Have my first 914 with a "tuna can" sump and a front oil cooler.
Is the tuna can removed, cleaned etc. same as the stock screen during an oil change? Does it use the same sealing ring, compression washer as stock? Or do I need to find proper seal? Or should I just leave it alone?

I find mixing it with a bit of Mayo and a hint of relish works for me.

Bon Appetite..!!

I'd not eat anything made by a person who measures with a hint.

UMmmmmm tunafish samich (one under each armpit)

Me thinks you need to rephrase.............

Smells like fish...tastes like chicken

ooopps....wrong tuna

Jim Does it have a "coffee can" exhaust

Jim, maybe you should re-submit the ? in the morning. The mind altering "imbibments" will be diminished by then

.....

jimbo,

i have a tuna can to throw on my car (thank you paul heery ) and it appears it will HANG BELOW the engine bar. this scares me... my car is 3.75" to the donuts already...... so.... me thinks i need to grow some balls or raise my car to run it......



but.... the filter is eliminated i believe with the tuna can

I don't run them....

I'd rather run a deep sump- the amount of ground clearance lost is equally..

... disturbing.

FEAR the speedbumps with a tunacan. track-only application i'd wager.

Or if your 914 is in 4x4 mode (8" clearance all around). Then the only thing you have to fear is small wildlife and tree stumps.

Well, I run a can on my car. Street and Autocross. This comes up every once in awhile so I'll give my opinion again.
1st it came with the car in a box, So I put it on .... Hey looks cool NOT lower that engine bar. But it is nearly at the same location as the rear wheels so the car will lift as you go over speed bumps. ( I hate bumps) My car sits at 3 3/4 " at the lift donuts in front with 195/50-15 tires.

I got it to seal and I leave it alone. I cut thick paper gaskets like the ones you get from engine building seal kits. just drain the oil as any normal car. from the sump.

I have a oil coller also and figure dirty oil will still remain somewhere in the system anyway.

Related question:

How much torque do I put on the bolt?

I know too much=new case.

I ran one for two years on my blue car. Never had a problem. Never had a concern about hitting something unless it was high centered. Even when I slid the car over a curb it didn't touch the can. I just put on the car I just built for a friend. I think they are necessary for going fast.

Uh Oh, looks like Mikey is going to form a chapter of the SBDS. Well, you can liason with the CGBC & WLLLC.

WTF?

SLITS is off his meds again....

Is the stock screen in there? I would think that should be looked at once in a while. But I think Joe probably has the right idea. Leave non-leaking things alone. The car is a track only car although I may drive it there (10 miles) on occasion.

Bruce: you were right, as morning approached I got some helpful answers. Thanks all.

As I recall, it's recommended to not use the screen with it. I've had a tuna can on my engine for about 2 years with no problem.

The nut that holds it on does sit even with the engine bar and it is just slightly ahead of the front edge of the rear wheels, so you do need to use caution with speed bumps and some driveways. Not that big of a deal. Have you ever had an engine bar scrape a speedbump? I haven't.

I changed oil a few days ago and removed the can to see what I might find in the bottom of it. Nothing but oil.

I put it back on with a new gasket and now have a very small drip leak - no big deal, but somewhat frustrating nevertheless. I'll just wait til the next oil change (1500 miles) to deal with it. I'll continue to remove it once in a while.

If you have large tires that will generate more lateral force, and are autocrossing or like to do fast sweepers, exit ramps, etc, the tuna can will keep the oil light OFF.

huh?

i have one on my engine. it's not lower than the engine bar. seems to work just fine.

Joseph, did you use a homemade gasket? Or do the stock gaskets and crush washer work?
Hate to take it off to find out I wish I hadn't. Also, the other way around.

Car will be autocrossed regularly, occasional DE, with R tires and 7x15's, so I hope to experience some lateral G's.

I have one there is no screen inside but when I took it off it now leaks maby i should have used both gaskets that came with the kit. I will wait till my next oil chang to deal with it

The standard "sump gasket kit" contains the crush washer plus two gaskets--one for between the screen and the crankcase, one for between the cover and the screen. The "tuna can" does away with the screen (you still have the regular oil filter!) so you only use one of the gaskets.

Torque on the nut (yeah it looks like a bolt but the threads are on the inside, so it's a nut!) is the same as stock: 9.4 lb-ft. Yes, less than ten pound-feet!

The can does not, on my car, hang down as low as the engine bar. I understand that on a Bug (or other rear-engine'd application) it would be much more exposed to damage, but on the 914 it is right around the same fore/aft position as the rear wheels and seems to have zero issues. I have scraped my motor mount bar (!!!) but not the tuna can.

There was a bad batch (or two or more!) out there which had the oil pickup tube extension too long. With that extension, the can would never seal up to the bottom of the crancase, there was something like a 1/4" or 1/8" gap. You can cut material off the bottom end of the extension tube and correct that, but it is probably better to return the faulty parts to the place you bought them from and tell them to get the correct parts from Weltmeister. (Trust me, your retailers have already yelled at WM more than once about this!!)

Sadly, I do not know the lengths of the correct sized extension nor the incorrect-sized one.

Thank you Dave. I think now I know what I need to know.

I used one of the two gaskets that comes in the kit.

Next time I remove it, I'm going to use a bit of axle grease on the gasket (this works well for my valve covers).

Yeah, put some lateral G's on it and watch the idiot light not come on - but be careful to not run into anything.

Now that Dave provided the torque specs, I'm gonna see if I tightened mine "properly". Ten pounds is not much...
