Re: REPLACING A PISTON ON A 1997 Spider 2.0 TS
Pistons do fail individually - usually as a result of lean mixture in that chamber, most likely related to a failed injector.
Procedure is head off, sump off. Undo the big end bolts and push piston up. Measure cylinder for wear, if it doesn't need a rebore or a hone - which would be related to wear, not damaged piston unless you are unlucky and a part of the piston has broken off and is bouncing up and down the chamber scoring the cylinder walls.
Get new piston, new rings - size all dependent on the wear of the cylinder. Fit the rod to the new piston, get new big end bearings, refit by sliding piston down into the cylinder and use new bolts for the bearing cap is I'm sure they are stretch bolts.
Easy, done it many times on various engines following a single piston failure. Mostly on turbo engines though, not NA.
