I'm about to buy a 270,000 mile '76 911 with stock 2.7. Engine was rebuilt with all the best stuff-correcting all 2.7 issues-at 140,000. Owner has told me of an apparent exhaust leak that no one has been able to figure out, and I am worried that the sould might actually be a broken head stud. Strange thing is, engine is strong,160-175 psi on all 6, and oil reads 50-60 psi at 180 degrees. Am I just freaking out here, or do I have valid concern? What would you all advise me to look for, and how do I check it? Sadly, I can't take the thing to a spcialist for a pre-purchase inspection because I can buy it over the weekend, and no shops are open. Please advise.
