Who was following me to a show. Any suggestions on what would cause oil from the exhaust pipe.

When driving oil leaking can end up on the rear of a vehicle and for sure end up on a vehicle following. You might look at the rear main area, oil line connections, valve cover gasket and side cover gasket. It might help to take the truck for a good ride and get things warmed up good. Then park and start looking for oil leaks. | | | | | Joined: Jan 2006 Posts: 24 Wrench Fetcher | | Wrench Fetcher Joined: Jan 2006 Posts: 24 | I do have some slight oil leaks but the oil is inside the pipe so I'm thinking some thing internal. Not sure where to start looking. Valves, head gasket, oil pump pressure? | | | | | Joined: Feb 2004 Posts: 29,821 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,821 | How many miles do you have on the engine since it was built? It's not uncommon to have some oil consumption during break-in, but yours sounds like it's a little excessive. Bad exhaust valve guides and/or valve stem seals will allow oil to get into the exhaust without being burned in the combustion chamber, also.

Next opportunity I have, I will check spark plugs to see if they are fouled then pull the cover and check the seals with compressed air. Just having too much fun driving it right now. | | |
