Who sels One way valve, Oil Filter for a 5.3l

[02-Z71-TX]

I am looking to protect my engine a bit more by using a one way valve oil filter. My toyota's oem filter was one way, but I can not find a maker for 5.3l chevy z71

Not sure on that one. Give this site a try Bobtheoilguy  There is a ton of information on here with anything dealing with lubrication and filters. Someone on that site probably know's something.  Heck from reading through some of their posts, they make it sound like the wal-mart filter is the best for the buck.

I think that all filters for the newer engines nowadays have the anti drainback valve, but I could be wrong. I use the Baldwin B-1432 filter and it has the Anti-Drainback Valve.
