It's a funny story I bought a rebuilt bottom end from a man in brum that was proper fucked needed a crank pistons rods and shells all they did was paint it up it looked brand new I only found out when I pulled the sump anyways I got all that done and fitted it but it was always mixing oil and water so wiped my new crank etc out so gave it to a builder he had it checked and its cracked in the bore so I was proper blagged by the seller
