Symptons:
1. Clatter when starting cold then settles down when the oil pressure gets up. (Sound like the timing chain rattle. They were replaced about 18 months ago 15k miles)
2. When the engine warms up I get a knocking that sounds more substantial than a lifter, but does not have the frequency of a rod knock. The timing of this knock is more in line with a valve. Until the engine warms up the engine sounds normal.
The engine is a 4.0 SOHC. I am using a Wix oil filter, and 10-W30 synthetic oil.
I have read some posts that mention using the Motorcraft filter for the anti drain back feature, and I am considering using the Motorcraft to see if it will help.
Any ideas?
