Question 1 of 30👑 VIP
A customer brings in a 26-foot twin-engine fiberglass cruiser complaining that the port engine starter cranks but the engine will not fire. You confirm there is spark and adequate fuel pressure. A compression test reveals cylinder 1: 155 psi, cylinder 2: 152 psi, cylinder 3: 80 psi, cylinder 4: 78 psi. You squirt a small amount of oil into cylinders 3 and 4 and repeat the test — compression rises to 130 psi on both. What is the most likely cause?
