My Valve cover oil cap is leaking oil. Any recommendations on replacement? I found this one:

Valve Cover Oil Chrome Cap (Old Style) | MIC

This is the old style looking chrome cap that goes on the valve cover. The original ones are now made of black plastic material. This is a chrome-plated, highly polished GERMAN reproduction that fits M10 /M20 /M30 Engines. These are currently clearing customs and they will be ready to ship...

I think chrome looks really out of place in our engine bays. The gasket can be replaced. Suggest if you buy a chrome cap that you swap the gasket. or get one from Hal.
 
Years ago - I had a leaking oil cap in my 2002 (M10 motor). Back then, all I could get was the new looking plastic cap from the more modern motors.
I discovered that since the new cap fit my old motor, the gasket would also then fit. So I bought the new cap, put that gasket on the old (original to the 70's) cap and solved the leak.

That might work here also. At least it did for me back ... uh.... 35 years ago. LOL

could not be ideal
unless your material was NBR or VITON rubber
typical rubber is EPDM, and that will not stand oil and petrol

double check

I've seen that as well.

not ideal, but understandable
i have checked that usual new gasket is 3mm thick, with time and wear it reduces thickness and fuel vapours can leak, even actual fuel

this is best solution as sometimes leak occurs in the cap itself, the construction of the cap is an odd one as the internal tabs´holes could allow passing vapours passing the rubber through the metal to metal welding
