454 chev motor throwing oil into air filter Frank Mitchell 5-18-14  
What should we look at to find the problem

This is an indication That the engine has bad rings.

But it is not the end of the world.

Often on RVs it it is because they havent done any miles for a while and everything is gummed up. DOnt spend a bunch of money untill you have a couple thousand miles on it to see if it gets better.

Re-route the breather hose away from the air cleaner and make sure there is still a filter like the one inside the air cleaner on the end of the hose. I recomend you extend the hose down to the bottom of the frame to keep the small out of the passenger compartment.

Grab a can of TOP END treatment, comes in many brands, will claim to clean the combustion chambers, gets poured in the gas tank or sprayed into the carb with the engine running. The spray in stuff tends to work right away.

A can of Rislone ( Brand Name I use) super oil detergent in the oil. You will have to do an oil change in a couple hundred miles.

See if that helps.

At the end is the rebuild, if your oil change and additives don't work thats what you need.

Good Luck

Look also that it is not reddish liquid. if it is, it is not OIL but transmission fluid meaning your vacumn modulator on the side with the vacumn hose had it last day and just sucking trans fluid into the carb. change it and there should be no "reddish" fluid in the carb if that is what it is.
