    Can anyone tell me what the valve lash should be on a typical air cooled VW 1915cc should be? About all I know is that it has an aftermarket cam in it. Are they typically a hydraulic or solid lifter?

    I'm a total noob to the VW engines....

    They are steel....

    According to the info that I found on the other site, I should set them to a "loose zero" when cold... does that sound about right?

    Yup, you should still be able to rotate them but not feel any slop.

    That's the way I used to set mine, with a big cam they wouldn't idle for beans cold. Amazing transition when they'd warm up. Some of the later models did have hydraulics, but the guys I knew would sleeve them down for solids. They said it was stronger.....they told me this after I missed a shift and chunked out a lifter bore Things you learn. Never sleeved them (not cost effective)just learned to make sure I knew how to shift!

    Not to overstate the obvious but better loose than tight. German engineers are very very smart and if you stop and think about what is happening during the warm-up and running of the air-cooled vw motor it is amazing that they run as well as they do for as long as they do. The German engineers realized that they need the motor to expand equally as it warms up. If the jugs/retaining studs expand faster than the pushrods it is a very noisy motor, if the pushrods expand faster than the jugs, the valves wont seat and it does not run very well.

    All true except T1's came from the factory with aluminum push rods. This is why the stockers require .006-.008 clearance.......... With the steel push rods they expand at the same rate as the jugs, no real clearance needed. All you have to watch out for is case and head expansion.
