I developed some leaks which I believe are pressure related. I have a 14x with 3700 miles and has never leaked until now and no it was not over filled with oil. It's leaking from the front of the pan gasket above the oil filter. When I went to clean the area to apply some flex seal to try and stop the leak, I noticed about a 2" piece of gasket (appeared to be rubber) pushed out. I also had oil around the vent hose that comes out of the rear cylinder, all hoses attached to the oil separator and some oil in the air box. My thinking is the check valve in the hose going from the oil separator to the top of the case is stuck which allows the separator to fill with oil and cause pressure. I've read several posts about different ways to vent the crankcase better, such as thicker longer hoses, catch cans etc. What I plan to do is replace the check valve and add a catch can/oil separator. The catch can has an inlet line, outlet line, drain line and air filter. So my plan is to attach the hose from the rear cylinder to the inlet the hose going to the airbox attached to the outlet and the hose coming out of the top of the case attached to the drain line in the catch can with an inline check valve. Does this sound right and would this setup be any better than stock or should I just replace the check valve and be done with it?
