OIL PRESSURE PROBLEM...
Hi, my question concerns a 1999 Chevy Express G2500, it's got pretty high miles 270,000 or thereabouts. A few weeks ago I cranked her up and there was a loud noise like an unbalanced washing machine (a heavy knock/scrape sorta) I jumped out and looked under the body to find oil shooting out everywhere: blown gasket on the oil filter. I replaced the gasket and added oil, but the sound would still persist for a minute or so when I start the engine on a cold morning, but after a day or two went away. Then yesterday morning the sond returned, once again lasting only a minute or so on a cold start, but I checke dthe oil upon arriving at work to find that I was a quart or so down... not good. I added oil, but the sound is still occurs. Also, since the sound has been back, when I first sccelerate in the morning, the oil pressure shoots up to the top of the gauge, 80 pounds or so, ugh. After a few minutes of driving (when the engine warms) it seems to stabalize out to normal levels. Though the water pump was replaced about a year back, there seems to be a new coolant leak somewhere, though I can't seem find any evidence on the ground either at work or home. Help!

Replaced heads on 4.7 and found lots of sludge on heads. Once completed and truck runs good but after it heats up the oil pressure drops off to 0. What could be the problem?
