Hey guys,
I was adjusting my valves and noticed one of them was way off (see pic). (IMG:style_emoticons/default/WTF.gif) I screwed in the adjustment screw to take up the slack for this picture so you could see how much it took to tighten the valve. When i purchased this car it seemed to be running fine especially after a tune-up just a little noisy, this is the first time I've tried to adjust the valves and i figured this would be a good time as any sense I was already removing the tin to clean out the debris. Please break it to me gently (IMG:style_emoticons/default/icon8.gif) do I have major problem?

There is s trick to adjusting hydraulic lifters that have air in them (not pumped up).
They all have an internal spring that pushes the piston the push rod sits on out toward the rocker. This spring does not have much tension so the piston is easily pushed in as you try to adjust out the clearance. If you loosen the adjuster until you know you have a gap and then gently turn the adjuster while twisting the push rod with you finger tips, you can feel the push rod tighten up slightly as you take out all the clearance and start pushing against the spring. You probably need to tighten and loosen a couple times to get the feel for it. Once you can get zero clearance then you can turn in 2 turns to set them correctly. I learned this from a Chevy mechanic and it works quite well. Twisting the push rods on a 914 is a bit tough because of the space but what isn't.

Good Luck

Jim
