My 1997 1500 workhorse lost oil pressure on a wood run yesterday; never overheated, no smoke, no loss oil, but valves clattered. I never change the oil, use cheap gas, run at redline, and beat it regularly...not. Got home and parked her; question is, what do I do now? Am going to check oil for shavings, but if no metal, is just replacing the oil pump on a motor with 98,000mi on it the best course, or should I replace the whole motor?
