'90 ford 350 dually ,7.3 idi was only spotting a couple weeks ago. Tightened the bolts on the oil cooler in hopes it would slow it down a little. Didn't. Spotting every few feet, working towards a steady stream. Aint no tampons for this kind of spotting have to change the O rings and mount gaskets on that cooler, then replace the coolant , change the oil and filter. This job is more than a day if you do it neatly, have enough kitty litter to soak up oil that has dripped on everything, and the coolant that didn't find it's way into one of the 3 catch buckets . That stuff has to be cleaned up around here , can't have poisoned animals , kids, or water well.
This is one of those jobs you would rather do when you be pulling the motor for maybe replacing a rusted oil pan and gasket, and changing out the crank bearings at 200k at the same time. But that wasn't the case so I changed it "in frame" which it may have been easier to just pull the motor, real tight in there, 2 days on a creeper , really need 3 hands , but got it done. Running good and not bleeding out anymore.
