Looks to be too much extra metal in there

my pistons looked like that first time my engine went, turned out being the valve guides were broken and had got down to piston then all got smashed up.

the head gasket (metal cometic HG) was the incorrect bore size for the 88mm bore of the engine.

All 4 pistons were scored, block was scrap etc.

you would never hear det without cans on that car/engine. It is VERY VERY loud

the engine sounded fine round the track, then just started rattling and banging in the pits at idle speed

id rather split it than pay for it.

I'm just stripping it and fault finding just now before taking my finding to wallace if there are signs of there workmanship being at fault.

If its something just gotten into the cly through the TB's fair cop - strip the car or plonk a std c20 in

couple of things that could be, take no2 piston out, you may find that a ring has broken up, or maybe a piston skirt has come apart?
