Question

All of the following are common causes of low engine compression except for

A. too much oil
B. defective valves.
C. weak piston rings.
D. bent pushrods

Answer 1

B

Step-by-step explanation:

Over filling of oil on an engine will not cause loss of compression. The crankshaft splashes it inside the engine and will come out the dip stick tube and breather on valve cover and it may splash up to the bottom of the pistons and force oil to the top through the rings
