Duratec high RPM timing chain tensioner mod
Anybody heard of this issue/mod before?
http://www.dubaipetrolheads.com/index.php?topic=1213.0 Came across it while searching about the rattle coming from the front of my engine(hopefully a belt tensioner-not timing chain related!). Anyway-not that I'm revving above 7400(hopefully some day)but I wasn't aware of any duratec chain tensioner issues....

Re: Duratec high RPM timing chain tensioner mod
Big cams and big tension valve springs & high rpms make this a must do.

I guess if I take mine apart again I may have to look into this just as added safety.

Re: Duratec high RPM timing chain tensioner mod
Well it looks like you found my website, the tensioner mod is a must do on 2.3 engines being revved above 7500 or so, as the cam chain can back lash and break the teeth on the automatic tensioner. It is a very easy mod to do, I know the guy that supplies Caterham with theirs and he does it for about $20. I am putting one in my 2.0 as well, as it seems rude not to and I plan to rev to 8500 or so on the new engine.

Re: Duratec high RPM timing chain tensioner mod
How many have you guys seen break? Do you have directions on how to modify yourself, or a link to where it is on Raceline's site? Also, does anyone know the intended purpose of the rachet mechanism, and why is deleteing it better than it breaking?
