Hi Gents, looking to purchase my first Porsche.I'm presently looking at a 2 owner 1982 SC with 116,000 miles.The body/interior are very clean.The chassis itself has a long list of high quality upgrades for track use.The owner has shown all recent receipts almost totaling $15,000 between rear axle replacements, all engine seals,tranny rebuild,K-Jetronic control unit, new clutch,suspension,brakes etc...

What concerns me is nothing major has been done internally of the engine top end or bottom.He has used the car for 17 DE events.He has religiously changed the oil after every track event using Mobile1. I've been told these engines are bullet proof but I'm still concerned.I have to think things in the top end like the valve train and heads have to be worn. No upgrades such as new head studs or cam tensioners have been done.The plugs appear to burn pretty clean and I haven't seen any tell tales of the motor burning oil.I do plan on having a PPI done.

I'd really appreciate your experienced thoughts on what I should be looking for and what I should be prepared to spend on this motor in the near future.

Thanks
