hi somon thanks for the heads up. i have just ordered a NEOPRENE gasket from a company on ebay. i dont know what the difference will be compared to the jpat one, but the supplier on ebay is a gearbox maual and autobox specialist only . so it should be ok , but we will see. it was about £4 cheaper than the cork version, which i was not over enthusiastic about. back in the day how many rocker cover gaskets can you remember with the leaking cork gaskets ? it would probably have been fine , but it just put me off a bit. ...
