Have a Perkins 4-107 in an Alberg 37. Engine has about 1800 hrs on a major overhaul. The engine is becoming somewhat hard to start, and is putting out quite a bit of "blue" smoke, and is leaving a slight "sheen" on the water. It seems to run OK and seems to not have lost any power. Could this be a injector pump timing problem? A set of rebuilt injectors did not help the problem. I want to explore any possibilities before we pull the engine. Any ideas are appreciated.
