Disadvantages of the EPE engine
- These power units are reliable and very hardy, but their age makes itself felt;
- The engine has many modifications and it is very difficult to find some spare parts;
- Versions of this engine with a carburetor are especially problematic in their operation;
- At high mileage, the rear crankshaft oil seal often flows, and its replacement is expensive;
- Old or low-quality antifreeze greatly reduces the life of the pump and thermostat.
