Hello, all! My name is Erich and I have a 1993 968 that I just bought due to PO not wanting to put back together the front of the engine. Car is in beautiful condition, other than the disassembled engine.

Welcome, take a look at the post on Alternator not Charging, and replace those wires while you have the car apart.
Also, there is a new owner/member link somewhere on here that has a list of things to look at as you get to know your 968. Don't let the list intimidate you, not all of the things are as critical as the belts and the alternator wire.

Welcome. You probably got a great deal. Many of us have had the front of the engine apart and can answer any questions you may have on the job. I have lots of photos from when I did mine if you need photos of the process.
If you have no record of timing chain pad replacement - Do it while you are there. I would also replace the oil cooler housing seals while there. I did and I'm glad I did. It wasn't mixing oil and water yet but it had to be close to failure.

If your timing belt tensioner arm pad is cracked or crumbling, I just made 20 more of them yesterday. Porsche doesn't sell them so I do. They are on Ebay and made of Delrin.

The pads are part of the variocam system which has a chain , but using a “ timing chain “ terminology may be confusing , our cars have a timing belt .

Yep. I edited it to say belt. Still had my head on the chain and pads.

Well, in fairness, failure of either/ or is timing related anyway, and both result in disaster .
One thing about those pads : the bottom wears out at approximately 2 X the rate of the top ( I still can’t grasp the logic to that, but it’s a well documented fact and very consistently so ..) . The problem is you can’t really see it, unless you remove the variocam assembly, even if you stick a small telescopic mirror in there you won’t have a sufficient view. And I don’t mean to scare anyone here, as either timing belts or variocam pads failures are relatively rare but if and when they happen you’re looking at $ 7,000 - $ 8,000 repair bill, unless you’re a DIY-er, in which case it’ll still be a few thousands. So if you see the top pad with just light traces of the chain tracks on it, and maybe no more than 1mm or so grooves, and also if there are no cracks on the surface , no dryness .. you’re probably fine, but if you have deep grooves on the top and they look brittle or have even hairline cracks, your bottom are near the impending doom category . IMO .

Welcome! Good luck with getting the car up and running.
