Initial start-up after overhaul or major repair

SOHC engines / Initial start-up after overhaul or major repair

1 Refer to Chapter 2, Part A, but note that when the engine is first started, a metallic tapping noise may be heard. This is due to the timing chain tensioner plunger assembly taking time to pressurise with oil, resulting in a temporarily slack chain. The noise should stop after a short time, once oil pressure has built up.
