About 2 years ago I had some oil weeping on my stock oil cooler lines. All the reading I did on line replacement seemed like another horror job so I too the easy root and cut rubber part of old lines off and replaced rubber hoses clamping each end with 2 heavy duty clamps. Well going to work today on the thruway traveling 75-80 mph the car started to slow down like it was running out of fuel next glance at oil pressure told me what was wrong no oil pressure. I had to work my way over 5 lanes to side of road where I could not keep it running and it died. I was able to put the oil hose back on again and put 6 qts. of oil back in again it would not start. While waiting for tow which came 2 hrs. later I was able to start it but it did not sound good. I got it towed home dropped it in the street and when I tried to drive it in the garage it only made it a couple of feet and had no power and stalled. Any suggestions as to what damage was probably done and what I need to get this car on the road again or is it the end of the road for this car? Any one know any good mechanics in the N.W. In. Area or someone who could help me fix this car. 85 300 SD showing 270,000 on odometer.
