Disadvantages, breakdowns and problems of the internal combustion engine AR67301
On the internal combustion engines of the first years, the cams of the exhaust camshaft wore out rather quickly
Another weak point of this power unit is the valve guides.
Also on the forums, the unreliable hydraulic timing belt tensioner is often scolded.
A lot of trouble here is caused by constant leaks, and especially on cylinder head gaskets
The remaining problems are related to air leaks in the intake and engine overheating.
