Just picked up my '14 Roadster with 14,000 miles on it from the dealer for the second blown cam cover gasket, both times right behind cylinder 1 on the exhaust side. Dealer mentioned that Triumph was asking about modifications to the bike, and they kindly said nothing.
However, the tech came out to talk about what he thinks is going on. He said the cam cover and head mating surfaces are flat and clean. He thinks the problem is that I've removed the stock intake and installed the Ramair system. The stock exhaust design creates a vacuum to the crankcase which aids in pressure relief, and the Ramair crankcase breather filter doesn't do anything to help relieve big crankcase pressures, and that unrelieved pressure is what's blowing out my cam cover gasket.
I told him I don't understand how on one hand he can say the crankcase generates high pressures but on the other hand a filter won't allow it to breath. The filter has only been on a year, but I guess I'll check it to see if it's clogged or something.
Does the crankcase require vacuum-assisted pressure relief, or do I need to find another Triumph dealer?
