Ahh .... I don't know what that one is ... I'll stay tuned to this question for my own info. What makes you suspect Oil/Fuel? Smoke? Smoke in the exhaust can be a few things ... most common on High Mileage Chevy's is Valve seals have hardened, cracked and are leaking /// or worn rings


Inquiring minds would like this answer. A '98 Vortex should have no smoke b/o bad .... or even missing .... valve stem seals, since the new Vortex heads design precludes the possibility of oil getting to the valves anyway. The very first, early Vortex engines had lots of oil control problems in this area, but not a '98.


There is no connection from the engine oil and the fuel except at the combustion chamber. If you have blue smoke your engine is burning oil from worn rings or worn valve guides and seals. Black smoke is the car running to rich. White smoke can be a bad head gasket.


If you mean fuel in oil it's inside the upper intake on the back of the Spider injector. But it's not possible to get oil in your fuel, lol
