Rear main seal leak
I have a rear main seal leak in my 99 454. I have lost 1.75 quarts since April (or 1,330 miles). I have a choice to have someone fix it, or save the money and build a replacement. My question to everyone here is; which would you do? I plan on having the truck forever. Pull boats or toys...- attack on track

rear main seal
If the oil level is topped off and perfect, and the 99 GMC 454 crew dually has been sitting for 3 full days.....Will there be oil on the ground if the rear main seal has even a slow leak? (parked on level concrete) Thanks in advance.- attack on track
