Hey guys. Thanks for the inputs. I notice no change in the RPMs, it pretty much stays the same. If anything it seems like it may drop off a little. I'm probably going to try the compression check. I need to change valve seals anyway, so between both jobs it'll give me a reason to pick up some tools.
I've priced a clutch setup, and it doesn't seem too awfully bad. Any ideas on what clutch dia. size/spline count I'd have? I can get plenty of assistance, so I could probably do it myself.
I was worried that the truck might start showing some signs of old age when I started this commute. It might be just about time to pull the cover off the Z and do a little work on the truck.
Any more comments are welcome, and thanks again.
