I'm sure several of you will recognize my username by now, and I'm still having issues. I had a HPOP leak, fixed it with a new STC fitting, re-sealed the injectors and HPOP. I had an electrical issue that is fixed, and not relevant to this. Then I had hydrolock and installed a new injector and re-sealed 2 more. It's a 2005 F350 6.0 stock everything.

I've had an ongoing high oil pressure problem since I fixed the first HPOP leak. It's high at startup, and now it's even higher. I'll post pics of my Torque percentages. It's around 1300 psi at starup, there's a definite knock on the driver side now, and it's smoking pretty good. I'm going to do an air test, but it runs just fine. When I give it gas, the knock goes away and it seems to stop smoking. So apparently it's just an idle situation. I actually drove it about 85 miles to get it home with it doing this every time I stopped. I just do not get why my HPOP would be so high at startup. I haven't had a chance to see if it drops while driving, but I assume it does with how well it did on the way home. These values were taken 20 mind ago, it's around 55 degrees here, cold start. Thanks for any and all ideas!

 

I just noticed that my FICM main power and FICM vehicle power are about the same. I have a new phone and had to configure this Torque app quickly to check it. Surely I used the wrong PID for one of them. My FICM has been functioning fine at 48-49 volts, and 11.5 on both sides.

 

Icp voltage jumps out at me...needs to be 0.82v or higher from what I've read

 

The ICP Voltage is odd to me too, because it was .2 the whole time I was watching it. This is the first I've seen it not be .2 or a little above. I'm gonna try unplugging it.

 

I was going to ask if it was unplugged.

 

Unless that is a screenshot of the glow plugs cycling, your volts are severely lacking.
Refresh our memory again please, did it have this knock before the hydrolock? #6 was the bad one correct?

 

A bunch of stuff doesn't look right. Voltage as Mike pointed out. MAP should be higher than BARO, it's probably plugged up, should be closer to EBP when running. FMP/FVP are fine, even the logic is fine at 11.5. It's low because main voltage is low.

 

Here's a cold start on mine. Rotella 15w40, maybe 300 miles on the oil.

 

Vacuum @.30, that's funny.

 

I don't even have FICM sync on mine. Is that a custom PID?

Anyways. I started it again and got these numbers.



The knock was not present before I did the number 4 injector. I resealed #2 and #4 because I pulled them out to have a reference on condition for number 4. There's still a LOT of smoke from the exhaust, and I see what looks like a little bit of moisture around the Y-pipe where it connects to the turbo (I'm not sure if that's actually called the up pipe or what). No leaks under the truck, and like I said, other than the small knock (maybe like tapping your keys on the hood) the truck runs fine other than the smoke. This truck has more personality than I've ever seen. I'm beginning to suspect the FICM. Can it cause massive amounts of smoke if it's bad?

 

 

And you used a new copper crush washer on each injector? Smoke sweet smelling or fuel?

You map sensor is plugged. Pull the tube and clean it and the nipple it's mounted to on the intake.

 

Bingo! good eyes

MAP and BARO should only be the same at Key On Motor Not Running.

 

In the very first photo link, your screen shows ICPv to be 0 and the psig to be 1357.7 psig. IMO the 1357.7 is a default value because of no/bad sensor input (might have been unplugged as Randy suggested?).

 

Yes I used all new seals and copper washers on the injectors I removed. I will definitely clean the MAP hose. I never thought about that.

The ICP sensor wasn't unplugged during any of these pics. When I unplug my ICP sensor, it says "no data" for all the related values. The truck also runs and acts exactly the same whether the ICP is plugged in or not. Same thick white/grey smoke, same ticking/knock. I say ticking/knock because it's definitely not super loud, but you hear it easily. Reminds me of a valve ticking on a gas engine, but maybe a little louder. It's got me stumped. I mean, I drove it like this 80+ miles home. It definitely didn't like sitting at red lights, but it made it. If I thought I would have done damage, I wouldn't have drove it, but like I said, I give her just a little gas and it smooths out, smoke fades, and off you go. I had plenty of power on the interstate even though I stayed around 55 the whole way and wouldn't even let it downshift up hills. It starts right up every time. I just don't understand the level of smoke I'm getting. I've quadruple checked every CAC tube, the turbo fittings, intake, everything.
