Customer Question
02 Silverado 4.3 36K miles-shop...
02 Silverado 4.3 36K miles-shop replaced defective "o" ring near oil strainer that allowed oil to drain back into pan after shutdown. Engine would clatter loudly for a couple of minutes until oil was circulated to the top end. Now after repair the truck mostly sits and I've gotten two low coolant level messages and added coolant. It's in another state and my son sent me a picture of the dipstick which looks like way more oil than necessary. Any idea what's happening because the shop owner says they didn't disturb anything that would cause what's happening.Don't want to drive it if the antifreeze is getting into oil.
