This picture is after the holes were drilled but before tapping them for the M8x1.25 bolts. In my previous setup I was aiming for accuracy but could not have drilled the holes through or the bit would hit my vise jaw.

In the pic above you'll see I flipped the part around and set it on a sacrificial plastic spacer. You'll see this plastic again later, when I use it to create the special Porsche tools used to hold the cams in place for timing purposes but for now you're looking at a scrap of plastic. All I had to do was unlock the table of my drill press and relocate the center of the holes I started, then change up to the drill I would us to pilot the tapped holes and blow them through.

Next I tapped the holes M8x1.25, and then verified that they fit the cams (they did). Then I eyeballed the stuff that would need to be removed, marked it with a sharpie pen and took a hack saw to remove the excess metal. Then I grabbed the file and made it presentable at 5'.

I learned a TON from my uncle many, many years ago about taking the time to do things right and making what you couldn't buy. Now, where I used my file to round off sharp edges he would have gone to town and probably would have applied a black crackle finish and some sort of data plate. One of these days I'm going to be as cool as my uncle.

The hole used to sock the tool down in position doesn't have to be a close tolerance hole. It just has to be a nice clearance hole. So I blew it through with a 21/64" bit and then tried to install it.

It works.

Now my tool looks a bit light duty compared to tools you might spend a ton of money on. I would have felt warmer inside had I used 1/4" thick extrusion, but then I'd have had more work to do. And truth be told the cams don't want to jump off the head when you remove the cover. They just want to be held. This tool does that. In fact when I got to the part where I pulled the cams off I had to loosen this tool to let go of the non driven ends of the cams.

I was not horrified with what I found when the cover came off. Yet.

The worst thing I see is the cam journal (which is the inside of the cam cover) in the middle left of the pic. It looks worse in the image than it does in real life. You cannot feel any of the marks you see.

Some more exposure:

Here's that ugly cam journal inside the cam cover. Again, you can't feel any of this that you see. Looks to me like some debris has been pumped through here.

Where I stopped for the evening:

I got all the cam lifters out and I have my request in for an egg carton which I'll get after brunch tomorrow. I loosened all the hardware I could find on cam lifter carrier, but it didn't jump into my hands. I was way tired so called it quits for the day. I cleaned up my tools and the garage.
