Disadvantages of the EPE engine
Although these power units are robust and dependable, their age is noticeable;
The engine has undergone numerous modifications, and some spare parts are extremely hard to locate;
This engine’s carburetor-equipped versions are particularly troublesome to operate;
The rear crankshaft oil seal frequently leaks at high mileage, and replacing it is costly; outdated or subpar antifreeze significantly shortens the pump’s and thermostat’s lifespan.
