I hope someone can help. I had a custom chopper built in 2004 it has a Rev Tech 100 engine. I had new Rocker Arms installed. But the engine is leaking oil right underneath the Crank Case. I put it in the shop and they are telling me that the oil leak is the rocker arm casket the shop mechanic told me they have checked all over trying to find a gasket and he told me that Rev Tech went out of business and now they tell me that I would be better off and buy a S and S engine since Rev Tech went out of business and they don't make the gaskets for my Rev Tech.
