Welcome. You've got one of the better 928s. Last of the 16v, most powerful of them too.

It seems to be a 'late' 84 (first registered in Nov). Some of the early ones used up the inventory of lower compression pistons from the 83 motors, but I would guess that by the time yours was made, it used the later pistons. It may even be a model year 85. I know they use 'registration year' as year over there. Post the VIN in the "Official VIN Check" thread and you can find out what options it originally came with, as well as the model year

As noted above, belt failure will bend valves. If you don't have a record of when it was done last, replace it. Porsche replacement interval was 50k miles, many folks who don't put many miles on them go for a 5 year interval. Some 'experts' swear up an down that it should be shorter, but they are also shop owners who make money on changing them. A lot depends on the environment. Hot & dry (Middle East or US Desert Southwest) are much harder on the rubber than cool and damp.

If you haven't already, read through the 'new visitor' sticky thread. Lots and lots of valuable and useful info.

The flex plate issue does not apply to manual transmissions. Any load that would be on the thrust bearing would be negated by the fact that the intermediate shaft isn't fixed. It would just pull out a bit. The flex plate fixes the shaft to the fly wheel and allows any tension on the shaft to be carried to the crank. There have been a very few thrust bearing issues with manual cars, but not a real problem.

I don't recall any discussion of this car in the forums. It may have been noted in the "928s For Sale" sticky thread. I don't keep current on that one.

Thank you all so much for the replies, I am really enthused by the friendliness and welcome I have received on this Thread..

I have emailed the Seller about the Belts and any other potential issues / time bombs.. His reply:

Nice that the air filter is new (and appears to be in right side up), but two of the straps are missing. Those are important.
And readily available.

Aha, yes, just seen those.. Shame they're not there, as it looks like a simple job..!

Is that Cross Member / Brace bolted in under tension..? Or can I remove it without lifting the Car etc.? Could do with a refresh..!

Brace can be removed as long as the wheels are on the ground as if not there is a risk of the screen cracking. Paint or powder coat plus new bolts maybe.

Brace can be removed if on ramps or stands; it needs to be stable or level side to side. The issue is for the chassis not to be under any torsion, not to move the car w/o brace in place or windscreen may crack.
At least this has been my rule, "your mileage may vary"

See WSM 10-2 ..... " car must stand on its wheels when cross brace is removed or installed". Do not lift the car with the brace on, and then take it off. Take it off first before lifting, or don't take it off at all. I have always followed this procedure, with multiple 928s, and never had a problem or a bent cross brace or cracked windshield etc.
