Oil Pan Leak

Ok. Search revealed no pertinent results.

I have a leak from the back (towards the bulkhead) of the oil pan. I have dropped the pan and checked if it's level. Ok there. I cleaned the mating services and used the recommended sealant and torqued to spec using the correct torque sequence and ft/lbs.

Damn leak keeps coming back.

Where can I get uncut quality gaskets (e.g. a sheet 2 ft x 4 ft of good gasket material to cut to specc)? I would like to drop and reclean the pan and trace the pan onto a proper gasket, and use that instead of sealant in a tube. Worst case scenario I'll just pop for a new pan as well if the old one doesn't check for level.

I am open to any and all suggestions.

TIA,
EWS

Any chance it is leaking from somewhere else and running down the back of the pan???

I don't think so. The rear main looks Ok and the heads were just re-done about 3k ago. No leakes that I can tell. That's what's so frustrating!

I have the oil pan off the crappy 3.9 if need be, but If there are no gouges in the bottom of the engine or the oil pan matting sure face and the 2 are semi flat I would thing it shouldn't leak. You could always throw some Right Stuff on instead of the gasket to seal it up, I think it's kinda standard practice to do it as both of the engines I have had Right Stuff and no gasket.

Use Right Stuff. I have done this now 4 times, never with a leak. Stuff is great. No gasket.

Well I'll try the Right Stuff. I think a proper hand made gasket traced from the pan would solve the problem once and for all though,

Thanks,

There's no substitute for The Right Stuff, even a proper gasket doesn't seem to work as well.

The Rover V8s have several common oil leaks from the back of the blocks. There are 2 oil galley plugs that can leak (not common), there is a cam plug (very common leak), rear main seal (common leak), the 2 rear main cap side seals (very common leak), and possibly a porous block casting (seen a few). Right stuff will do a better job than a cork gasket and is capable of filling some pretty impressive gaps. Use it according to the directions...more is not better! If you have to have a gasket, I believe that you can still order one for a D110.
