Re: 97 Tahoe oil sending unit
I changed the oil and it seemed to help. I get better oil psi driving down the road than I was getting was 35 to 40 now 45 to 55 at 2k. When idleing in gear 700rpm I get 15 to 20 psi. The gauge still fluctuates a little so Later I'm gonna change sending unit.
I was using Quaker state high mileage with slick 50 then added a quart of resolone. Now using just mobile 5000.
When changing the oil I noticed a little moisture under the oil fill cap so Looks like I have and intake gasket leak to boot.
