So again, working on a 2001 873G with about 2100 hours. Got it up and running and notice it may have some blow by pressure. Any good way to determine how much is bad? Any way to alleviate it without a complete tear down? I do not know the history of the machine, but guess it may have been sitting for some time. Seems to run just fine and some light smoking, which seems normal for the Deutz engine.
