Timing Belt & Timing Chain Problems: Warning Signs

The timing belt or chain synchronizes the rotation of the crankshaft and camshaft. If it slips or breaks, valves and pistons can collide.

Warning signs include a ticking noise from the engine, difficulty starting, engine misfires, or oil leaking from the timing cover.

Many manufacturers specify a replacement interval for timing belts. If you don't know when yours was last replaced, it's worth finding out.
