Hi,
I saw on Facebook that Tony Lindsey-Dean got a bunch of timing chain tensio=
ners hard chromed for wear resistance.
Seems like a good idea and (probably) what the factory did.
I've been a convert to cryogenic treatment for wear resistance on cams and =
tappets and=C2=A0 highly recommend the effort. But I'm curios to see if any=
one on this list has tried cryo for the timing chain tensioner...=20
Discuss.
Regards,Bob Lang
