Hey guys, Im new to the forum but Iv been searching for answers for my specif motor (71' Evinrude Fastwin 18) and haven't found a thread yet so Im hoping I can get a little guidance here. I recently had as issue where the expansion plug on the piston head cover came out, well today I replaced the plug and since it was the original head gasket I had to replace that too. Now so far the expansion plug is fixed but Im getting small water leaks in a few spots along the edge of the head gasket. I know I need about 18-20 ft lbs of torque for the head bolts but I do not know the correct tightening pattern so I assumed this might be the problem. Or could this be cause by some other issue like the head gasket not lining up correctly? Because the garbage can I have the motor running in has a lot of unburnt oil now and it seems like the exhaust is a lot more smokey than it was before I had any issues. Any help would be much appreciated.
