Can I ask why having the oil tank reside in the left quarter is so critical? It would seem to me that it could live virtually anywhere in the car. Front trunk, rear trunk? Would that not take away from the complexity of building a very specificly shaped/sized container to fit in that odd location? Why not put it in the front trunk and add a little weight bias up there? You could shape it anyway you want and probably buy something off the shelf that would work for far less. Just my $.02.

The tank was put in the quarter behind the driver because that comes the closest to where it would be if the engine were in a 911. You could use an aftermarket tank and mount it anywhere you can find space. But then you have to run the lines to the engine. It has been done many times, but in my opinion, why reinvent the wheel? Porsche already did all the engineering, all I have to do is install it.


There have been multiple locations for the oil tank, some have installed in the stock location, some put it where the battery normally lives, and some in the front trunk. Some have even installed a 911 tank in the rear trunk.

I think a competent welder/sheet metal fabricator could use the oil filter console mount and fittings from a 911 tank to make a 914 tank. It would just take some time and effort.

a lot of race cars run it in the front trunk
the tank has to be high enough in the chassis to feed the engine via gravity
the front trunk is done often, yet there is still a miniscule question about the gravity feed and ability to meet the engines oil need with such long lines...

obviously lines need to be thought out carefully with a front trunk set up as well as size of those lines.... usually AN16 is considered optimal for the feed due to less restriction in the bigger sized line..... so AN16 from the front end can run $$$$ big big money! (possibly more than the cost of a stock tank)

finally... some racing sanctioning bodies won't allow the front trunk
may not matter to 99.9% of the people out there.. but in my case, my vintage organization will only allow stock location for the tank.

I want a clean install, I like the stock look, but what is hidden from sight is not my concern.

The reason I asked about the 930 tank is because someone is offering me one for my ceramic lifters.

Mark - I wouldn't do that trade. You're lifters are worth way more than any 911 type oil tank unless it's a plug N' play tank (i,e, real 914/6 tank). Another option (since you're going to the /6) is to put the tank in the engine compatment where the circuit board is. Witha carbed /6 you really don't need the circuit board. You'll have to add a couple of relayed power leads for things like the ECU but that's easy and can be put anywhere. It's amazing how much space you have in the engine compatment behind the driver once the board is removed.

I'm surprised no-one here mentions the PMS tank?
http://www.patrickmotorsports.com/part/434/

Seems exactly like what's being talked about, and fairly well priced compared to what others have been advertised for?

Must be some "inside reputation" or other "Motormeister" type scuttle butt keeping it off the list? (IMG:style_emoticons/default/confused24.gif)

Keep your lifters and make a tank. It doesnt have to be fancy, just make a torpedo that stands up at an angle and sits behind the fire wall once the circuit board is removed. You have the skills.

That's what I'm thinking. Mild steel I could make the tank al la brant very easy and cheap.

Guy doesn't have long to make a better offer, another member just offered me full pop on the lifters.
BTW I do have another set for my bug T4 engine (IMG:style_emoticons/default/smile.gif)

Is this a turbo tank? Dipstick starts off part # 930 XXX XXX....

Don't think I'm that lucky Doc, I know this tank has rust issues.

I'm using the PMS tank and have no problems. Got it about 12 years ago when there weren't many others to choose from. It has the later oil filter console for the later filter and the bigger inlet....

Do people with real /6's ever switch to a repro tank just to preserve the real one they've got or only replace it when it starts to rust/leak?

The stock tank is long and narrow. This is not a problem in most instances....
at autocross it can be. It gets to sloshing back & forth and oil gets caught up in the windage. I usually found approx 6-8 oz of oil in the catch tank after an event. If I didn't keep that tank drained I ended up with oil in the trunk....that happened twice & it's messy. Non-violent AXers shouldn't have a problem.
