Hi Volks, Here we go again; I'm in the throes of another "Vanagon Experience". Headlight adjusters; slave cylinder... speedometer, headlight switch, etc. Up to now I thought I would miss out on starting my own "Hydraulic Lifter" thread. But apparently that is not the case.... I tried adjusting the valves on my WBX this weekend. First time I have done hydraulics; though I have been doing solids for many years now. I turned the cold engine to TDC#1, and backed off the valves on #1 cylinder until they were sloppy loose. Then I tightened them up to the point of contact, and went two full turns beyond that, and tightened down the lock nut. Then I did a compression test, and got NOTHING. Zero. Zilch. Nada. Tried again at 1.5 turns, same result. So then asked my daughter to turn the key while I watched the rockers. Everything is moving correctly, so I backed off to the point of contact, and the compression came back up to normal. I had this experience on #1 and #4 cylinder. Didn't try #2 or #3; I want to find out what's going on before I mess with it further. Now I am wondering if I have a collapsed lifter, or does this engine have solids in it? Is there a way to tell without pulling it apart? It doesn't clatter like it would with a bad lifter. I know it SHOULD have hydraulics in it, but then again it's already a weird setup with a 1.9L block using 2.1 FI and cooling and a 1.9 exhaust welded together from tip to tail. Solid lifters wouldn't really surprise me. I drove it about 20 miles today, and it ran fine the whole time. If they are solids, I guess I need to readjust at .006 clearance. Sigh.
