2005 Jeep Rubicon LJ 4.0
2nd Gen without test port on fuel rail
Initial issue is jeep threw a camshaft position error SEL illuminated engine code P019
engine would not rev past 2500rpm would loose power studdering suggesting timing issue
idled like a kitten no engine noises etc
shop #1 replaced crankshaft position sensor, camshaft position sensor, TPS sensor, verified flywheel was not missing teeth, & OPDA
shop#2 Auburn, WA Jeep dealer Raped (charged) me 2K for a new PCM install (BBB ~ Complaint ID: 12445933 & Complaint ID: 12466326)
• Issue still remained
I wanted the root cause to be fixed which is why I took it to pros vs just throwing parts to try to fix issue
but instead I paid about what the root cause would have cost me figuring out the issue
I myself then swapped out MAP sensor, verfied 02 sensors, CAT operation & fuel pump then retimed OPDA
noticed it was wayyyy out? hmm
Started jeep up & it ran flawless until I let engine compression slow from redline
would not start & lost its time again
pulled shop #1 replaced with less than 1K miles on OPDA & noticed significant wear
somthing was causing this?
oil pump drag?
oil pump OPDA interface?
then noticed cam worm gear was severly worn -jumping teeth?
looks like I need a new engine :-/
Im concentious of keeping matching numbers for classic car status as I bought the Jeep new & rebuild OE block, buy crate motor, or just trade up to JK but dont like dimensions of new jeeps
