The piston is cambered though. ie they aren't a cylinder. The largest diameter is about 2/3 of the way down. How would he know what they're supposed to be at the bottom of the skirt? Sounds suspect to me.
that's why I'm double checking everything here. so how do I know if my piston is fine to keep using? what should the size be?
Got the new fuel pump fitted today on my 1.6 project, going to do a few runs up and down the street first thing in the morning to bed in the rings then tuning on the 27th.
Thanks. If my pistons need replacing I'll probably buy em and have fun driving the car around!I have the pistons out of my engine available. You would need to change at least one of the rods though, destroyed by the run big end bearing. Callum did say that your engine was getting pretty tired Whoever installs the rods has to know what they doing, not to use too much heat.
