    Loosing coolant? Possible head gasket blown!! Intake leak will put coolant în the engine oil...... been there!!

    oil clean , pressure test cooling system shows internal leak looking at truck for a buddy evidence of slight intake leak at lf area ( common ) more diagnostics i guess, been a long time since i seen bad head gaskets on these engines. thx pushrod !

    A combustion leak test will help confirm head gasket issue!!... Can air test misfiring cylinder on (compression stroke) also.... to be sure!!

    Change the gaskets with Fel Pro gaskets, The plastic on the Victor, original gaskets melt and leak. IMO
