Hello all. I have a 2005 TJ with 90k that has had two engine issues that have driven me #$%^ing batty. First- tick-tick-tick on cold start-ups. Not a daily occurence, typically have it right after an oil change. Second issue- and this has only happened several times- on a cold start, the oil pressure reads ZERO, then dash starts panic-beeping. Restart the engine and oil pressure reads fine.
So after reading and catching that both of these symptoms are related to this OPDA issue, I'm going to replace the assembly, Mopar PN #53010624AC. Yes, I realize that just replacing the whle thing won't totally resolve the issue, but I drive it less and less all the time.
Anyways, replacement... I see the wheel and housing are pinned together from the factory. I'm assuming this represents the engine at TDC? So I can remove old one, set to TDC, then install new one, then remove pin?
