I got a brand new BB engine and am now seeing blow-by smoke coming out of the crankcase vents on top of the valve covers. This engine has less than 1000 miles on it. There is no PCV valve system, just a filtered vent out the top of the valve covers. A guy who is troubleshooting the problem is coming out tomorrow to put a flowmeter on the vent to see if the blow-by is excessive. Personally I don't care what the flowmeter says, having oily smoke fill your engine compartment with crud and having smoke coming out of your hood scoop at a stoplight is not acceptable. Am I out of line here? What is a normal reading from a flowmeter when checking blow-by? Should there be any blow-by smoke at all? The engine seems to be operating normally with no noticable (by the seat of the pants) loss of power. There was no blow-by smoke when the engine was brand new but now there is, I suspect a ring/piston/cylinder problem where a tear-down is required to troubleshoot and fix. Comments, ideas?
