Oil pressure was dropping to zero then
back up when stopped. Changed
sending unit still happening. Changed
oil, filter, and pump. Now have no oil
Sounds like a plugged oil pickup screen. Sludge will stop it up and cause oil pressure to drop when driving but come back up at idle.
Only problem is I had oil pressure till I changed everything out and now I have none!
Just need to know what to look at. Clogged screen is not an issue. We cleaned that.
if an elect.sending unit..take it out and try a mech.line and gauge or turn it over with the ign.disconected..might make a mess but is itshooting out oil? also you can pull a valve cover and see if its getting oil up top ???
