Hi

I have had my st170 for a bit and there are a few niggles with it the one that I am aiming my attention at is the noisey engine it sounds like the tappets are shot....sounds like my old xr3i from years ago !

I kniow these are supposed to be slightly noisier than other zetecs but my mates one is silent mine has done 80,000 its just hasd an oil change which I thought would of cured it but hasnt !

any ideas if the tappets or lifters tend to wear or what it could be ?? been hearing feeww people mention inklet ? but would this sound as mechanical as tappets ??

scratching my head and its annoying me !!

Also it seems a bit hesitant when putting foot down so could this be linked atall ???

help please would be great !

cheers
Ryan

 

This is usually either the idler pulley on its way out, or the engine has 10w40 in it instead of 5w30
