Hi

Can anyone tell me if en1a leaded steel would be ok for cylinder liners as opposed to cast iron. The piston would be aluminium with cast iron rings

Thanks

I have used it on model aero engines with all iron pistons and it's quite happy at 8000rpm so should be fine on a slower reving engine like your marine one.

Allow about 0.003" per inch dia on the piston so it can expand.

Yes that will be, I'm not sure if en1a is better or worse, I suspect the answer is application specific.

Hi Jason

Were you using CI pistons lapped to suit bore and no rings ?
