• Searched forum but asking (still searching just have other things to do)
  
  I have this rebuilt shortblock and I don't have a HG or the ability to remove the headbolts from one of my "rebuildable" longblocks I have, however a headbolt from a Mechanical 1.6D fits in the block. so at least I know it should be 12mm but by the date can it be determined Hyd or mech?
  
  26 06 85 on front of block
  
  thanks

• they switched to hydraulic sort of midway through '86 I believe... my old '86 jetta had mech lifters
  
  I do like mech better than hyd.  I could fill that thing up with my heaviest of buddy's... tow a trailer... and the acceleration was still pretty much the same
  
  with the hyd... i feel the difference with just one normal sized friend.

• Hydrolic. Notice the second oil passage on the front compared to mine?

• Yeah looks like I thought faster than I could type, I meant to say that yeah it looks like a hyd block but figured I would post a picture just so people have  a visual reference and that even though my block has an early 85 date it still is a Hyd
