2011 FX4 with 155k miles. Had hesitation/ shuddering when getting on the freeway with no flashing or steady CEL. Removed 5* 91 perf tune and continued to monitor. Next day same issue but this time P0303 Misfire Cyl 3. Plugs were fresh and properly gapped so i switched plugs between cylinders 2 and 3 and cleared the code. Still ran poorly, threw code again, still cyl 3. I then swapped coils between cylinders 2 and 3 and cleared codes again, then drove home for lunch and returned to work. No codes thrown but was pretty much constantly stuttering anytime there was any amount of boost. Parked it after lunch and then after work there was a ticking/ tapping sound on startup, still no codes thrown. Sound seems to come from pass. side top end/ under intake manifold. Minor tapping felt through pass. valve cover near cam position sensors, intake manifold as a whole, and most pronounced in the high-press fuel lines and pump(cavitating/ pulsing feeling). Dealer said drop it off and they would diagnose exactly whats wrong with it. They cut open the oil filter and found metal in the paper element, determined I need a new engine and digging further into the issue wasn't worth the time or effort. Brought it home, pulled valve covers and found no visible damage, sound got slightly louder when started without passenger valve cover. Now I'm trying to figure out all the options available and overall costs. I'm stuck between being practical and wanting the pipe dream. Dealer quoted $5k for a reman long block, $850 each for new turbos, and about $3000 for labor. I'd like to do the work myself and put that money towards upgrades. Here's how I see my options and some other questions I have. Please let me know if you have suggestions or any other questions. I have videos of noises if it helps anything.
1. Ford long block, reuse turbos? Any metal thats possibly stuck could be flushed somehow before swapping?
2. Ford long block, new OEM turbos(48/51?)?
3. Ford long block, rebuild turbos w/ Batmo wheels?
4. rBrown mild long block w/ timing upgrades? (Chains, Tensioners, Guides,... phasers?)
Is a gen2 motor swappable into my truck? I assume I'm lacking the needed electronics for injection etc.
If I'm changing turbos can I change to the 51's? Change from mech. to e-BOV setup? What are the pros/ cons of mechanical and electronic valves?
Any other cool upgrades I'm unaware of? (New timing chains, new tensioners, double chain systems)
What would symptoms of a failed injector be? How do you diagnose a faulty phaser/ vvt gizmo?
