Carry your cell phone with you so when the head gasket finally lets go you can call for help!
Enjoy the driving season and do a serious check with compression and leak down in the fall.

In 1968 I bought a five year old Corvair Spyder with low miles from its first owner, a nurse in Philadelphia. The price was right and it had been carefully serviced by her long time boyfriend. How could I go wrong. About a week later I heard a sharp noise on acceleration. Opened the hood and found one of the spark plugs dangling at the end of its wire. And that's how I learned about aluminum heads, cross threaded spark plugs and heli-coils.

Getting the spark plugs started properly and torqued sufficiently without getting them cross threaded or too loose on a 40 year old aluminum head is not a trivial task. Years ago I would carefully remove the old spark plug ring and fit a new one before re-installing. With new copper core Champion 415 plugs selling for less than $2/plug, new ones go in every time old ones come out.

It's usually number four that gets messed up since it's hard to get to.

When I sold my old '74 124 Sedan, the new owner began cursing me driving it home when a plug blew out of the engine. I have owned TCs with badly mangled plug threads, thankfully mostly parts cars. That Sedan case was really a bummer because it had been such a good car in most old Italian car ways that I'd actually never removed the plugs (and it's not like I'd driven it tens of thousands of miles...it was one of probably 10 carsI owned at the time), but I'm sure it was another case of the same.
