Question about Ford F-150
Thank you for responding, I went back to basics. New plugs began corroding on#3 & #7 cyl, causing a short(missfires).Tested the coil packs,& I recalled #3 cyl head was cracked, it was replaced with rebuilt head. As for the oil gauge flucuating, crank shaft bearings pitted and worn on #3 & #7cyl, due to the coolant(an apperantcommon problem..I took the truck in for an oil change,a ctc rookie put 5w30 instead of 10w30 as requested,in which caused the oil pressure to fluctuate. I dumped the the oil put 10w30 in and some lucas. 2 weeks later no ticking noises and no oil pressure changes.thankgod for lucus. its too cold to roll a set of bearings in the driveway. thanks again for your input. p s a 1997 f150 4.6ltr come with 2 sizes of serpentine belts, be careful of which one you install, we blew the bearings out of 2 new waterpumps,and for the last tip, the dealership uses a pair of vicegrips and an extra helping hand to set up the timing chains,that is what i was suggested to do by there top engine tech. prove me wrong. works like a charm.

Check for a vaccum leak at the intake. Spray a bit of starting fluid in this area with the engine at idle. This engine will speed up a bit when you hit the spot! Replace the gasket or put the hose back on. Way you go! Frankster016
