Hello,
I'm new to late model Crown Victorias, but not to cars or wrenching. I've been building, modifying, fixing and racing (mostly Mopars) for 30 years. Decided I wanted a P71 when they started flooding the market for reasonable $$$. This summer, I got a retired squad car for cheep which runs/rides/drives great. Makes a whining when cold since I picked it up (cold start, not necessarily cold day). Also makes the usual 4.6 rattling from the chain guides until the pressure kicks in. I was going on the whining being a tensioner/idler pulley or the p/s pump. Being as it's hot and muggy as hell here in GA for most of the year, I put off messing with it until the other day. Put 3000 miles on it in the meanwhile with no problems. Long story short, it is not any of the above. I isolated the noise to the oil filter base/oil hose port housing with a stethoscope. I have to assume the noise is coming from the oil pump, or possibly the relief valve. Noise gets quiet after engine warm-up. Engine is filled with factory recommended 5W-20, although @ 100,000+ miles, I'm thinking of switching to 5W-30 or (OH MY GOSH!) 10W-30.
My hopes that this engine was like a big block Chrysler, upon which the external pump can be swapped in about 5 minutes, were dashed when I read the 164-step process for R & R pump in the Service Manual. If I have to break down the entire motor just to swap the pump, I'll just drive this one 'till it explodes, then buy another P71.
Any thoughts, similar experiences, or suggestions?
Thanks!
P. S. - I tried joining crownvic.net, but that seems to be a more arduous process than swapping a 4.6 oil pump... |
