My Tartan 27 #332 from 1967 was re powered before I bought it last January with a Yanmar which has been running great until a few days ago when I noticed some oil in the bilge and discovered the breather hose had worked itself off the nipple of the valve cover. When I went to push it back on the hose fell off in my hand and I struggled to discover where the other nipple went but eventually reattached both ends again one on the valve cover the other to a nipple headed toward the air intake silencer. After starting the engine in ran for 20 seconds then white smoke began exiting the exhaust and I shut the engine off. The hose did have a bend in it the may have restricted the flow. Any suggestions, I was going to replace the hose and try again today
