I just bought a 2002 silverado. The owner told me the injectors, pumps and regulator were replaced 5000 miles ago. Visually it appeared like the covers were off and new things installed. After getting it home and going inside to get my wife to show her what I just spent $10,000 on, I came out to see oil dripping on the driveway... a definite bummer. So after she inspected it and found literally no rust on the body or under the doors she says "How many miles are on it?" I says 320,000.... she asked me again figuring she heard me wrong... nope.
She goes in and I start looking for the cause of the leak. It's coming from the breather. I check the oil and it is at the top of full. I jump in it and drive for an hour and recheck the oil still the same. That's when I found this site and info on an old PI from GM about the PCV valve being stuck and not allowing the PCV reservoir to drain back to the oil pan. I ordered one and took the old one out and a cup of oil drained out and the PCV would not let me blow through it towards the oil pan, the new one does. So far no drops on the driveway tonight.
Sorry for the long story but I figured someone might just overlook this $20 of indigestion relief.
Thanks for the info!
