What is the difference between the 180 HP O-360 engines from Lycoming and the TMX O-360 engine?
The two engines are both parallel valve O-360 180 HP engines. On the outside, they both have the same footprint and other than paint scheme, you would be hard pressed to see the difference between them. Internally there are some differences in features between each of them. The TMX engine differs from a standard Lycoming Engine by including the following features internally: *Pressure spray camshaft lobe and tappet face lubrication on standard cam engines, provided from dedicated oil nozzles, to help prevent camshaft lobe spalling issues common to Lycoming style engines. *Dynamically balanced VAR crankshaft for engine smoothness and durability. *O ringed thru both passages in the crankcase to prevent the common thru bolt oil leaks that occur later in the engines life. *Camshaft bearing bore, oil pressure relief notches machined in the crankcase to prevent the common Lycoming backbone oil leak, later in the engines life. *Nickel Carbide Cylinder bores on standard cam engines, for rust p
