Can a bad belt tensioner cause misfire?
If the tensioner is worn, the belt will slip and then catch suddenly. Tensioners are more than just a spring. The belt will slip and catch, causing noise and vibration. This can cause a change in crankshaft speed that is severe enough to cause the engine management system to think that a misfire just occurred.
What kind of engine damage can be caused by a collapsed timing belt tensioner?
When the tensioner or tensioner pulley fails, the loss of tension can cause the belt and pulleys to make high-pitched rattling or chirping noises. If the pulley bearing completely fails, it can also cause a squealing or even a grinding noise. Symptom 2: Knocking or slapping.
What happens when you change the timing belt?
He changed the timing belt, drive belts, water pump, pulleys, tensioner and a few hoses, and everything seemed to go off without a hitch. After picking up the car, though, we noticed that the idle seemed much rougher than it had in the past.
Why does my car idle when out of time?
An engine slightly out of time can idle roughly since the spark is not in sync with the cylinders. Too much timing advance or retardation causes serious drivability problems. Many problems may upset timing. However, the most common is an overstretched timing belt or chain, or a bad tensioner after miles of operation.
Where can I get a timing belt tensioner?
Please contact BRECO flex Applications Engineering if you require any different material as we have the capability to custom manufacture tensioners to your specifications.
Can a timing belt go over two pulleys?
If the configuration of the t-belt is that it goes over two camshaft pulleys, well it is very easy to get that wrong. When it goes over only one cam shaft pulley it is smooth sailing, very difficult to get it wrong, but over two, many more ways to get it off a tooth or two. So that’s a possibility.
