Oil smells like gas!

[JCastellaw]

My Oil has a gas smell. Is that a problem???

Stop running the truck and change the oil immediately!

If your carb is running too rich you are not only washing you cylinders with gas and ruining you rings/bores you also run the risk of spinning a bearing with oil that is thinned by gasoline.

How if this thring running anyway? If you have a lot of smoke......

Fuel pump diaphram can go bad and allow gas into the oil too....
Gotta park it until you can figure it out

It's blowing some sut out the exhaust! New Carb floods.

Friend, don't run it with a flooding carb, or a carb that mathematically too large for the cubic inches.
Wayyyy back in 1978 no one told me these things, and I put a Holley double pumper 1100 on a 390. It lasted nearly 500 miles before I washed the cylinders and ruined a new overhaul.

[JCastellaw]

Could it be fouled plugs from running bad gas??? It's not smoking now that I cleaned the fuel tanks out but still has the gas smell coming out the tail pipes!
It runs great now, but the new carb is leaking on the passenger side behind the electric choke!

Carb is new-return it. I got a new, bad one a couple months ago. Throttle shafts were leaking right out of the box.

If you are getting a gas smell from the exhaust, you may need to adjust your carb or do an ignition tune up. Assuming that your engine is in good shape. I have a 400 apart right now that started out as a small fuel pump leak into the oil pan and turned into an overhaul when the fuel washed any lube from the cylinder walls and wasted the rings.

rebuilt engine new fuel pump new 600 holley!

[JCastellaw]

new mallory hei ignition!

[JCastellaw]

would a fouled plug or plugs do it?????

[JCastellaw]

Also, had an older 4180 carb on it till I installed a new 600.
I also installed a new fuel pump and that may be the culprit. Is there a place to send my oil and find out how much gas is in it??????
