Penguin wroteI went 35-50 miles, I also forgot to post this is an I-6 258.
HOLY CRAP BATMAN!!!!!! I didn't know I had that much IN the motor to begin with!!!!
Other than checking oil (and changing same), look on the back of the head and see if yo have a dribble down on top and bottom of the bell housing. seems the first places I get a leak are the rear of the head (usually cause you can't get back there and retorque the bolts) and the rear main (got that problem now on Erins YJ).
Dropping the pan and checking for shavings and a color change on rod ends might not be a bad idea either.
Jeez, guess I need to re-eval my top end! Polished 258 with webber 38, and clifford intake/exaust - stock cam though :-|
