'97 TJ - oil pressure question
Have a 97 TJ 4.0 I6, 162k miles. Recently oil pressure gauge dropping to zero when stopping. Levels off at stop to about 20 lbs then back to normal 40 lb running. Don't really want to think about a rebuild, but trying to confirm my fear.
Ac damper door closes with ac on and engine under load. Back off throttle and door opens. Thinking vacuum issue or damper vacuum switch.
Any and all insight is greatly appreciated. Hobbiest but have rebuilt a Ford 460 which was a blast!
