Quick Draining Oil Valves

[drrust]

Has anyone installed a quick drain oil drain valve, such as a Fumoto? If so how does it sit (Stick down past sub frame)?

I once replaced an oil drain plug that had been scraped by pavement, and that was with the car at stock height. I'd be worried if a spout was hanging any further down.

Not advisable. There is nothing down there to protect it should you scrape it on a road hump or accidentally hit debris. You'd be left wondering if it sheared off and drained all your oil out onto the highway... No thanks. Just unscrew the drain plug like everyone else.

I did not think one that would be protected waa available. Was talking with an RX8 owner who had described having to change oil every 1,000 miles. Said installing a Fumoto made his life easier. It seemed to stick too far down for my comfort level.

Why does the OP need one?

If one were available, it makes oil changes extremely easy (no tools to drain oil). On higher vehicles one can even drain without jacking vehicle up. Apparently they are popular with S2000 enthusiasts too.

I doubted they would work on the S65, as they stick down a bit. Wondering if anyone has used them.

Anyone who has changed oil on one of these cars knows it is not a good application for a fitting hanging below the pan. If it got hit, you could lose all your oil. A side drain like on an E36M3 is a possibility, but I have been changing my oil for 25 years without a problem.

Well the problem is, on 'most' vehicles the drain plug sits at the bottom of the pan BUT, parallel to the ground. So there's almost no worry regarding debris being able to damage or break off the drain valve.
Even E46 Engine have them that way.

The problem with the S65 is the drain boltS are on the actual bottom of the oil pan, and face vertically towards the ground. Which could/would allow the valve to stick below the sub frame and anything as easy as going over a speed bumps could knock it off.

So.. unless you can fit a 90 deg angle adapter on it, i probably would just deal with the bolt. Even with the adapter, depending on how low it sticks, i may not still want to do it that way.

They do make one with a 90 deg fitting. Which is what Fumoto recommends. I still think it would sit too low. I won't be experimenting myself but if anyone would like to, please let us know.

At least this is not a thread on rod bearings!

[C-los]

Well, i almost typed, if your drain plugs gets knocked off, you'll have a real reason to worry about rod and every other bearing in the engine, hahahah

You would have to be really confident it was protected. Otherwise it's not worth a little convenience to the oil changer.

meh, nothing is 'really' protected. a 2x4 on the road can snap an oil pan but, doesn't mean i'd look for trouble either. haha
