Not my Camaro guys but my new toy. My chevy luv is getting gas into the crank case?! I drained about 11 quarts of fuel mixed with oil from my truck over the weekend.:( There was so much fluid in the crank case that it was coming up into the vacumm lines and choking out my carb. The truck seems to have an electric fuel pump. I can hear it go on when I turn the key to ACC. The only culprit I can think of and that has accses to the oil pan is the check & relief valve. It has the fuel line coming from the tank to the valve and the vacumm line going to the oil pan. But before I pruchase the part I'd like to make sure that's what it is.

Here's a guide of the vacumm hose layout under the hood and you can see the check & relief valve that runs to the fuel and oil pan.

Here's a pic of the valve itself. You can see the one line that comes from the fuel tank. The left one on the top runs to the carb and the other runs to the oil pan.

As always all help appreciated. :|
