The last question needs to be answered. You don't discuss hydraulic lifters!!! I'm stuck. Tom wilsons book says two full turns after screw is seated on the valve. Any thoughts anyone?

I don't have any experience with adjusting hydraulic lifters on the Type IV engine, but this page here seems to have it covered pretty well: http://www.ratwell.com/technical/HydraulicLifters.html .

Yup the Ratwell page is the best resouce out there. Make sure that the lifters are fully pumped up before setting the adjustment. With a piston at TDC, you can't compress a pumped up lifter at all. If there is any squish, you need to keep trying to pump it up.

I had a hydraulic VW bug in the shop awhile ago and had to set all the valves with a small gap, drive with 'clacky' valves around the block, then adjust the lifters that had pumped up and keep repeating 4-5 times before all the valves were pumped and adjusted. After that they stayed pumped up and ran great.
