回油阀损坏或失灵
为保持主油道有正常油压，此处设有回油阀。若回油阀弹簧疲劳软化或调整不当，阀座与钢珠的配合面磨损或被脏物卡住而关闭不严时，回油量便明显地增加，主油道的油压也随之下降。应检修回油阀，将其启压力调整在0.28-0.32Mpa之间。
机油散热器或管路漏油
漏油既脏污发动机，又会使油压下降。管路若被脏物堵塞，也会因阻力增大而使油的流量减少，导致油压下降。应取出散热器，焊补或更换散热器，并经压力试验后方可使用；清除管路脏物。
压力表失灵或油管堵塞
若压力表失灵，或由主油道至压力表的油管因污垢积聚而流通不畅时，机油压力便明显地下降。可在发动机低速空转时，徐徐地松开油管接头，根据涌出油流的情况确定故障部位，然后通洗油管或更换压力表。
