I've posted the "float" question before and didn't get too many answers so here goes again, plus an oil leak question. Just finished an 1100 mile trek and found some things that are a concern. If I go anything over 82 mph, the front wants to lift off or float. It is mostly going down hills that I notice it. If I have torque to the real wheel wouldn't that tend to "force" the front end down some. With Interstate speeds at 75 here it isn't too hard to hit 80+. The other thing I noticed is that I am leaking oil. Just seems to be when motor is running. Hardly any when it sits over night. I tried to tighten any bolts on bottom of engine but it didn't seem to help. I also thought I saw a weep hole. Is there a reason that oil would be leaking while driving? No leak around drain plug or filter either.
