1988 Ford F-150 Repair Question
F150 intake manifold and/or head gasket replaceme
1988 Ford F150 V8 Two Wheel Drive Automatic 166k miles
My truck has developed oil leaks from what I am told is the intake manifold. There is visible oil pooling in the front/upper area near the distributor. Engine performance is also affected as it starts OK but begins to run roughly after warming. I was told that was due to coolant leaking into the intake. I want to replace the intake manifold gaskets but I am unsure if this will require head gasket replacement also. I have searched high and low for repair procedures on the internet to no avail. Any help at this site?
intake manfiold if it was leaking would not get oil in it, it could be excessive blowby by a bad crank case ventilation filter or hose, pcv valve, worn piston rings, OR overfilled oil.
if you replace the intake manifold gasket you dont need to replace the headgasket.
