It took us bitchin at Weltmeister before they finally decided the TUNA they where selling had some incorrect dimensions. Not sure when they are going to implement the changes, but none of them fit in the past. I'm not even sure we have any Garretson Tuna left on the shelves. I know we have pieces...

Buy Daves.

I had to modify the weltmeister one to get it to fit. It's an easy fix with a cutoff wheel in the grinder.

It was a brand new Garrettson piece. Very well made. I would definitely do it again.

i just removed one from the 1.7. It never leaked. What was wrong with the tuna cans from welt? Which dims were out?

also, when I removed it there was the pickup tube, the can itself, and a bushing in the tube to hold it on the pickup. Am I missing anything? Can I use a stock gasket to seal it?

thanks,
dr

I did not think the oil pickup was in the tuna can. Is that a modification? Did you eliminate the screen?

I thought the pickup extension was part of the tuna can. Puts the intake for the oil lower down in the case.

And yes, my tuna can had no screen. Don't think you can use the screen with the tuna can.

Without the extension the can won't function like it needs to. The extenstion drops the pickup down into the oil.

I've only run the Tuna Can, without any pressure problems. I worried about turn 17 at Sebring, but no problems.

The problem is that they changed suppliers at one point. The new center "bolt" was too long (it actually has internal threads, so I think it's really a nut but it looks like a bolt) so you could never get the can up against the bottom of the crankcase. You can probably cut off part of the bolt, but...

We bitched at WM and they started sending us the proper parts. I think, but am not certain, that the kits with the too-long "bolts" have worked their way out of the supply chain.

I don't recall the exact size of the "good" versus the "bad" ones.

Pelican can get them for you, as can just about every other supplier of aftermarket Porsche parts. Almost everyone carries Weltmeister stuff.

Jake hates the tuna can, but in a rear-engine'd application it seems to be a lot easier to scrape the bottom of the motor against something. (Which will trash the crankcase if it's got a tuna can on it.)

My problem was the pickup tube was too long. I cut about 4mm off of it and it worked fine.

You need the pickup tube because without it there is NO POINT! The idea is that when you are cornering really hard and all your oil pisses to the side of the oil pan - there is still a little oil trapped in the tuna can. The longer pickup tube is the straw through which the engine slups its milkshake (oil) from the resovoir that is trapped in the tuna can.

You do lose the stock screen, and it does use the stock gaskets - although an extra copper crush washer (I think it might be the same as the drain plug) is used to seal the bottom nut (as dave said - it looks more like a bolt - has threads on the inside).

When you install this thing BE VERY CAREFUL NOT TO OVERTORQUE THAT NUT/BOLT. Apparently this will cause breakage of the piece in the engine (windage tray??) which means you have to separate the case halves to repair it.

according to jakes video, it can actually crack the boss in the case itself. so the case would be toast.

If the can works as you've described it, and I think it does then it is useless if you are in a big sweeping corner.

The additional oil that is stored in the tuna can probably can't sustain oil pressure for more than a few seconds.

This must be why most production 914 racecars have an accusump or have gone to a dry sump arrangement.

Thanks for the revelation.
