They avoid inlet system fouling, while maintaining excellent reliability with low maintenance costs. People who employ this first line of defense keep blow-by well and truly under control. There’s not too many around, but FTC Decarbonizer is one example that actually works.
It also needs to burn the fuel more cleanly to reduce exhaust soot production. Use a specific type fuel additive that actively burns off carbon and keeps the top ring area clean. Remove existing piston ring groove deposits by using a Flushing Oil Concentrate, that is capable of dissolving and dispersing those tough-to-remove deposits. How to reduce crank case fumes before fitting a catch can kit? Blow by can also be caused from too much city type driving, EGR valves sticking, turbocharger coking, faulty injectors, bad fuel or malfunctions with emission control equipment, so the oily fumes that a catch can removes, are not the only factor at play. Your first line of defense before fitting a catch can is to reduce the cause of blow by, which in turn reduces oily crank case fumes. Performance also deteriorates! And eventually engine life is shortened! Clearly, anything that increases blow by needs to be addressed. Carbon deposits form inside combustion chambers, especially around piston rings…and this increases blow by further. When blow by becomes excessive oil gets inside inter-coolers, intake manifolds become fouled with oil and soot. Some oil vapor is also carried with it, and it’s not a problem, until blowby gets worse. That happens even in brand new engines, and for environmental reasons, this excess sump pressure is directed into the air inlet system. why a catch can could be useful? When you should fit a catch can? What it can and can’t do to fix the issue?ĭuring combustion, a small amount of the burnt gases get past the piston rings (blow-by), and into the engine sump. But first, it’s important to understand…. These days it’s quite common for people to recommend a catch can, and rightly so! Separating the oil from crank case fumes is a great idea, as it is responsible for a fair share of engine problems.
