My valve cover has a crack in it and is leaking oil. I can not find one for my 1981 124 but have found one off of a 1978. Will this fit mine? It looks the same.
Thanks

It cant do any harm to try it and see if it fits.

I am guessing it is aluminium so you could try this http://www.frost.co.uk/automotive-welding-tools/lumiweld-kit.html

I have used it to repair the bottom fork on a motorbike shock absorber. After 10,000 miles it is working fine. It has also been used to repair a VW van gearbox mounting lug.
