I've been searching the internet everywhere trying to find the necessary information to complete a report for uni but can't find some things.
Can anyone help out with a few things?
Namely:
What materials the valve springs, camshaft, piston rings, cylinder head, bearings, cylinder block and the crankshaft are made from? We've found some conflicting information and doing hardness tests didn't help much.
This is for a 95-97 Ford Zetec-S 1.4L

thanks in advance
