Went to change the oil on my /6 today. Pulled the drain plug, removed the oil filter and let it drain for awhile. Cleaned the drain plug, installed with a new washer, installed and new oil filter and started filling.

At about the six quart mark the oil filler started to overflow. I've obviously missed something, but what?

Thx,

No, how do I do that? (We moved in the past six months or so and I still haven't found my 914/911 books, so I have no ready reference.)

You will have to break the oil line from the engine cooler, unless you have a different drain setup.

You need to undo one side of the line going from the bottom of the tank to the engine ...

Start over if it were me, I'm kinda surprised you got six to go in? I'd check the breather line.

There's a proper set of offset (and BIG) open-end wrenches for this job. When I was doing it, the factory was the only source (P-numbered tools) and bloody expensive. IIRC, i taped the jaws of some water-pump pilers (Channellocks..) for the 'big' and stationary end, and used some kind of adjustable wrench on the 'movable' end.

Use care if you're doing this in your driveway because 1) the oil will drain from a 30mm hose at an ASTONISHING (i.e. FIREHOSE) rate and 2) there isn't much clearance and you stand an excellent chance of scraping your knuckles when the fitting finally gives way (I still have the scars...).

I'm wondering... Do I need to drain what's there now so it doesn't come out some breather tube in the next week or is the bottom end just going to be bathed in a lot of oil for a few days?

Yes, start over.

Pull the drain plug from the sump and drain all the oil from there. Then break the suction oil line in the middle. The factory provided a fitting that is in a bracket just in front of the left rear wheel. Have a big pan for this. Once it has drained, reconnect the line and put the plug back in the sump. Make sure you use a new crush washer on the sump plug.

Now fill the tank with 9.5 quarts of oil. Start the engine and warm it up. Then check the oil level with the engine warm and idling.

Thanks, Phoenix, for the link to the oil line wrenches. Just ordered a set.
Changed oil about 2 weeks ago and had to use pipe wrenches, which don't fit very well.

I don't understand what's so special about the P242 wrench set. Can't appropriately sized open end wrenches do the job?

Yes - but the 'special' tools have the ends indexed just right. There isn't a lot of room to work under there with open-ends that give you just 6 indices. They're a lot nicer - not necessary, but a lot nicer.

Do you have proper sized open end wrenches? Most don't. When you price the proper wrenches these are a bargin. And... you need them.

You can probably get the two you need here:

Clay mentioned a VERY important point. Only put in 9.5 qts. No matter what the dipstick says. I learned this the hard way. You fill to the level while it is warmed up and running, otherwise it pisses oil everywhere (IMG:style_emoticons/default/dry.gif)

Not all tanks are the same (IMG:style_emoticons/default/poke.gif) Then there are those with oil lines that are longer and then those that have coolers.

But yes, if you over fill it makes a BIG mess (IMG:style_emoticons/default/huh.gif)

The point is, if you fill it to the full mark while it is cold, when you start it it will piss oil through the vent into your intake. (IMG:style_emoticons/default/wink.gif)
