2007 Supercrew 2wd 5.4
Bought the truck with a locked up engine. Got it home and pulled the oil pan, found one of the rod bearings spun (BAD). After seeing the sludge in the rest of the engine, I decided not use that motor at all. Went to pic a part and pulled a motor that looked like it had been reman'd. Pulled driver valve cover eveything looked nice and clean, made the mistake of not pulling pass side (and that's why the truck was in there in the first place.) Cam caps had come loose and destroyed the head. So I ended up using the good head from the new motor and the pass head from the locked up motor.
heads went to the machine shop and I was told they were ok, with the exception of one bent valve (which was changed). Rebuilt engine, crank and rod bearings new M340HV oil pump, Aftermarket timing set (I know see the comments below). New aftermarket cams and rocker arms and lifters. Motor was cleaned, no sludge. Fresh 5w30 and motorcraft filter installed.
Truck ran great until warmed up and then had P0022 code, went online and found out how bad the aftermarket timing components are. Since I now have Ford phasers and VVT solenoids.
I'm now getting codes P0022,P0300,P0305,P0307 and running like crap, if I tap the throttle it clears up and sounds great again. Until I put it in gear and the idle drops.
Checked oil pressure and I have 25 cold and 11-13 hot. I have read a lot about the tensioner gaskets being blown out and then I found this https://www.google.com/search?q=ford...bAC6TP3XY,st:0 at 9:39 they talk about the tensioners and say it's a myth.
How do I check the cams for excessive leakage? should I pull the front cover and replace the tensioners?
I know I'm missing something in the rebuild list or troubleshooting I've done.
I really appreciate any help.
Forgot to add, if I disconnect the VVT truck runs fine, except for the expected low power and bad gas mileage.

Your link leads back here. That aside, the plastic seals do blow out. These aren’t your pop’s steel 2V tensioners. That definitely could be why that one bank isn’t staying tight.
Could be cams, could very well be trashed thrust washers in the crank. Running 11-13 PSI for a long time will do that. Ol’ baw Fordtechmakuloco has a video on YT about checking for end play and whatnot.

First let me say I do not own a 3 valve engine and we need others to chime in.
You probably know this but P0300, P0305 and P0307 are related to multiple misfires related to cylinders 5 and 7 and while these are on Bank 2 and I would guess there is a chance they are related to a cam timing issue but then again maybe not. Did your injector and COP connectors snap together properly? If not I would revisit those and if necessary remove the red rubber gasket and see if they snap together properly. Did the COP springs seat properly? Once I had a spring fall out of place during a spark plug change and it caused a miss.
Oil pressure of 11-13 psi seems low. Did your new oil pump come with a new oil pickup tube/screen? If it did not then we need to make sure the old pickup screen is clean. Debris can sit in the pickup housing and get sucked up against the screen as the engine runs and RPMs are increased.
As for the P0022 I have attached a couple of pages from my Ford’s Car/ Truck “Powertrain Control/Emissions Diagnosis Manual” for Model Year 2007. Sections are highlighted with an arrow and they may be out of order.
Thank you for the info, I have not checked PCM connectors.
The solenoids are new Ford.
When I changed the VVT solenoid last, I moved coils around to make sure I still had a 5 7 misfire and the codes did not move with the coils. I think I forgot to put that in there, before I put the Ford solenoid in I did have 300,305,307 codes which I assumed were due to the 0022 code.
Also the oil pan was changed and the pick up cleaned thoroughly.

Well it's definitely an oil pressure problem. I added Lucas just to see what would happen and did not have any issues. Oil pressure hot was right at about 15-16.
So how do I find my issue? Is there anyway to check Cam clearance, I never found a spec for it. Or should I just pull the front cover and replace the aftermarket tensioners?

The hot pressure is way too low according to the below Google AI query.

Still way too low according to below query.
.
Google AI: For a 2007 Ford F150 with the 5.4L engine, the normal oil pressure at 2000 RPM and warm engine conditions should be between 40-60 PSI,
. At idle (warm), the pressure should be at least 15 PSI.
Detailed Explanation:
Normal Operating Pressure:
The 5.4L 3V engine in your F150 should ideally maintain an oil pressure between 40-60 PSI when the engine is at 2000 RPM and warmed up, according to automotive forums.
Minimum Pressure at Idle:
When the engine is idling and warmed up, the oil pressure should be at least 15 PSI, according to a service manual.
It sounds like the oil pressure gauge is giving false readings.
In any event, given the results of using Lucas I would try using a thicker oil. I've read posts here where that has been helpful.
