yes, if the tensioner is bad it will make a noise at idle, but when you rev it up the chain will get tighter and the noise will go away.
the answer is yes. since the tensioner is hydraulic and require oil supplied from the oil pump to add pressure to the sleeve/guide.
if your timing belt jumped one tooth or timing belt was installed incorrectly you will be out of sync also a defective timing belt tensioner will cause sync problems
check your crank sensor. also check your timing chain tensioner. also your fireing box could have have a short. check your grounds on the complete bike if a ground is bad it will cause all sorts of problems. good luck
Sometimes the Timing belt tensioner will cause a tap or click until the engine is warm.
Depending on what is driven by the timing belt, it may be a few things. Usually the tensioner or water pump, but it could also be a glazed belt or even the cover rubbing on the belt
a common mistake when the timing belt is replace is to over tighten the timing belt tensioner. The tensioner has preset marks. One is a line, the other is a "c" shaped pointer. When setting the tensioner with the allen key, the "c" shaped pointer should be adjusted until the line is within the "c". This is the proper tension for the belt. If the tensioner was set properly the belt will not walk off the cam gears. Some of the zetecs have the tendency to run near the edge, not truly in the center. This is normal. As mentioned, the important part is to make sure the tensioner is set correctly. Over tightening the tensioner will cause the belt to walk off the cam gears
Failing bearings and spring loadings of the tensioner assembly can cause noise and belt tracking. However, timing and other mechanical issues can also cause ticking and clicking noises. The tensioner and idler pullies in addition to the belts are not considered a costly repair for this application. It is advisable to have the condition verified by a professional before replacing perfectly functional parts. However, belts are routing wear items and should be replaced at appropriate intervals.
Never had a predator cause of its kingness.
Check the tensioner on that belt it has to be adjusted properly too tight or loose can cause noise or premature failure.
Timing chain noise is most commonly coming from a loose chain. The tensioner could be loose or broken or the chain could be stretched. If the chain slips or breaks before you fix it, then not only will the engine stop running but you could cause serious damage.
Check the belts. If they are slipping they can cause this smell. Also if the timing belt tensioner is failing...it may be causing the belt to burn. Have this checked to prevent a major breakdown. If you have never replaced the timing belt. Just do it. Cheap insurance.
MOST LIKELY IT NEEDS TO BE TENSIONED PROPERLY OR, THE TENSIONER IS FAULTY.ALSO OVER TIME THE BELTS STRECHES AND NEEDS REPLACEMENT.
