the squish test.
To check the squish profiling and valve/piston clearance, a bit of plasticine was used. Done it on three pistons (both end ones and one from the middle), to make sure the head and block are all even and not on a funny angle.
Usual process put the plasticine on the valve cuts on piston and the angled edge for the squish band. Put the timing on and give it a full revolution.
Know I know the best way would be to use proper tools to check the thickness, like a micrometer, but im building the engine in my kitchen Razz im not an engineer im a postman don’t have those things lol. Made do with using a filler gage to check the thickness. Pictures show how this was done.
All the clearances were spot on and all even.
engine is in and up running car flew through it M.O.T
