I hate cats. And I hate catalytic converters.  |
What are you talking about? what relief valve is there for excess oil that dumps it anywhere but right back into the oil pan? The oil pump and oil filter are the only things with relief valves in the oiling system. And they dump excess oil right back into the oil pan, to be re used again. Do you mean the positive crankcase vent? "pcv"?
and how does excess oil get dumped right into the exhaust? The pcv system routes oil vapours into the intake manifold to be burned by the engine. It does not dump into the exhaust. least not on any street cars i have ever seen. I have seen a few drag strip cars do that. So far as i know we are not talking about drag race cars though, we are talking about economy type cars.
