[quote=”Timinglight” post=151237]Hello Eric
Thank you for responding…
I didn’t install it yet but I wonder does it leak through the valve or the fiber washer included?
I planned to install it with a copper crush washer.

If it’s a fiber washer, then based on my experience (not with such a valve, but with a bolt filling an unused oil level sensor on my ranger’s 3.0 v6), then that will leak (not so say the valve wouldn’t either). Due to the filler bolt being custom (Ford OE’d the pans with and without the sensor for my application, and the pan was a NOS ebay find), I was somewhat limited on what I could find for a seal. My most recent attempt was such a fiber washer, and it’s seeping just as bad as the crappy oil pan gasket that I replaced when installing said pan. You’d think it would work more like a paper gasket, but at least for me, fiber washers don’t seal oil ports.
(FWIW, I’m running 5w-20 Ford Motorcraft synthetic blend).
That sort of a valve scares me… One bad run in with some road debris, pop goes the valve, and bye bye oil (under load most likely too!). Unless you have a reasonably protective splash sheild or skid plate under it, in which case I see why a valve might be nice; I used to drive a Dodge Durango with a leaky front differential that resulted in a skid plate packed with oil based mud… to suffice that was a real PITA to clean out.
