Steve, et al:
I do have some leaks but, the usage seems to be
from driving, not leaking. A few normally
expected drips from a 40+ year old - not
unusual.
As I am a bit nervous about hastening the
demise of the bottom end, I think I will just
continue to add oil for now, maybe 20W50 in the
Summer. She really needs to be completely
rebuilt, but then that drags the tranny in for
a needed overhaul too. See, you guys are great
at spending my money, aren't you! 3K engine +
1K trans, yuck!!
For now, I'm just driving her and having fun!
New tires, wheels, and an entire exhaust
system, are gonna' get my next couple a G's.
I'll let you all know when she blows. (BTW,
anyone have a '65 413 High Performance block
for sale?)
Thanks again, as always, for the advice from
everyone. This is the absolute best resource!
