Champ Labs makes the filters for RP.
If you contact RP, you may get them to send you a new one.
If intermittent, is it most often after still a long while? I assume you know about cam phaser and timing chain tensioner noise issue on the modulars, which could be an issue independent of the filter/ADBV.
I know about the cam phaser issue, I work at a Ford dealership in the parts dept. The guys in the shop also thought it might have been the filter as well. We have not seen an 09 or newer one in the shop with the cam phaser issue.
I just sent RP an email,so I wonder what they will say.
Hello,
I own a 2009 Ford F-150 w/5.4L engine and I gave one of your oil filters a try.I believe that it has a leaking ADBV valve as i have a rattle now on start-up.I do not have a delay in oil pressure and it is intermittent on the problem.The truck has 14K for miles and have had the guys out in the shop look at it and they also think there may be a problem with the oil filter. Would you like me to return this product to you for a refund? I purchased it from a Pepboys out of state as there is not a dealer in Kansas and it would be very cost prohibitive to send it back to them, or am i just out of luck and on my own to get this problem rectified?
