OK, so my car has a 3.0 with Webers. It has what to me appears to be a rather unusual oil cooling system:

Has anyone ever seen something like this? I have a thermostat installed beck near the engine and then this copper pipe running to the front along the passenger side long and looping back to the engine. I guess it worked.

Thanks.

Looks like a facsimile of the trombone cooler used on the early 911s. You could put some cooling fins from a hot water heating system on the pipes and get even more cooling.

Looks like Joe the Plumber owned that car! Does it work? Does it leak? If it works on a hot day leave it. Copper is an excellent conductor or heat. Car has a bumper to cover it?

According to the PO, it did not overheat, it does not appear any of the copper leaks. Yes; I have a bumper and valance but removed them to swap out the aftermarket air dam for a stock valance and have the under side of the car cleaned.

Keep an eye on the rubber/copper transitions and mounting brackets. Vibration can cause problems with copper work hardening and cracking. Otherwise, drive it!

Thanks; that is exactly what I plan on doing. Brakes, fuel, oil leaks and then drive. My goal is spring.

If you used a F/G Front Bumper, you could do some custom venting. The Trombone coolers were in a wheel-well, so they got air-flow.

I think the system could work very-well. Is is copper pipe all the way back to the motor?

It is copper all the way back to the engine. I plan to drive it to see how it works.

looks like it might be an easy change to a coil if need be,
but if those lines are solid you might want to consider flex lines to take the stress off the copper lines at places
copper gets work hardened and can let go
i have copper lines in my car but just up the longs

Is there any rubber hose between the engine and the copper pipe? If not, it is just a matter of time before they break, due to the engine movement relative to the chassis. If there are rubber lines in there somewhere to absorb the movement, then it will probably be OK at least for a while.
