Yup, especially when it cracked up first time from a full rebuild. What has happened to our manufacturing base ? the h/c pistons had to come from Israel.
Used to be able to go to almost any motor factors and get pistons or loose rings. Throw a piston on the counter it got measured and loose rings supplied off the shelf. Bit more difficult these days. Nobody stocks anything like that anymore apart from engine specialists and even they only stock popular stuff. Bit of a shame and a sign of the times.
