hELP i HAVE A 97 ISUZU Trooper and noticed smoke coming from my engine next to the Dipstick. However its not the dip stick that its coming from. Bolts that are attached to a casing where oil is leaking from them and on to the motor causing smoke to appear. I have some People telling me head Gaskets/Manifold gaskets/O rings. I will add some pics soon. Does anybody have any idea what I am trying to refer too? Thanks and I appreciate your help
