My 4108 runs perfectly, does not overheat, no smoke out the back. However, literally from one day to the other the oil
pressure dropped from 3,4 to 3 bar (same operating conditions, oil
level ok). This is still within the recomended operating range but what concerns me is the sudden drop from one day to the other. Is it a faulty gauge or is it a bigger problem (oil pump...) linked with the engine
?. If it is the engine
what are the probable causes?
Thank your for your advice,
