73 oil tank recommendations please

[rockreid]

hello, my 73.5 Targa (CIS engine) oil tank is beyond repair and I am in need of another solution. Is there an aftermarket oil tank that can bolt right in? I am not so concerned with keeping this particular car all-original.

I have a 1973.5T that had oil tank issues! Just what is wrong with the tank that it is "beyond repair"? I am not sure if an aftermarket tank is out there, but if you go onto Ebay or check the Porsche salvage yards you will find a repalcement.

I had oil leaks whenever the oil level rose from heat. It took awhile to isolate the location(s) of the leak. It turned out that the two welded bolts that support and connect to the car body had stress cracks on the small support brackets. Hardly noticeable. I had these re-welded and I refurbished the tank after a good cleaning.

Try to keep the 73.5T as original as posible. It will pay off in the long run.

Not really. Just buy a used one. Cheapest solution is the best one.

I have an early 74 tank, the only difference being a slight depression where the impact bumper is designed to move back. No difference in oil capacity or function. PM me if you need it or pics for confirmation.

Pacific Oil Cooler kicked mine out the door saying it was too rusted on the outside. I already had a local machine shop clean out the interior but wanted to be safe and do an ultrasound cleanout. I guess that's not going to happen. I would like to somehow salvage what I have but really don't know how to go about doing it.

I've read that a radiator shop may be my best option. I don't know of any radiator shops in my local area (New Canaan CT) that will touch it. Any help there will be appreciated. Maybe I'll check into that as I would like to keep as much original as possible (this is a boxes-of -parts restoration project).

I can't supply pic of the oil cooler right now as it is still at pacific oil cooler being boxed up to send back to me.

I just checked Ebay "porsche 911 oil tank" and their are a bunch of tanks for the 74, one as low as $206.00. This might be the best and cheapest solution if indeed the 74 can go into the 73.5T. Many parts from the 73 crossed over to the 74 model. Make sure you look carefully at those support brackets I mentioned as they take the weight and vibration.

Good luck

Are'nt these tanks made of copper?
If they say its "rusted", a bead blast and POR15 coating will take care of the problem. I took mine to a radiator shop to be cleaned inside and outside before re-welding the support brackets and applying three coats of POR15 gloss black. Its like new.

They are not made of copper. The factory coated them in copper for a cheap (expensive today) form of rust protection.

I would certainly sell my spare for cheaper than $200. One would need to make sure all the inlets/outlets were the same.

[rockreid]

I guess I'll have to wait until I get mine back and see what some local radiator shops say about it. I already have a POR15 gas tank repair kit sitting unused . I supposed I can use that on the outside if need be after I check for any pinholes or other leaks. The copper paint on the outside was coming off so I suppose a bead blast would be a good thing to do to clean it up.

Call Dan Jacobs shop, speak with Dan and see what he has to offer. May be as simple as a ride to Oxford, CT. If has nothing ask him for Axel's # down in Madison area, I bet he does..

I have an 86 tank in my 73 so you should be able to use any tank from 73 on up.

Here's a 74 tank I have listed for $100. All the paint is coming off to reveal beautiful copper. Easy restoration by yourself.

modify a '72 tank for more capacity and re-locate the oil tank to where it ought to go

spendy, but the best for a sports car

or, be cheap and buy a used one - clean & paint carefully before installing & replace the nylon buffers; replace the S hose too

[manbridge 74]

Shaun's looks like it has been in a fire, lol. I'm sure it would work fine.

Regarding S hose: make sure the new one is an old good one or new, stiff OE spec.
