Since I consider the combined knowledge here equal to any specialized motor page regarding common mechanical sense, I'm posting my question here. I bought a new F150 with a 5.4, auto trans, tow package, in 02 that has just turned over 300,000 miles. It's never been hot or run low on oil and I've serviced it regularly. I've run 5x20 Mobil One in it since it was broke in. Question is, should I get it rebuilt? Have the timing chains, etc. replaced? Run it til it drops? While it has acquired a few clicks and tics that go away soon after starting, it still has good oil pressure and runs out as good as ever. Could I get some opinions? Thanks! gm
