Gas In My Oil Oil Thin And Smells Like Gas Please Help
Posted in Fuel Systems & Components | Asked on Apr 19, 2011
Below is the question about Gas In My Oil Oil Thin And Smells Like Gas Please Help, I have a 1980 z28 with a 5.7 liter 350 with an 8 quart oil pan we bought the car about a year ago when we got it we found out that it had way too big of a carburetor for a stock engine its i think a 750 cfm edelbrock but we have never driven we would just start it up and let it run for a while so i just drove it down the road yesterday and when i got back we checked the oil looked dirty but then i smelled it the oil smelled like straight gas almost ..so i changed the oil put stp oil treatment in it and stp smoke treatment then i drove the car about 30 miles and i smell a little gas in it but i never changed the filter (cause stores were closed) so i want to know if this is the rings or is it possible that since the carburetor is way to big it could be flooding and somehow forcing gas into the oil from having so much gas sprayed into it….and the car has no guts sluggish but the carb being to big is that problem i think ?

YOU JUST ASKED THIS!
Sounds like the piston rings to me.
With this being a 1980, the fuel pump can go bad, even tho it pumps the gas to the carb, there is a a chance that the pump activation arm that is run off your timing cam, has a small pin hole leak thus letting gas into your oil. change the fuel pump, oil and filter all at same time, you don’t need to add STP oil treatment, run a tank of gas then change oil again, that will get the oil freshened up.
Yes the 750 CFM is a little big for a stock 350, maybe a 650 cfm?
Chances are that this carb is only METERED wrong for your car. Edelbrock will have a chart that show the proper jetting, air bleeds, and other items that will make your carb a winner. It is NOT really too big, but needs some fine-tuning to match. Carb’s that run too rich will cause the problem you are having. The unburnt fuel goes right into the oil past the rings, and thins down your oil. This CAN be stopped, though. Call Edelbrock directly from the number on the internet. DON’T drive this car this way, it’s an easy fix. Good luck!!
