Ok, I went the cheaper route and had my leaking oil cooler lines refitted at a hydrolic hose shop, both done for $58.00 took me 8 plus hours to get them out and in but hey they are done. Well I didn't catch the fact that the new hoses rubbed up against the fan belt and yes all of my work was needing to be done again since after driving my now oil leak free car for 15 minutes the oil pressure was gone along with 6-7 quarts of Fresh Chevron Delo, so I had a real mechanic do the lower oil cooler line that the fan belt sawed threw. Now I go to pic up the car and it has a loud knocking noise and the mechanics think that it is a valve or a bearing sticking or going bad? Loud knocking that accilerates with the engine acceleration. They say it was because of the 2-3 minutes the car was operating with the leaking spewing oil everywhere oil coolant line. The knock seems to be coming from the #4 piston top end, also noted is that I had the glow plugs changed out and the #4 glow plug would not come out and actually the out half broke leaving the inside stuck. I am not sure if a piece of it is causing the knocking noise or if they are seperate items all together. HELP!
