i just realised that saving one for cam timing is probably not valid - i'ld do it with the belt that was already on then replace the belt - buggah.

Thats so funny, what the hell was he waiting for. does your neighbor not know your a 928 guru!

The mini rollers I've seen have been gummed up - basically fixed skids, instead of rollers.
I'm on the fence about whether to ditch the roller with my automatic tensioner. I kinda think it's a bandaid part, to compensate for the shortcomings of the factory tensioner.
BTW: I wonder why they only used the double roller from 87-90?

His theory is that the belt and pump are stresses lightly on the 16v engines. But, this pump did go the distance without a problem. Maybe a new pump is the way to go.

One came from my GTS. It was changed when I first bought the car but after 10k I went in again to change the cam gears (long story) and for the sake of $40 changed it again while I was in there.
The other was on my 87 and I changed everything just because I could and I was not 100% when everything had been done.
Steve are you coming on Saturday or to MF - we miss you.

Does it have the "Do It Yourself" manual transmission, or the superior "Fully Equipped by Porsche" Automatic Transmission?

I miss you guys too. Yes, I'm up for gtg Saturday and probably Marble Falls. I've been working on the '87 - steering rack, rack boots, ps hoses, lower ball joints, upper ball joint boots, tie rod ends, front tires, alignment, state inspection, RMB, window and sunroof switches repaired, new horns, new coolant reservoir. Motor mounts still look good. Next up - TB/WP.
