there is no way that she lost 5 qt of oil out tha pcv valve. i have put in a breather instead of the pcv valve and have had no oil loss in 2 weeks. i have lost oil from the pcv valve sticking ,maybe a quart or a quart and a half in 1000 miles.
there has to be an oil leak in order to lose over 5 qt in that amount of time. shawn
