hello folks, First off, thanks to everyone who so graciously gave me advice in a previous thread.
I got the truck back from the shop again. This time they changed out the rod bearings, which they seemed to think might have gone bad from water getting into the oil when the timing chain *attacked* da motah!
Right after we picked it up, my wife noticed that the oil light was coming on. Sure enough when I looked at it while idling the oil light was on. The dip stick reported plenty oil however.
I called the mechanic and asked him if he thought there could be a problem with the oil pump.
So I asked him what to expect if the the oil pump should happen to stop working while driving. He said that motor would probably make some kind of rattling sound. So I told my wife that if she should see the oil light on and hear a rattling from the engine to shut it down as soon as possible.
Well so far, the oil light hasn't come on again, knock on wood
But she did report to me that it came on when she was driving at a fairly decent clip. She usually favors lower gears and keeps the rpms up a bit more than I do when she drives, so it came on when the rpm's were probably fairly high and continued to stay on even when parked and idling.
Strangely enough, after I killed the motor and restarted,, it never came on again after that for the entire
15 mile drive home.She asked me what caused that. I ventured a theory. When the mechanics changed the rod bearings, they said that there were plastic remnants from the timing chain guides at the bottom of the oil pan. So, my theory was that perhaps a piece of plastic got sucked up into the oil pump and temporarily blocked oil flow until the oil pump eventually chewed it up and spat it out.
Sound plausible? Or is there some sort of screen at the oil intake tube that would prevent something like this from happening?
Thanks A very perplexed --Dave--
