Couldn't resist popping the cam cover off for a look before the engine goes up to the guru.
At least it looks good up top :D

Crikey.

Yes, many Sperts down there it seems. I've also had thoughts about retyring in the Tamar Valley area. Beautiful spot to see out the final days, and plenty of Sperts for the enthusiasts.

So dropped the engine in at the Guru's cave up the coast...
Curiosity got the better of us and the decision was made to take the head off for a look :D
As suspected, wasps had used the open combustion chamber as a luxury apartment over the years.

Took considerable amount of time to actually wangle the head off.... corrosion around one stud meant lots of jiggling, wobbling and rocking before it finally came free.
It also revealed a laminated steel head gasket...so this baby has been rebuilt in a previous life :think:

So it seems the engine is in rather good condition, everything looks as new!
Cams, shims and buckets all great. Cam runs directly in the alloy carriages (no bearing/bush) and they to look spotless, not a scratch to be seen. Pistons are clean and once again have no scoring etc. at all and the ring gap looks perfect, although the rings are currently stuck in the grooves on the piston left open to the elements. They should free up without too much trouble though :D
As soon as it's fully stripped down the alloy parts are off to the vapour blaster then with luck it can simply be reassembled!

This is the bad cylinder, hopefully it just needs a hone to remove the rust line at the top.
