I think you should go a little easier with the "blue", apply with a stencil brush and just colour the surface.

You're absolutely right...I took that pic after I globbed it on. I used an acid brush to remove the excess before I inserted the valve.

After backtracking for nearly three months to modify my cam housings, I'm almost back to where I was.

But this gave me some time to make my own top dead center tool. Cost $20, worked perfect...



I also had time to fabricate my own digital degree wheel. The rotary encoder was $50 and another $20 for the aluminum "fixturing"...



Used the TDC tool to find calculated TDC...



Set the DC43X-102 cams at 4.6mm lift at overlap for the 1-2-3 side...



I was able to hit 4.58mm lift at overlap for the 4-5-6 side...



Onward...

Would you be willing to write up a DIY on how you made the tools? I'm sure I could figure it out but a guide is always nice.

This should be the definitive build guide for a Mg case engine.

Sure, happy to share! The digital degree wheel is still mounted to the engine so I can't show that right now, but here's how I made the TDC tool...

I bought a TDC tool from Amazon. It's got an internal thread of 3/8"-16 tpi...



Removed the "stock" screw and tacked it to an 8" length of 3/4" diameter DOM tubing. Nothing magical about this, it just happened to be in front of me at the hardware store. A schedule 40 steel pipe would have been cheaper...



On the other end, I tacked a washer and a 3/8" nut so I could snug the tool down. I drilled out the threads so the threaded rod could move freely...



Last is a 12" threaded rod with a slight chamfer at the piston end with a 3/8"-16 tpi nut welded on the other end. I had planned to use another 3/8" nut as a locknut, but I didn't need it. Plus, I forgot to buy one...



Overall, this contraption cost about $20. I could've made it for $15 if I was more frugal.

I'll post the degree wheel when I have a chance...

Nicely done! I tried to make this but failed to get the 3mm threaded shaft on the angle finder connected before I mangled the circuit board. I ended up with some scrap. I did have a nice magnet attachment to the crankshaft though, did you use a magnet?

Back to where I was three months ago...

Rockers installed, valve lash set...



Lower gasket installed...



Lower valve cover installed, modified for twin plug by Henry at Supertec...



Upper gasket installed...



This is my engine. There are many like it, but this one is mine.

Valve covers installed. Cerakoted "Barrett Bronze" by Shaun at Tru6...



Custom cam housing oil lines by Brad at 911rennen.com...







Long block basically done!

Updates will be slow in coming for a while. Onward...
