[DeTomaso] oil leak, any one ever have this happen to them.

One is supposed to touch a brand new filter's rubber seal with the dipstick 
for a drop or two of lube and smear it around with a finger before 
tightening the filter. Most of the time, there's enough residue left on the block 
surface, but now 'n then the rubber seal catches on the metal, balls up and 
can tear (same as I posted about using 'seal nuts' and sealing washers). 
I was once driving another owner's Pantera (hard!) when the Taiwan-built 
oil filter stripped its threads and blew completely off the block at 6500 
rpms. You think you made a mess in your garage.... you shoulda seen the 
racetrack with 8 (out of 10) quarts of 40-wt spread over it.
