Yes, I don't understand chemistry, too close to magic, but I know caustic and ally don't work well. I'll need to look up the acid that doesn't eat ally and does eat steel when I get to the door tops, though. But that's another day.

Thanks! Is there a quick easy to decoke the combustion chamber? Mr muscle?

The valves have a lot of deposits. Is this normal. I took two out, and started to clean, but ran out of time. I think I'll replace the valve with deposits. If they aren't mad money, I might do both.

The crank feels really smooth, mirror like, but the photos don't reflect that, I think there's particles in the light oil I've sprayed on the journals. I hope to get a more experienced opinion on Tuesday. If it were me, I'd stick new shells on, and call it fine. But I'm of Yorkshire Scots descent, so have a tendency to exhibit tight fistedness. I know of this tendency, so try to compensate.

The rocker shaft has significant witness marks where the rockers were. I think I'll replace the rockers and the shaft anyway.

The pads on the rockers show wear. And I'm not convinced by the bushes.

The rocker gear is all a bit marginal, I think.

I also cleaned the cam followers and tappets. I think this one is worn:

I really don't know what's worn out, or what's good for another 50,000 miles.

Takes quite a while to do this. I also broke 2 oil control rings, which are tricky to remove. Piston 3 oil control ring was stuck into the groove.

I cleaned up the conrods and the pistons next:

Etcetera. I remembered to remove the pivot pilot bush. Using an old pinion and some scabby grease. I was surprised when it actually worked. I had to break up the bush to get the pinion to complete the removal.

More cleaning today. Crankshaft first.

Though it depends on the manifold used. If you could get a photo of the exhaust manifold where it bolts to the exhaust pipe, that would help.

yes, it should. Ask ACR about their stainless steel versions, Google them, with powerplus as a search term.
