Then use water.

 

I think i might for the fun of it, but i can't think of anything leaking other than the manifold gasket,being I've eliminated all other leak sources. When it all began, my PCV hoses were absolute toast, and I was hoping that was it, but not with my luck...

 

i have the same code. I ran an automotive smoke machine through the PCV valve tap and found there is a very very very tiny leak on the back side of the intake manifold. I have a liquid gasket, is there any product made to block this leak, maybe by rubbing liquid gasket around the leaky area? or any type of silicone? Im just trying to fix it temporarily till I have time to do a gasket.

 

I don't think you would have room to get any sort of temp fix on it without removing the intake.

For the fun of it, check the bolts holding the intake manifold on. When I did my intake gasket, some of the bolts could be removed with just fingers. I'm sure that was my problem.

 

On the back of what intake manifold? Upper or lower? Are you talking about a vacuum leak between the upper and lower intake, or an oil leak from the valley pan gasket?
