How do timing chains work?
A timing chain synchronizes the rotation of the crankshaft and camshaft(s) ensuring proper timing and allows the engine’s valves to open and close during each cylinder’s firing. The chain is located inside of the engine and needs to be lubricated by the oil in the engine, making oil maintenance important as well.
Where is the timing chain in an engine?
Every internal combustion engine has a timing chain or belt. It’s in the front of the engine attached to a set of gears and pulleys that power components like the crankshaft and camshaft. A properly tensioned chain is critical to maintaining the timing between the pistons and the valves.
Why do I need a tensioned timing chain?
A properly tensioned chain is critical to maintaining the timing between the pistons and the valves. When timing chains loosen it leads to engine rattles, issues with misfiring, problems accelerating and – eventually – bent valves or rods and catastrophic engine failure.
How do you change the timing chain on a Jaguar?
First, take out the right hand bank primary chain. Then, detach the variable valve timing (VVT) solenoid and the bush carrier. Then, lodge the camshaft locking tool to the left hand bank camshaft and align the shafts as required. Next, unfasten the exhaust camshaft sprocket bolt and the intake VVT unit bolt.
What happens when the timing chain loosens on a Nissan?
When timing chains loosen it leads to engine rattles, issues with misfiring, problems accelerating and – eventually – bent valves or rods and catastrophic engine failure.

Why is my timing chain cracking on my Jaguar?
This could be due to a cracked timing chain tensioner and guide. The best way out is to inspect the plastic inside the valve covers for any crack. If so, replace the chains. Additionally, confirm if the noise is coming from the top front of the engine to repair, as needed.
How to replace the timing chain on a Jaguar XJ8?
How to replace the primary timing chain on a Jaguar XJ8? First, take out the right hand bank primary chain. Then, detach the variable valve timing (VVT) solenoid and the bush carrier. Then, lodge the camshaft locking tool to the left hand bank camshaft and align the shafts as required.
What are the symptoms of a bad timing chain?
Symptoms of a Bad or Failing Timing Chain. 1 1. Engine misfires or runs poorly. There are two ways to achieve valve timing in a combustion engine. The first is the two-gear method, which includes 2 2. Metal shavings found in the oil. 3 3. Engine won’t start or fails. 4 4. Check Engine Light is on. 5 5. Engine rattles while idling.
