Disadvantages of the EW7A engine
Bad fuel or oil cannot be tolerated by a reliable engine;
Usually, the injectors come first, followed by the candles and ignition coils;
Floating engine speed is caused by a dirty throttle or idle control;
Inadequate lubrication causes hydraulic lifters to knock rather quickly. Additionally, the oil here likes to seep out from under the valve covers and the crankshaft oil seal.
