Well, I'm not Vaughan, but the fact of the matter is, I could probably replace
a valve in my GT6 in about 4 hours, if all went well, and if I had the
necessary parts on hand. I pulled the head on the GT6 in 1 1/2 hours, and
I figure an hour to replace the valve and another 1 1/2 hours to put the
head back.
The overall task is taking several days, though, because I had to order the
valve and a gasket set. If I had had them on hand, I could have done the whole
job last Saturday morning!
Since this was the second time I had pulled the head, it was much simpler
this time. I knew what had to be done and how it all hooked together. Also,
nothing was seized or stuck, and the head came loose with some rocking.
I'm also getting really good at disassembling and reassembling the rear
suspension. I figure I could replace the transverse leaf spring on my GT6
in about an hour.
Wrenchingly yours,
Larry
