Thanks Adam. Tensioner is between 5-6mm so within spec.
I replaced absolutely everything six years ago including all the gears and wp.
I seem to recall back then the theory was change the belt every five years regardless of mileage...quite some paranoia about it actually. Has the general consensus changed?

No change in the consensus. If you have it apart you may as well change the belt, if not I wouldn't worry much for this summer.

Just did this on my GTS. I replaced the actuator and tensioner roller after 10 years and about 50000 km (with the water pump). None of the parts needed replacement. No leaks and the bearings in the LASO pump and tensioner roller felt like new. No rattling noises, nothing. They would have lasted another 50000 km with no issues. But why risk a perfectly running GTS engine with GT cams and sharktuning?

BTW my PorKensioner is from the first series (gold plated) and is just fine. The biggest improvement on the newest generation is the fact, that it is easier now to get the TB over the cam gears (good job Ken)!
All other improvments were implemented in order to prevent installation mistakes by mechanics or wannabe mechanics. If you know how to use Loctite and a torque wrench, there is no need to change the bracket.
Left mine in place, all good for another 10 years.

Not really, but it was a bit conservative to begin with (for good reason).

The belts do much better in a cooler climate (upper Great Lakes is one of those). Less so in "hot and dry", say Phoenix and the Middle East.

I did my TB at maybe 15k miles and 7 years. Belt was fine. I could have put it back on without worry. But since the cost of the belt itself is minimal, I put a new one on.
On a similar note, I did the belts on my 944 at 20k miles and...
13 years.

Those belts looked perfectly fine too.

After looking at the belt I would be inclined to just leave it but since it has been over six years and I have another belt, and the covers are off I might as well change it.
thanks again

I didn't know Gates made de-tensioners for the shark.
