Boroscope Examinations
A boroscope allows the technician to see the inside of a cylinder including the piston, cylinder walls and valves. Can be used to verify head gasket failures, bent valves, sludge accumulation and other serious problems.
Oil Analysis
Oil analysis can determine internal wear to cylinder walls, pistons, crankshafts, camshafts, bearings or other internal parts BEFORE symptoms are evident!
