"Hello,

Former tech here in need of a couple reminders.

1) Is it still ok to bore only the bad cylinder when a cylinder repair is needed?

2) I'm working on a 2004 25c3. The crank ends of the cyls are tapered to accomodate installing the crank assembly I guess. Do I need a ring compressor or will the pistons slip into the holes? Any watchouts besides bearing locating pins?

Thanks,
Ed."
 
"We recommend doing all cylind

"We recommend doing all cylinders to keep in the engine in balance. But, a lot of shops will do just one and it doesnt seem to make much difference. You don't need a compressor to slide them in and other than lining evrything up correctly, no special watchouts.

One caution though. Do not have it bored out until you have the oversize piston and rings available for the machine shop to check against their bore specs."
