Can low oil cause rattling?
Reason, Low Engine Oil Level: If the oil level gets too low, you can have a situation, where the oil pump sucks air into it; and the air gets pumped through the engine along with whatever oil is remaining. As a result, This can cause a rattling or ticking noise from within the engine.

What does a timing chain sound like when it is bad?

Does a timing belt make noise before it breaks?
When the timing belt wears out, it can cause a ticking or clicking sound to emanate from the engine. … There is a tensioner that keeps the belt taut, and that tensioner is pressurized by the engine oil. If the tensioner has no oil pressure, the belt will become loose and possibly disengage from the pulleys and/or break.
