Disadvantages of the Honda K20A engine
The exhaust camshaft’s rapid wear is this engine’s most well-known issue.
Unadjusted valves can also be the source of knocking under the hood.
Idle speeds frequently float here due to throttle valve contamination.
Additionally, the engine mounts are short-lived and the front crankshaft oil seal frequently leaks.
Localized overheating of the fourth cylinder plagued the engines during the initial years of production.
