started up the truck twice today and both times had a few knocks or noisy dry lifters. after a sec or so the noise would quite down. i check the oil and it was about half way on the good range. i used kn oil filter and either valvoline or castro fully synthetic 5w-20. any idea or potential problem i know its a pushrod engine.

 

I changed to Motorcraft filters fl820s and haven't had that noise come back since the change.

 

you think its the filter? i would think the kn filters wouldnt be that bad.

 

Filter issue,I had same thing happen on a WIX filter.Nothing being hurt by the noise but its a drain back issue with the filter.Kinda unusual also being that the filter hangs straight down and shouldn't be able to drain.But it does.

 

I use the FL820 filter also because of the design and material used in the backflow check valve, but in the vertical filter position, there should be no backflow issues.

 

Shouldn't be but there was with the WIX filter I used.Next filter change I went back with a factory and start up noise was gone immediately.Amsoil and Wix wanted the filter back for inspection as I had called them.Then I got lazy and tossed it in the trash.I had cold start lifter noise as soon as the WIX was used.Not so with whomevers the factory uses before and after the Wix.

 

The lifter is what failed in my truck snapped the head off, did all kinds of damage,it's been a nigthmare dealing with Chrysler about it .

 

hemi mike what filter did you use?

 

Whatever was put on at the dealer it only had 7000 kms on it when it went.
