77 911s. Thoughts on these vs upgrade to hydraulic.

Thanks

Mechanical bad, hydraulic good.

I'd use the mechanical tensioners w/savers. The hydraulic versions have been known to fail, as well.

P.S. If you do a search on this topic you'll get all the opinions you wanted and more. it's been beaten to death.

Ok,

I didn't understand the original post. I thought you were talking about pure mechanical tensioners which some people use on race engines. They just have a fixed adjustment and no plunger to take shock loads. The early tensioners I wouldn't call mechanical just early. Early tensioners can work ok if you update the idler arms and use the savers. I'd overhaul or exchange for rebuilt and add the later (1980+) idler arms before I'd be happy with them.
