RE: 120 lehman oil usage
Motion30-
Check carefully around your engine for oil leaks. Many Lehman 120s have some oils leaks. Common areas are
back of eninge near the heat exchanger - could be head gasket or the head itself.
stbd side front motor mount - could be from fuel injection pump. Cant do much about this one.
Rear seal - oil will accumulate in bell housing and drip out the very lowest point. You MUST be sure you have the bolt out at the bottom of the bell housing to drain this oil. This is a Bob Smith recommended maint. action.
Fuel Injection Pump - common oil leak area. Only two bolts clamp the pump to the engine block. Common leak area.
Oil diapers under the engine will tell you about oil leaks and show you where to start looking.
