Yesterday I replaced my 05's OEM OPDA (it had an '04 date code inside its housing) with a new Crown unit. I have not had the barrel of monkeys noise that I could recall, so this was preventative maintenance.
I followed the usual steps found in all the tutorials and write-ups, used the original cam sensor, got everything back together, and (holding my breath) the Jeep started up and ran until normal operating temperature with no codes. I didn't have a chance to test drive it last night. I should be able to do this today. I will say, I don't think I have any valve/lifter tick now. It was always minimal anyway, but my ears couldn't hear any.
As with other projects where I encounter minimal hiccups, I'm skeptical I did everything right. I read horror stories and I didn't (so far) have that type of experience. (The worst of the project was cutting a slot into one of the old OPDA's cover screws because the T25 rounded out due to the angle of getting a tool in there.) I can't be the only one who doubts themselves after doing this stuff, can I?
I found the similar type of wear on my old OPDA everyone else reports; but the cam did not look similarly worn.
