Installed this valve the very first time I changed my oil. It makes it so easy. And when I buy new oil filters the guys at the auto shop give me wild looks when I tell them I don't need the crush washer. :D
Hopefully yours doesn't leak... Woke up one morning to oil all over my garage, the valve was closed but I guess it failed. Replaced it with the traditional bolt and washer, never had a problem since. Just get one of those magnetic oil change tools to take the drain bolt off.
Yeah, mine started leaking after I hit it with something on the road, unfortunate placement of the drain bolt on my civic. Idea is cool I agree, but it introduces more ways for a fail.
If you're reading this and are on the fence of purchasing one, don't. They are prone to mechanical failures and leaks, even with the most expensive ones. There's a reason most manufacturers dont include them; even the bleeding-edge exotic supercar and Formula one engineers don't use them.
It's not like all your oil will drain out if you don't use them, but they help seal between the pan and the plug, helps stop you from over tightening the drain bolt, and makes it a little easier to get the bolt back off for the next oil change.
I've never even heard of them. I think it's safe to assume that they aren't necessary. I don't even know anyone who has gotten a leak from their drain plug.
I had one, still have it in my bag and it's been terrific. The tubing and valve combo eliminated splash, spill, shoving my hand up there, etc.
The bad news is that it was just a smidge too low and I tweaked it off-road - I do have a skid plate but the bottom was pretty much in-line with the top of the plate so too close.
One oil pan later, I'm back with the bolt but only by necessity. I think I'll put a valve on my SO's cousin's Honda. The drain hole is horizontal on that one.
