What does it mean when a timing chain stretches?
Timing chains don’t actually stretch. Timing chain stretch is not actually the ‘stretching’ of the chain, it’s an elongation of the timing chain caused by wear in the chains components.
How do you reload timing chain tensioner extended?
You have to “reload” this Tensioner just like the one on the Camshaft chain, but no special tools. Just rotate plunger 90 degrees to compress, then back to original 12 o’clock position and insert paper clip through hole in plunger body and into hose in Tensioner plunger.
Can a bad oil change cause a timing chain problem?
When new, the tensioner and guides work well to keep chain noise to a minimum. But if you don’t change your oil according to the carmakers schedule or use the wrong type or viscosity motor oil, timing chain problems can develop, such as timing chain stretch and even metal breakdown.
Do You need A tensioner on an overhead camshaft?
In older engine designs without an overhead camshaft, the timing chain is short and doesn’t require a tensioner (see image). However, as carmakers began using overhead cam designs they were forced to incorporate much longer timing chains to span the distance between the crankshaft sprocket and the camshaft sprockets.

Why is my timing chain making a noise?
If the engine is equipped with a hydraulic timing chain tensioner, the noise may disappear or lessen as the engine oil warms up and the tensioner removes some of the slack. If the timing chain wear is great enough so the tensioner can no longer compensate for the slack, the noise may continue even after warming up.
