Alternator
Hello, I am looking to buy a new 911 alternator, or a used one, the cost of new ones is very low considered to the cost of used ones genuine ones, are the new non oem(bosch valeo marshal) good or are they going to cause trouble ?

They are going to cause trouble. I had two aftermarket alternators in one year fail.
Decided to buy an OEM Porsche alternator, though expensive, and know it is going to do the job.

OK, now I am starting to worry about my rebuilt alternator. I bought it from Pelican, a Valeo, and it is going in the 3.2 that is going into my original 914-6. As you may know, the alternator on a Six is right up to the firewall between the cabin and engine compartment. Makes it a tough swap once the engine is installed. The last thing I want, after having the car painted, is to have to pull the alternator out once the engine is installed. I am wondering if I should send out this rebuilt alternator to a local rebuild shop to have them go through it to make sure it was rebuilt correctly to begin with, based upon the above comments.

So following up on my post above, I actually took my rebuilt alternator (from Pelican) and took it to a shop that actually rebuilds them on-site. They found some bad solder joints and said they believe the alternator would have failed in short order. They also replaced an internal bolt that was extra long for no real reason. They re-soldered the joints correctly and then bench tested and it worked like a champ. Hopefully that will prevent any future trouble for me. Cost me $90 - well worth it. I should say that Pelican is just a re-seller and never actually had their hands on this alternator. It was drop shipped from their supplier. The first alternator Pelican had sent was actually damaged and could not be installed at all. The box was perfect and yet the actual shaft of the alternator was bent - so absolutely damaged before it was boxed up.

The large volume "rebuilders" just toss any metal fasteners they have at it, hose it down with molten solder, run it thru a dishwasher or something, and put it in a nice box.
