runs like crap. Loping bad and putting out P0269 (Cylinder 3 contribution), P1000, and EGR codes from the delete kit that was installed.

IPR is at about 630 PSI with thermostat vs 827 PSI at idle without. I was getting a code before that the ICP was intermittent, but that has gone away. It's hovering around 30% duty cycle. It starts hot, but it's not happy about it.

Out of time this weekend, but I'm going to pull injector 3 when I have the chance to check the o-rings and look at the oil rail o-rings to make sure they're sealed up. Beyond that, I'm at a loss what to do to fix this thing. I think the Adrenaline is putting out more pressure than the old stock pump which is the only thing keeping it from dying. My guess is I have a high pressure leak still.

 

Has it been driven enough to purge all the air?

 

Mike: was it you that brought up in another thread to not use the Adrenaline seals/orings/gaskets/etc. they provide, due to leaks?

 

That's right.....never occurred to me. I think there were two cases here within the last few months of that.

Here is one thread I can remember. Page three is where the pic of the bad d-ring is

Bass, did you use the supplied o-rings with the pump?

 

Are the injectors you put in from ford?

 

30% is really high. Fix the injector first, that's the rough running issue. Then fix the leak. Did the cover go down hard in the j-tube?

 

I used OEM rings for the pump. Ordered a separate kit because I saw in other threads about the issue with the ones they send you.

Reading in the link above about the o-rings, I saw someone mention oil mist coming out. I definitely have that and saw it yesterday. My dipstick cracked off the top, which is the only reason I noticed it. When I took the oil fill top off I had a bunch coming out the passenger side. Put that back on and it comes out the drivers side. My guess is the passenger side is leaking, possibly on injector 3 since that's having contribution issues?

What should the Adrenaline pump put out at idle in a properly sealed system?

Also, I did drive it without the t-stat quite a bit to flush the system with VC-9, but I don't think it truly got hot enough to cause the leak until I put the t-stat back in. The factory gauge only went 1/3-1/2 of where it normally goes.

 

I don't know that the Adrenaline will actually out out more pressure at idle, it's just a more robust pump. You will probably notice a little more of the gains on the top end when the IPR calls for full on oil.

Healthy idle numbers are typically 21 to 24% IPR and 570 to 640ish ICP....

 

Pressure is controlled through the tune, not the pump. Pump makes the volume. Your pressures should not have increased unless your first pump was physically broken and couldn't produce any.

 

???????

Please elaborate

 

I just replaced my hpop with an adrenaline this past weekend. My ipr and icp numbers were about the same as yours at first. i let it get up to temp and had a run on the highway and romped on it a bit and it finally cleared all the air out of the system. ipr and icp are normal now.

 

I think he's saying that basically the IPR can bypass more volume than the HPOP can output, so any pressure in the system is a by-product of the IPR regulating flow out of the pump. In theory instead of idling at 580psi/22% the PCM could be tuned to jack up the ICP pressure to say 840psi/30% with the IPR regulating back more oil, and if the fuel pulse width modulation was set right it would still run normally-ish?

ICP is mapped to inject a volume of fuel (limited by the injector fuel capacity) over a time interval (FPW) past a physical restriction in the plunger spring. I don't know the technical terms I'm trying to describe, but the reason the engine needs 500psi to start is because that's the oil pressure needed to push the plunger to inject fuel. When the interval that pressure is applied over is held constant, a higher ICP would translate to the plunger being pushed faster, ie further in the same time interval. The interval is controlled by the coils around the spool valve. That's all in the engine programming.

The Adrenaline HPOP moves more volume, which is by itself meaningless in terms of ICP because the IPR is what regulates that volume and "creates" pressure in the system. Maybe JenC is a mechanical engineer, an ME would cry over hearing someone say a pump can create pressure because a pump can only create flow; something else has to restrict that flow to create pressure.

Appreciate the input on that one. It does make sense in those terms, was just a tad confused about the tune controlling the pressure. I am by no means that well versed in the hydraulic arena, it's a whole other realm that many here really don't have much knowledge about.
