How does oil pressure affect a timing chain tensioner?
Timing chain tensioners. The oil pressure of the engine hydraulically operates most timing chain tensioners. When the engine starts, oil pressure allows the tensioner to push the guide against the chain and remove slack. Turning off the engine causes the oil pressure to return to zero.
Can a sprocket be replaced on a timing chain?
Only replacing the worn chain and sprocket will restore proper mechanical timing. The oil pressure of the engine hydraulically operates most timing chain tensioners. When the engine starts, oil pressure allows the tensioner to push the guide against the chain and remove slack. Turning off the engine causes the oil pressure to return to zero.
How does an anti drain back valve work on a timing chain tensioner?
Timing chain tensioners. An anti drain-back valve, in a quality oil filter, helps keep oil in the passages, leading to the hydraulic tensioner. It does this by blocking the return of oil through the filter, to the oil pan. Without oil in the passages, it takes longer for the oil pump to pressurize the tensioner.
Why does the timing chain rattle when the engine is shut down?
The timing chain tensioner may bleed off oil pressure after the engine is shut down. This can cause a rattling noise when the engine is started cold and a revised timing chain tensioner and guide are available to correct this issue. timing chain rattling noise coming from passenger side of engine.

What happens when there is no oil in the tensioner?
With no oil pressure, gravity pushes the oil in the upper part of the engine, back to the oil pan. This leaves the passages, where the oil flows, empty and increases the time it takes to return oil to the tensioner on startup.

How does the oil drain from a chain tensioner?
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.
Why is my chain tensioner on my Harley not working?
An unfamiliar sporadic noise caused me to change my oil. Upon starting, no oil pressure at all. Shut down immediately. Removed oil filter and crammed the TC88 over. No oil coming out. I only did this because I have an H-D oil cooler and wanted to rule it out.
How does the timing chain tensioner work on a Holden?
The engines have three timing chains and three timing chain tensioners. These tensioners are hydraulically actuated via pressurized oil from the engines lubrication system. This keeps the chain slack to a minimum and allows for automatic adjustment. Each tensioner also has an oil jet that sprays oil onto the chains while the engine is running.

When to use thinner or thinner chain tensioner?
Exactly . . . thinner = less pressure . . . getting into the nooks and crannies and lubricating is one thing but creating max pressure is usually when the oil is coldest. Viscosity is greater . . .
Where is the oil in the timing chain?
This reservoir of oil is contained by the rubber covered metal gaskets that seals the tensioners to the block or heads. As this engine was dismantled and the timing chain tensioners removed, it was found that one the tensioners had not had the metal gasket fitted when it was being assembled.
