I didn't check out my valve adjustment screws last time I adjusted the valves and they seem a bit noisy to me.. (BTW how noisy should they be??) so I was going to pickup a new set of the adjuster screws to have on hand in case mine look worn the next time I go down there. Wondering if anyone has an opinion on these ones for my 1.7 from Pelican:

The screws shown at the top of the picture are aftermarket "swivel foot" adjusters. The lower ones in the same picture are also aftermarket, and have a larger than stock contact pad. One of the things stock adjusters do is cause the valve to rotate in the guide, just a little with every contact. Swivel feet and 911 adjusters don't do that. It's a designed in feature that you need to consider when doing this mod. BTW, the swivel foot in the picture is, IMO, crap. I've seen lots of failures over the years, and it's been a long time since I saw one in an engine. They were the hot "thing" in the 70s. Difficult to get a feeler gauge in there, too, especially in a 914.

Thanks Captin! I think your correct on all your points. The adjusters already in here are probably aftermarket from a former owner. I think they put a cam in for carbs as well but I'm not going to check that out. I think I'm gonna send these adjusters back to AutoAtlanta and get stock ones....from.....Pelican Parts? The Porsche Dealer?
