Chapmar

Hi,thanks everyone for your input,engine has hardly any smoke on start up or running,it does’nt use a excessive amount of oil,it was changed from Morris Classic 10w40w to Morris Servol 15w 40w in the summer,the oil that appears from the exhaust / water coolant is a rainbow type thin film which probably looks worse than it is,but would like to cure if poss,thanks for your help.

Hi,I own a 28 ft Bermuda Bucanner with a bmc 1.5,have recently noticed oil in the raw water coolant coming out of the exhaust into river,although it is probably a small amount I’d like to stop this if possible,I have been told it could be valve seals and another person said possibly a blocked air pipe? I would appreciate opinions,engine is 1981 but regularly serviced.thanks.
