Question about 2010 Mazda 2 1.25i
The car has run 55 kKm when it become noisy and the noise came from the chain gear. I disassambled and discoverd nothing but tensiner's chanel blocked up by small peace of silicon. I cleaned it and I am know ready to assamble it again. The question if this could had been the only problem?
Have you got chain at manufacture's specification for free play , piece of silicone is i presume a piece of rubber ,has this come away from any oil seals? gasket from rocker cover ? or anything that looks as if it has a piece missing,i'd check these before reassembly just for piece of mind

Replacing the timing chain is done around 100,000 miles, but can last as long as 200,000.
Sounds like something may be on its way out, and a rattle does indicate a chain. Not all oil pumps use chains...many use gears to spin the oil.
Most people know when it needs replacement when they are calling for a tow truck.
It could be your water pump as well. It is hard to tell where the sound comes from sometimes. A stethescope may help pin-point the sound to the part.

The keyway and or the dot on the crank should be line at 12 oclock. You will see a point on the oil pump housing to go by. On the camshaft the pointer will be at 12 oclock also. Use the O on the camshaft to the top at mark. Be sure to look at the dist. roter to make sure that it is pointing at the #1 spark plug wire. I could get 180 out of time. If you do it right it should start up right away. then you can use a timing light to finish it.
