Blow-by 

The foul smell of a fart that has gained momentum by passing by a turd before exiting the rectum. Usually accompanied by a prairie dog. Scent is thick, heavy, and smells like shit, rather than gas.

Ashleigh, is that blow-by I smell?

blow-by 

A condition exhibited by a worn-out internal combustion engine when the piston rings no longer efficiently seal the combustion chamber, allowing compressed air and fuel to escape the cylinder and thus power is lost and emissions are increased. The engine also usually burns oil.

I was going to buy that 350 from Carl, but it had too much blow-by and needed to be rebuilt
