When to replace the timing chain tensioner on a V8?
Replacing the timing chain tensioner is highly recommended to increase the life of the V8’s, in particular the integrity of the timing chain guide rails. When the tensioner wears or becomes gummed up with old oil, the timing chain can slap around destroying the guide rails.
How to replace a chain tensioner chain rail?
Remove the 10mm bolts at the top of the timing chain guide rails (both front and rear) and replace the guides with new ones. You get to the 10mm bolts through the 2 large, round ports on the side of the housing. There is a pin at the bottom to hold the lower side of each guide rail… be sure the new rail sits down on the pin.
What happens to a timing chain when oil wears out?
When the tensioner wears or becomes gummed up with old oil, the timing chain can slap around destroying the guide rails. The tensioner is a hydraulic device rather than just a sprung piston – the action of the tensioner relies on the condition of the piston and cylinder.

What happens if a timing chain tensioner fails?
Failing of a timing chain tensioner can occur slowly and if you do not catch it in time the slapping chain and lead to a number of engine related problems – some catastrophic. In this video I will show you how to test a tensioner on the bench by comparing one that has failed to a brand new one.
When to replace the timing chain on your vehicle?
But there are differences. For one, timing belts need to be replaced periodically in accordance with the vehicle manufacturer’s maintenance schedule. Timing chains do not require routine replacement and should last the life of the vehicle. There are also differences in design.

Where is the tensioner on the M60 timing chain?
The timing chain on the M60, M62 and M62TU is tensioned by a single tensioner that acts on guide rails as shown above (the tensioner is part # 20). When I got the new one out of the box it looked like this: Yes, the piston is pushed right inside the cylinder…..so I gave it a squash……. ….and the piston came flying out!
How do you replace the tensioner on a Porsche?
Use the Porsche timing tool or an 8mm Allen wrench to lock the crank pulley to the block. Lock the crankshaft (and, when required, the camshafts) in position. It is crucial to lock the crankshaft to prevent the timing chain from jumping when the tensioner is removed.
When is it time to change timing chain?
A timing chain is a major component used to keep an engine’s timing in sync, and replacing it is often an essential part of automobile maintenance. Timing chains typically last longer than timing belts and are preferred by some automakers for their durability. Most experts recommend replacing a timing chain every 100,000 miles or so.
How long does it take to change timing chain?

What should I replace my timing chain tensioner with?
When replacing a timing chain tensioner, replace the whole timing chain set, which includes all of the chains, the gear set, the tensioner (s), and the guides. An engine may have multiple timing chains; replacing all of the chains and their related components is recommend if one chain requires replacement.
When the tensioner wears or becomes gummed up with old oil, the timing chain can slap around destroying the guide rails. The tensioner is a hydraulic device rather than just a sprung piston – the action of the tensioner relies on the condition of the piston and cylinder.
Where do the timing chains meet on a Ford Coyote?
Both timing chains meet at the crank sprocket as shown. The left-bank (driver) chain is installed first, then the right (passenger). Timing marks on the links and gears allow timing adjustment during chain installation.
