Hmm small problem

Inspecting my valve caps and collects just now, I noticed the No1 exhaust collects have split and lost the bottom retainer ring a while back, appears the remains of the collects have been moving upwards on the valve stem and grooves...

Don't like the look of it at all! Says the valve is about to drop to me....Rest fine.

Might see at the trackday in the Alfa :(

I have some spare collects, but no specially cut valves prepped, no spare head gasket here, I have a spare valve I can cut tomorrow at the shop, hopefully just the collects are manged and the valve is ok...

Later I will knock up a tool? to remove the valve caps in situ, I hope, can't be arsed pulling the head. Hopefully I can lever the cap off....

Arsecakes!
