Re: IML: Oil usage theories

["Daniel Richardson" <TheRichardsonFamily@xxxxxxxxxxx>]

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!
