cold start engine knock
Hey guys,
I have an 02 F250 SD 4X4 V10 with only 40K miles on it. Lately when I cold start the engine, it sounds like the bottom end is knocking until the correct oil pressure is reached along with total lubrication. If I turn the engine over just a few cranks without actually starting the engine first, it doesn't happen. Any ideas? I do have an extended warranty, 7 years or 100K miles.
Thanks....

Any filter that says it replaces an FL-820S has an anti-drainback valve.
The one thing I noticed when I first changed the oil on my '01 was that the owner's manual calls for an FL-820S - not a plain regular FL-820
The "S" is for silicone anti-drainback valve. The Fram XG and TG series have them, the regular PH doesn't.
I've been using Fram for going on 25 years now - never an issue. My brother-in-law sells them wholesale to boat mechanics in the tri-state area, and never had a warranty claim. The rest of the filters he sells, he has. Go figure.
Anyway...
Ron, if you pump water up a hill, and turn the pump off and leave the valves open, does the water flow back downhill?
