1995 buick century, 3.1l V6 time to change the head gasket as im starting to get white coolant smelling exhaust with a tiny whiff of gas missed in as well as rough idle.
there are two different gasket sets available as im trying to figure out which set to get.
First Design; With Ball And Pivot Rocker Arms; Without Push Rod Guides On Intake Gasket
Second Design; With Roller Rocker Arms; With Push Rod Guides On Intake Gasket
any way to know which i need without getting elbow deep into the engine before hand?
perhaps by VIN, 1G4AG55M6S646XXXX
