My engine oil breather has blown out a quart of oil in the last 1000 mi. I have BB kit and just put in a Barnett heavy duty clutch. Since the breather hose comes out from the clutch housing I'm wondering of I put a crimp in the soft metal part of the hose that's inside the case while putting the clutch cover back on. Maybe it's building up pressure. I'm just taking wild guesses. I'm not over filling it with oil but tried keeping it at the minimum oil line and that didn't help. I have been cruising between 70 and 80 mph. If blowing oil is the nature of the beast than I'll live with it but if not, I'd sure like to know what might be the cause. Any one have any ideas? Thanks.
