85 911 oil tank drain valve wanted

[Len 911]

OK , Does anyone no what the thread size is for the oil tank. I have a 1985 911 3.2 euro model .. looking to use a Fumoto's drain valve kit but do not know what size. I called Pelican but they did not know, and what they have only fits up to an 83.
any only have one on an 85 and what part number to use.

Thanks
Len

The plug threads are all the same size, the wrench size change.

What is the thread size. And why does pelican say on there site it does not fit an 85..only up to an 83..

Thread size is M22x1.5 Do a search for Fumoto on the forum and you'll see there's been years numerous discussions on using these valves with good success

This is just one of many many threads Oil Valve for Changes

The up to 83 statement is odd because the oil tanks are basically the same from 74 to 89. You can even go beyond 89 and find a use for it. I suspect the up to 83 statement has to do with how the engine case changed from having a removable sump plate (with vertical drain plug) to having no sump plate and only a horizontal drain plug port.

I would not recommend using the valve vertically on a sump plate because it would hang down low and could get knocked off, emptying the engine of oil.

The FG-7B N series (hose nipple version) is available here for $26.95+ship (be sure to chose N series)
Our host does not offer this variant._

I got one from these guys, like the ability to attach a hose for draining and prevent a lot of oil splashing.

Thank you everyone,

Oooh that hose nipple version is cool.

[KTL]

For those who subscribe to the overkill approach, this Aeroquip fitting is pretty cool too. I've used it on Peterson oil tanks.

Unfortunately a bit expensive because you need the complementary female fitting to plug in

Super idea! The place at UWANNA's link also has a good price. I just ordered one. No more splashing as I will be using a short hose on that nipple.

I have a Fumoto on mine with great success. Definitely get the nippled version so you can slip a hose over lest there be a less minor Exxon Valdez waiting to happen.

Is the loss of the magnet in drain plugs a concern ?

[shadowjack1]

loss of the magnet can be overcome by placing a magnet on the outside of the tank just next to the drain. As you drain your oil remove the magnet. My theory is the fast draining oil will sweep away the metal findings. Replace magnet after the oil change.
