Heater Core Valve Replacement

[dieselappnerd]

I just finished another backsplash of my oil cooler, and I did it back flush of the heater core at the same time. It looks like my vacuum valve for the heater core may be a leaking. I’m going to check the connections first, but I was curious if there is an aftermarket valve that’s better or if OEM is the right thing to do.

The OEM is not really know for a lot of failures.
