    Think I'll just stick with what the manual recommended in terms of settings. Especially for a relative beginner like me!

    It's always good to have plenty of info though, I did read through a few different threads on setting tappets and this one seemed easiest to understand.

    Well, I didn't grab a beer but i read the thread. Very interesting stuff and certainly can't disregard the posts by Glenn & Raby - these guys know what they're talking about with decades of experience...

    However, they are talking about custom aircooled engines with lots of 'expensive' bits and hand built to precise tolerances. OEM VW engines were a bit more 'slap n dash', mass produced.... still, very interesting!

    I think that VW have built more engines than any US engine builder.

    The change from .004" to .006" was because owners were burning valves. If they do open up when warm, well that's what they have been designed to do and the .006" is what has been compensated for.

    hey Tom,

    Many thanks for that video link. Like so many people, I tend to take a healthy and functioning rear end, for granted. But when it lets you down, you really know about it.
    The video, reminded me of my first sex education video, a couple of years ago. It was such an eye-opener!
    I am so impressed now, with my new found knowledge, that just like I did after the sex education video, I want to go out and practice my new found knowledge. I just hope, that I am a little more successful, that I was after the sex education video.
    Anyhow…….This is not to brag about my delusions of adequacy….I just wanted to say… Thanks!…….And if you have any more videos like that, please post them (or brown paper bag to my office)
    warm regards
    JD in Adelaide:cool:

    Great stuff Tom!! Simple, yes, but it gets the message across in terms that (almost) everyone could understand.
    Cheers, Mark

    The only thing I could add is maybe adjust as described, drive for a few days and check again. The better they are adjusted the better the engine goes!

    Great thread!

    I am looking at my distributor, it has the bulb on the side, but it is mounted 90 degrees anti to the one in the photos! What does this mean!!? Do I need to adapt the steps?

    The notch still seems to put cylinder one at TDC but I am not experienced enough to be sure.

    Thanks!

    Hi guys,
    Long time lurker but first time poster here. I'm actually Markus' (KombiMadness) son, who I think the original post was intended for, and I've just bought my first Kombi, a '75 Microbus 1800, about a month ago and I've just decided to try to adjust the tappets. Didn't get very far until I hit a few road blocks so I've got a few questions.
    Do I use the timing scale and the notch in the pulley OR the rotor arm and the notch in the distributor body? They don't line up at the same time so I'm a bit confused.
    I've tried both methods and still am stuck because the feeler gauge just won't slip through. So I loosened the adjustment screw off and it still didn't fit. A little more and it still wouldn't fit through and that's when I knew something was wrong because I'd backed the screw off a solid 3-4 turns, the rocker arm wobbled when I moved it but the gauge would not fit through!?!
    Am I doing something completely wrong?
    I've followed this guide step by step and also "Valve Adjustment for Smarties" by Schmoburger and still I'm lost...
    Any help would be greatly appreciated!
    Jaye
