If and when the time comes with my Aviad, I will be thinking seriously about the reinforcing "bars" to even the pressure against the gaskets and avoid the "pinching" effect at the bolt locations.:cool:

I've patterned and cut some pan reinforcements for a BB Chev in the past - but just for the corner locations. Doing the whole rail with what I have in the garage would be a big job. It would be nice if someone with a CNC machine or something could work up some patterns for some typical pans and market them.

Mickmate - are you out there??

I think I'll remove the pan, get some stainless bar, maybe 3/8" or 1/2" wide by 3/16" thick, lay it out over the pan rail, weld the joints, and drill. I don't think it would take me more than 2 hours.

I can't see oil in the bell housing but I am pretty sure my rear main is leaking.

Well, you are way faster than I would be!;)
Send some pics if you do it.

Any excuse to get that welder out!

Absolutely. I'm a welding fool!

Always show your work.;)

DanEC 01-13-2016 04:11 PM

Yes please - show us what you come up with.

Good luck.

lippy 01-13-2016 05:11 PM

May take me a couple of weeks, but you'll see it.

I think you should buy a seasoned iron block, then carefully disassemble your existing engine and transfer each part to the new iron block. That's the only hope you have for dealing with your leaks. Either that, or just put pie tins under the drips.:cool:

Here are a few pictures of what we came up with to try and help with the leaking oil pans.

Post 40 in the referenced thread for the time limited. I bet that does cinch the pan gasket up tight - very impressive.

Yes, VERY impressive. I have a pan from Armando's and I like it, but the pan rails could use something like that as they'd bend or distort far too easily without similar reinforcement.

Studs
 
I started using set screws for valve cover studs, after seeing them on a friend's race car. You don't really need high strength ARP studs with coarse/fine threads, and the coarse threads allow you to tighten them with more friction on the nut w/out collapsing the gasket.

I used to use ARP studs on the pan, but they kept backing out. I don't recall what I have on the pan right now. I know I tried using studs with silicone on the threads, but that was a long time ago, and I haven't been under that car in a while, so I just don't remember. The Cobra has bolts from a previous owner.

Sorry to ramble, just thought I'd provide a data point on studs vs. bolts.

Is that part available?

Detroit Bill: Are you asking about the pan or the reinforcing rails? If it's the rails I'd like to find the p/n as well!

cobrakiwi: You said it is - can you provide p/n for rails? Puhleez? BTW, my engine is 460 CID (385 series).

Detroit Bill 01-15-2016 10:05 AM

Yes, I am talking about the stainless reinforcing rail.

We custom make these to order:)
