I can imagine how easier it is to work on the engine with your stand!!
This could be my next project.

Excellent thread Mike.
The picture of the exhaust valve is interesting. The pitting on that looks really deep. I had my top-end rebuilt for the dreaded SAI, and had new exhaust valves and guides put in. I still have the valves that came out and they looked smoother than in your pics.

Leakdown...results??? Did you isolate where the leakdown occurred? Intake, Exhaust, Rings? Any idea? Great series of pix. Setting a standard there if you ask me.

BTW I was measuring wrong. The picture is really small in the manuals, I measured the slop at the top of the valve stem, not the bottom. I rejigged and measured 0.90mm movement at the bottom. Its still not as per the manuals since I am using my old valve and I did not remove the seal. After my machinist takes them all apart in the next few days and I get new valves (if I n eed them) then I will remeasure.
Posting a picture of what your found would be great.
Cheers,
Mike
