Hey all,
I haven't found the answer in the forum so here it goes ...
- 4 months ago I changed my belt & crank pulley as they were very worn, though still functional (intermittent noise from worn belt).
- My stilo 1.9jtd has an auto tensioner - new belt went on fine and new crank design came with proper screws so no worries on parts fitting.
- I could hear a slight clacking or tapping a few days later, especially at idle, vanished in 3rd gear. Since then have readjusted the crank pulley to ensure it's perfectly aligned as it should be.
- The noise got progressively worse over 2/3 months and I can no longer ignore it as people in the streets duck for cover when i'm coming. The tapping or clacking noise is really really loud.
- Today I removed the aux belt and ran engine. No tapping. I suspected tensioner pulley as it wobbles a fair bit under operation (probably normal? - circa 15mm) and dismantled it to take a look - a bit worn on the inside from occasional friction but otherwise fine, put it back on with belt, spins pretty good by hand. Noise remained. Sounds like metal on metal to me.
Any ideas ? Tomorrow i'll try sticking a screwdriver and plastic bottle to each pulley with engine running to get a megaphone effect and maybe find it that way. I have other electrical issues which are nuts but I think they really are just bad connectors, earth wire or dirty fuses.
Thanks in advance !
