When the engine
is warm the oil pressure drops to near zero when RPMs get over about 2500. I push in the clutch, the RPMs drop and the needle goes back up to normal
JA: How old is your oil pump? Has the check engine light come on? What is the model of your '500 Toyota?
Customer: 1991 Toyota 4x4 pickup, V6 oil pump is probably 80 - 100,000 miles Check light has never come on
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: Oil changes, different viscosity oil. Looking for ideas on what may be causing it. May do it myself, may get a mechanic involved depending on the work involved
JA: Anything else you think the mechanic should know?
Customer: I've owned the truck since new. This started about 10.000 miles ago and I've done the clutch dance since them. Nobody I've talked with can give me a starting point to see what is wrong.
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Toyota Mechanic about your situation and then connect you two.
