Most of the TCM powered (IO-470, IO-520, TSIO-520 and field retro fitted IO-550 series) engines installed in Cessna single engine aircraft do not have a check valve in the engine induction drain lines to close them off after the engine is started. As a result these open ¼” (diameter) aluminium lines which are connected directly to the induction manifold (one each side) and are positioned to overboard excessive priming fuel at the inboard sides of the cowl flap openings, just forward of the fire wall, enable large amounts of grit/sand/dust or whatever to be sucked up through them into the engines induction system and cylinder assemblies. (Just ask anyone who works on these engines what they find on the inner walls of the induction pipes.)
The ingestion of grit/sand/dust causes notable cylinder and piston ring wear. We have found that installing our in line filters, eliminates the injection of grit/sand/dust through induction drain lines and significantly reduces cylinder and piston ring wear. It also reduces spark plug electrode breeching and is a positive step to assist in obtaining the manufacturer’s published engine T.B.O. and improves engine reliability and safety.
Our TCM Cessna 206 & 210 owners generally don´t add any oil between their 25 Hr or 4 monthly oil changes
