looking at a 1976 911 S Targa

And when you say 'hardly', you mean 'doesn't'. The only drip under my car came from the oil tank drain plug (as I didn't change the crush washer during my last oil change... the dealership was out of stock on it! )

MAS, there is a lot of truth in your mechanic's statement; however the magnesium case of the 2.7 was really pushing the limits of the metallurgy (mag also used on early cars) and tended to flex, shuffle, and warp. There were several modifications that could be made during a rebuild o correct these problems,(align boring of the case halves, shuffle pins, etc) which helped correct some of these problem, and help with the leakage at the case halves, etc. Once Porsche went to the aluminum cases for the 3.0 and beyond, the leakage and other above referenced problems were eliminated or greatly reduced.
Also use of synthetic oil on older cars tends to exacerbate leak problems.

I, too, am a very satisfied '76 911S Targa owner (100K miles). Engine has been great, very minor leaks (one drip per week, if not wiped first). Incredible autocross car; light and narrow. Exempt from most state inspection, eligible for collector (low annual mileage) insurance. Easy and fun to work on. Good luck on your necessary PPI. Contact me anytime.

I bought a 76 911S Targa in 1980. I rebuilt the engine once - the next time I replaced it with a 79 SC engine. That eliminates all of the 2.7 issues and I get another 50 hp. It is for sale, but I have 250k miles on it. Contact me if you want to know more RScottCleveland@gmail.com

the 2.7L motors have a dicey reputation for a reason
the trick is to take advantage of that by buying a non-Calif. emissions car that NEVER had thermal reactors on it for a low price due to the rep; my '75 was like that and all(??) or many 1974's are too; not sure re '76-77
the later MYs do have more rust-resistance
