where's the oil sending unit? http://www.imperialclub.com/Repair/Engine/pump.htm i looked here but noone points it out "Before you pull out your engine, consider that a low oil pressure reading can come from one or more of the following: a faulty oil pressure sending unit, a wrong dipstick, diluted oil, the oil pump pressure relief valve stuck open, a cracked, loose, or bent oil pump suction tube, a clogged oil filter, or least likely worn engine bearings. Your mechanic said that the oil pump screen and suction tube were clogged, but with what? And if that were true, how could that "what" have made it up, through the filter, into the cam passages? If you really have very low oil pressure, then your engine will produce a great deal of noise just running. The lifters would produce such a racket that you would shut it down after a matter of seconds. On the other hand, and some may dispute me on this, if your engine runs and you get no lifter noise, then you are getting at least enough oil pressure to protect and run the engine. There is something, in my opinion, that just doesn't add up in what your mechanic has told you." _________________________________________________________________ MSN Toolbar provides one-click access to Hotmail from any Web page – FREE download! http://toolbar.msn.com/go/onm00200413ave/direct/01/
