I have never wrenched on anything before but I am mechanically inclined and I found the valve adjustment to be a breeze with Kerry's instructional video.

I saved this video so I can do my valves myself.  I watched it and when he said he was going to take the test shim out and put the 2.60 shim back in before he went to the shop to get the 2.50 he needed, he then cut tape and explained why he needed to use Permatex on his valve cover gasket the last time he adjusted his valves.  He then presumedly went to get the 2.50 shim.  All that obviously caused him to forget to take the test shim out so he put the 2.50 on top of it, put it all back together, and had to do it all over again.  He obviously didn't check his clearance after putting the 2.50 in or he wouldn't be able to fit any size feeler gauge in there!

I thought it was very self revealing of him to leave that gaffe in.  He easily could have edited it out!  All in all, great job, Kerry! 

Oh yeah, and for 33 bucks there has to be a better valve bucket depression tool than that!  It was pure comedy watching him try to get it to hold the buckets down!
