Arrrrrrrg!!!!!

I’m in the process of adjusting the valves on my sc... AND LOSING MY MIND!

The first time I did the procedure it took almost all day and I was a little conservative, adjusting everything a little on the loose side. When I was done the car ran fine but the engine didn’t have as much power.

So like a crazy person I decided to do it again. This time I adjusted everything tighter against the feeler gauge. Now that everything is snug the engine does have more power. Amazing how that works???

The problem is that I’m still getting a loud tapping from one valve. I’m fairly sure its coming from the drivers side on the top which is good because I don’t have to drain the oil to remove the valve cover and fiddle with it.

But I’m confused about how to proceed though.

If the valve is very snug against the gauge already why is it tapping so loudly? Is it safe to adjust a valve a little tighter to quiet it down?

Some details:
The engine has 140,000 miles on it, has never had any work done to it and generally runs very well. Before I adjusted the valves there was a slight tapping but not as loud as the tapping I’m getting now. It sounds like only one valve is making the noise. The last time it had an adjustment a Porsche mechanic did it and told me there was one valve that he had a little trouble with but didn’t want to over tighten so he said I might hear a little tapping which I did but it wasn’t bad enough to be annoying.

So, can I tighten further then snug against the feeler gauge?
