Intake Manifold gasket tip (?)

[truckguy94]

Thought I would pass this along.... at stop lights, my oil pressure gauge would drop to the bottom of the acceptable range; I would shift the truck into neutral and the rev's would jump up and the pressure would come back....went like this for a couple of months because I had a cold idle problem and thought it was related to the Idle Control in the throttle body....put off the repair because it was summer and the cold idle was a minor issue.... also had an oil leak and took the truck in to have the oil leak fixed....they tracked the main leak, using dye, to the intake gaskets (and timing chain cover gasket, too), replaced them, and lo and behold, the oil pressure is totally stable ...never guessed the intake was an issue... fyi

intake gasket problems are common on pre's
