I have a 1989 Ford Aerostar that has an oil drip at the sending unit seal.
Only can be seen under pressure, shut the car off, and it's not there, but
you can wipe the drip clean, and it comes back... the sending unit is
right above the drain plug, correct?
Is there a specized tool I need to pull it and replace it? I guess I'd
have to drain the pan first? (do it at my next oil change) I don't want
to break it off or something. also, how does that wire connect? does it
pull straight off, or what?
As of late, my oil pressure on the idiot gauge shows it a bit lower than I
would like... still in the normal range, but I have never seen it this
low... Do Oil Pumps fail gradually, or do they either work or not work?
Is the lack of a good seal for the sending unit maybe causing the gauge to
be lower than it should be?
Also as of late, during the first 5 mins of driving, esp when it's cold, I
get tappets now. These go away within 5 mins, but wondered if that is
damaging anything? Would a new Oil Pump cure the cold tapets? or does it
