Why does my timing chain make a tapping noise?

Check for a break in the gasket of the tensioner, between it and where it bolts on, that will allow oil pressure to bleed out and not give full pressure to the tensioner. Thing is the car only makes the tapping noise when the car is at full operating temp which i would assume when the oil is at its thinnest.

Can a bad timing chain cause an engine to misfire?

Engine misfires. The timing chain method is more common with consumer vehicles and high performance engines. Over a period of time, the timing chain can stretch, which can cause the chain to skip a gear on the cam or crank shaft. This results in the engine’s timing to fall out of calibration and often results in a misfire.

How does a timing chain tensioner work when not running?

The tensioners are kept tight with oil pressure when the engine is running. The oil drains back when not running, but some tension remains on the chains from the spring inside the tensioner until it starts and is pressurized. I have gotten almost everything off the front of the motor.

Can a timing chain be replaced on a pushrod car?

In old-style pushrod engines, replacing the timing chain is a fairly easy task. No such luck if you have a modern front-wheel drive car with a transversely-mounted engine, as the space in the engine compartment could be very tight.

Improper flex or bending of chain, tight joints. Chain is not installed correctly. Inspect the installation and correct as necessary. Contamination from metal dust or dirt because of improper lubrication. Remove the chain, wash it thoroughly, and provide proper lubrication.

What causes the pin to come out on a chain?

Operating a chain at high load without proper lubrication can create friction between the pin and bushing, causing the pin to rotate. In this condition, the pin may come out, leading to chain breakage. Replace with new chain immediately.
