Some early year v-8s had nikasil cylinder liners that corroded with high sulphur US fuel. Better study up on that.

There's a forum called JagLovers or something similar that I posted to recently to try and get some help for my mother's car. The people on that site are helpful, but way off the number of DIYers on this board, so that even what I would consider simple questions are sometimes unanswered.

Try this site, too: motorcarsltd.com

My mom is 70 something and her XK8 convertible rear passenger window wouldn't roll up. The DEALER in Austin wanted $1400 for replacement of the motor/regulator and told her how lucky she was that they had one in stock. I almost hurt myself laughing when my Dad called to ask if that seemed right.

This was before the dealer checked fuses or anything else. So.

I did what I would do with my cars and got online, but as has been said, there aren't a lot of online parts sellers for recent year stuff. This window regulator was a dealer only thing from what I could tell.

I posted a message and found a regulator w/no motor from a recycler for $150 after a few days.

They are beautiful cars. They are not cheap to own. Be sure the engine was replaced if it was one with the cylinder problem.
