Default Re: PCV valve good idea?

I only put in 4 quarts when changing oil. About 1/2 quart stays in the engine between the valve galley and the dipper tray. That gives me 4 1/2 quarts in the engine. This lowers the oil level in the pan. Be sure to check the oil level on the dipstick after the oil change so you will know where the new fill level is. The 5 quart fill puts the oil level, especially when going up a hill, at the rear main causing oil to exit and drain through the bell housing. Give this method a try. It could be your answer.

Other issues could be your mains are worn and set too loose; or, you could have a cracked babbitt on the rear main; or, your rings are worn leaking compression into the pan causing pressure forcing oil out from the rear main.

Best of luck!
