On 944s/968s the tensioner pads and cam chains ARE wear items. I don't understand why the 928 would be any different?
Strange that no one has gone out and made bottom pads.

Thanks for the pics dan...
So the oil tube is backordered...
That sucks... I am pretty much at the point of pulling the tensioners off... but maybe I should wait until you say that you got yours to avoid a long wait....
Maybe the tensioners put more tension on the chain for 944/968???
I am pretty sure I need to replace Lifters tensioners check valves of all three...

You'd keep the old tensioner - at least the partly updated 86 one.
A = update for 86, valve plate designed like a piston
Seems to me all thats required is a bit of steel, slotted on the sides for the S4 guide to slide on, a hole in the center for the piston, and drilled/tapped for two screws.
What's the bottom one look like?

Why the 928S4 doesn't eat up chains like the 944S/S2/968 is a mystery.

Unless the actual tensioner is bad, the springs in the older style wear out. As my tensioner did, better safe than have teeth break, chain, etc, and destroy your head!

Well my old style tensioner spring tension feels very week so maybe it's time for replacement. My parts guy at Engine Builders Supply hunted around and called places. The other part numbers he came up with turned out to either be nothing or the wrong part. So looks like I'll need new tensioners and oil tubes. Hope they are in stock. Bottom pads look pretty good, hardly any wear but the tops are a little deep for my comfort level.
