A Real Solution to Engine Blow-by
Engine blow-by is the term used to describe excessive internal crankcase pressure – a result of inadequate sealing between the piston rings and the cylinder walls, particularly during the compression and power strokes of the crankshaft. During these strokes, generated compression and expansion pressures create extremely high pressure above the piston, and if the ring-to-cylinder…
Read MoreWhat causes engine blow-by, and can you fix it without rebuilding the engine?
Most of the time, yes. Blow-by is a serious mechanical problem, and if you let it go long enough it gets much worse. But in the majority of cases the root cause isn’t worn rings. It’s carbon. Hard carbon deposits that have built up in the compression ring grooves and on the cylinder walls are…

To answer the question “Does FTC Decarbonizer really work?“, take a look at these photos – This photo is of a cylinder from a Caterpillar 3508 diesel engine at 8,000 hours. It was used in an earthmoving machine in a large mining operation in Australia. It was torn down and rebuilt prior to the normal…

Sooty engine oil, carbon deposits, & blow-by issues Regular diesel engine operation, including starting, becomes increasingly problematic as combustion-related deposits build up on critical engine components over time. Cold weather only compounds the situation. Types of operation, such as excessive idling, short run time, light work, and city type driving, all contribute to carbon and…
