my car is pretty low.... dont want to tag something with the case.....

speed bumps a danger????

im gonna throw on my welt tuna can this week

(BTW - paul heery rocks!)

IIRC the -4 engine crossbar is lower to the ground, and I never had problems with the tuna can when I used 'em. It did definitely help the high-g starvation issue it's designed for.

If you're going off-roading in a 914, then you have plenty of other stuff to worry about

I have had one on my street 2.0 for years. I believe the engine bar is lower than the "tuna" can.

just remember to take those speed bumps SLOW and AT AN ANGLE. The last two tunacans I took off of engines (those 2 of those 3 914 2.0 cases at my work) you can see the head of the bolt is bent a tiny bit and there's some serious scrape marks. Just be cautious from then on.

Ok, I've seen the term 'Tuna Can' and pretended I knew what people were talking about for too long.

What in the hell is a Tuna Can?

(Assuming that I know what a can of tuna looks like.)

It is a sump extension that bolts to the strainer plate bolt.
That bolt is only torqued to 9 ftlbs.
If you over tighten you ruin your cam.

You could plumb in a external oil filter in to the oilcooler stand and run a 977 oil filter which is about 3/4 qt cap or the other one The# slips my mind but that one is 1.5 quarts.
Either one will hold pressure in the system.

On my Rally Volvo 444 years back I ran 3 1.5qt filters to insure oil pressure at all times.

This was before the Accumulator tank they sell now.

Overkill yes but I never had a oil light come on.

Be sure it fits properly.

There was a while they made them impropely and they leaked.

I have a tuna can on my car, installed by the PO.

Anyone know where I can get a gasket that seals it to the base of the sump? Mine drips and I think it is because of the gasket.

theyre the same as the one for the stock drain plate.......

pelican sells 2 and a crush washer for like 3 bucks....

How would an oil filter hold pressure in the system?? They hold extra volume, true, but I don't see how they could apply pressure to the system. (If oil were compressible the way air is, I could see it--but it isn't compressible, much like water.)

If you want to keep the oil light out in the longer turns, a Tuna Can or an Accusump is the way to go. Accusump is better because of the much higher capacity, plus you don't have any low-hanging parts that are at risk. For "real" race cars that can see significant lateral Gs, especially big-track cars that can see those Gs extended periods of time, the Accusump is the way to go.

For an autoXer, which won't see the lateral Gs for very long periods of time, or for a street car on the track, the Tuna Can is just fine.

BTW, Raby has had at least one engine completely ruined when the Tuna Can caught on some external obstacle and broke off, taking part of the case with it. I speculate that this was in a Bug, though, where the bottom of the engine is at significantly more risk than in a 914.

Just for you Cpt!

I've "heard" that there's little chance of impact damage ....but I think I'll go for the accusump.

It was in a 914.....

The problem with them is the way they attach. I like the External sump much better because it has two very heavy bolts and a steel plate to attach it.

I have a newly designed extension being used in my 914 now, it has the absolute best ground clearance of anything available and attaches very securely....

I have seen many people use a Tunacan with no issues, but I don't care for the attachment method especially considering how weak that area already is in a TIV engine.

be creative--make a skid plat that attaches to the engine cross bar and attaches to the lower trans to engine bolts---make a hole in it so you can drain the oil----skid right over anythin----

So, a tuna can is a lower baffle for the oil pick up to fit in? I pressume that since it sits low with high walls it acts as a small holding tank for a small amount of oil as the car pulls g's and the oil goes away from the oil pick up?

Thanks for helping the rookie see the light.

you got it. it extend the pickup tube too.... so all the oil can do is stay in the can during prolonged HI-G turns..... ensures oil is at the pickup tube...

That is a great idea, Accusump rocks but is so expensive.

I wonder what Raby's idea looks like.

The Ideal Extension would be a theaded into the case at the sump plate not with the bolt with a depth of about a 3/4 of an Inch and about 6 inches in diameter.
Still risk knocking it off.

The accusump ... wierd... which of theirs is the unit preferred for 914s? The marine version? 1qt accumulator?

actually, i'm surprised how reasonable an accusump is. few hundred bucks is all it should take
