I've had my C20LET block back from engineering shop, crank, pistons all baclaed up with the new ligter flywheel and uprated clutch plate.
They put all the parts in the degresser and they have all come up nice and clean.
However the engine, when I bought it had been standing for a year, and as you can see from the 'before' picture it was very rusty and scally inside the water jacket and water pump apture.
This is what the block looks like now
Does anyone know how and where I can get all the rusty deposts all cleaned out from the water jackets? I want to do it now as the engine is all in bits.
