Description: Here’s an indepth teardown on the Honda Civic’s R18 1.8L 4 Cylinder engine. In this video we take a 2008 Honda Civic’s engine and tear it down to examine just what causes these engines to fail and why you should avoid buying a car with these motors. The engine has a very mechanically simple layout – a single overhead camshaft with no variable valve timing, a simple single chain timing chain layout with a hydraulic tensioner, no balance shafts, and an i-VTEC system in the head for economy. Common issues on these engines include valve cover and VTEC solenoid leaks, however 2006-2008 model year Honda Civics also suffered from cracked engine blocks. The area in front of the engine (exhaust side, beneath the catalytic converter in the engine bay) between the cylinders would develop a hairline crack between the outside and cooling jacket. The engine would start to leak coolant, and eventually overheat, possibly warping the engine head. Honda extended the warranty for 10 years on these cars, however that’s long past and many of these vehicles still exist on the roads today. Some have resorted to using JB-Weld adhesive or welding the aluminum, but that only proves to be a temporary fix since the cooling jacket experiences cycling heating and is internally pressurized. The only solution is to replace the short block with a new one, or one from a used car, 2009 or newer.
