When we got the boat 6.5 years ago, the PO had somehow added gasoline to the diesel fuel. The engine would start easy and run stong-ish until it warmed up. Then act as though air had gotten in the fuel and die. No amount of bleeding would restore its operation. During the first year it was difficult to get a feel for "running good". The first winter we hauled out to have the rudder rebuilt. Second year was fine but small air leaks and an ineffective means of venting the fuel system continued to occasionally plague operation of the boat. Second winter we kept it in the water. In the spring, we started the engine to bring it over for a short haul. The dipstick blew out and sprayed oil while the engine continuing to run, albeit rough. We made it to the travel lift just in time for the engine to die. 1 week later after being relaunched the engine would turn freely but not start. I found that cylinder 1&2 had low compression and have since assumed that they had stuck rings. The prevailing theory is that the water lift muffler push/pulled moist air in/out of the engine as the boat rocked all winter long. Eventually, the application of penetrating oil in the cylinders was able to finally work the rings free. The engine ran well but still showed signs of high crankcase pressure caused by excessive blow-by. The dipstick could blow loose and the breather would accumulate a lot of oil. I installed a breather catch can and accumulated almost 1/4 of the volume in the first year. We run about 50 to 75 hours each year and since the stuck rings 4 years ago the accumulation of oil has subsided. The can is still 1/4 full. I've rechecked the compression and now all cylinders read high and equal. IMO poor maintenance by the PO contributed/caused most of the problems I experienced. My use of quality oil and sample analysis has contributed to the reversal of the poor operation. The only additional additive that I use if Opti-Lube XPD but it is a fuel additive not oil. I swear by it.
