2010 Toyota Corolla Question: On first startup in the morning, the engine makes a clicking noise.
Answer #1pushrod April 18, 2013, 01:03Master
Timing chain noise until tensioner extends, to tighten the chain, from oil pressure. Not a real problem as long as it dont get worse! Try some Lucus oil stablizer with next oil change. Good stuff! Post results later, would like to hear that "clicking noise" is gone.
