    it looks like one of my oil cooler lines has a small leak in it somewhere, either that, or the power steering pump is sweating. the leak is small enough that i cant tell a noticeable drop in fluid in either, but its gettin my motor all dirty, and i dont like leaks. is either of these common on a 105k mile 97 350 vortec? /forums/images/graemlins/1zhelp.gif

    It's common on every 88+ truck with more than 5 miles on it... I've gone through 3 sets on my old truck and 4 on this truck. Finally had some custom hydro hoses made at the shop I use for my hydraulic lines and no problems since.

    The oil cooler lines started leaking on my '91 S-Jimmy, so I replaced them with new ones. In less than a year, one of them was leaking again. /forums/images/graemlins/angryfire.gif Then the lines on the '94 Suburban started leaking. Rather than spending the $100+ that the GM dealer gets for the lines, I removed the old ones and took them to a shop that makes hydraulic hoses. They cut off the old hoses and crimped on new hydraulic lines, for a whopping $18 each. /forums/images/graemlins/deal.gif It hasn't leaked a drop since. /forums/images/graemlins/thumb.gif

    GM has a SERIOUS quality problem with whoever makes those lines for them. They all seem to leak where the rubber lines are crimped to the metal tubing. At a measly 40-80 PSI those lines should NEVER leak. /forums/images/graemlins/shame.gif
