914World.com _ 914World Garage _ Weltmeister Tuna can

Posted by: Joseph Mills Feb 27 2006, 08:14 PM

I've put a few miles on my new engine and want to put the Tuna Can back on before the AX seasons starts.

I've lost my instructions and can't remember if it takes a gasket or not.

And am I correct in remembering that the big bolt takes a crush washer?

Guess I need to start a diary.

Yes, takes a gasket and crush washer. John

Thanks John.

I do remember the nervous part... 9 foot# torque.

Although I have a heavy duty oil pump which shows 40 to 80 lbs oil pressure, on some sweeping off ramps I noticed the oil light would come on. That light does not come on with the tuna can.

On another note though, I wonder what that light actually means as to what activates it. You would think that it would be an early warning device of some sort. I mean if you're actually suffering from oil starvation at that point, it's value is somewhat diminished.

Anyone know the answer to this question?

light activates at under 10 PSI

Let me show my ignorance on this matter.

If my oil pressure gage is showing 60# oil pressure, and the light comes on, which denotes 10# pressure, which one should I not worry about?

When I blip the throttle, my oil pressure gage jumps. It's pretty responsive. Certainly able to respond to a drop in oil pressure in the duration of a sweeping turn. Since the light and gage are receiving signals from the same sender, does this mean the "oil light" is super responsive and the gage is highly dampened? Or...?

Just curious.

That now makes two of us, although there are hundreds out there...

I know someone has the answer.

If the light is coming on and the gauge is still reading something, then you have a mismatched gauge and sender.

If it is a factory Porsche gauge, then there is a part number under the rim that you can use to find the correct sender. Call Zims with that part number and they will mail you the proper sender.

The oil light is ONLY activated by ...... Low oil pressure.......
so the condition exsisted or the lite would stay off.

After talking with Fred Hurst who spun a bearing in his 2270 I wondered about that in my car pulling 1.3 lateral G's . With Hassan driving and me watching the gage and light (nearly puking from the ride) the gage never waivered and light never came on.

Tuna can, blueprinted Melling high volume pump, oil cooler and usually run a "little" high on the dip stick.

Also my car stays pretty flat in the corners.
