I recently had a mechanic replace the exhaust manifolds on my Dodge Ram 1500, 2003.
Since I got it back I noticed oil leaking from bolt numbers 5 and 6 on the manifold diagram.
I can see the oil bubbling around the head of the bolt and dripping down the manifold.
I know the mechanic had to break the bolts to get the manifold off. He was able to use an extractor to remove the bolts; didn't have to retap, use a helicoil, or anything like that. It didn't leak before I had the manifold replaced.
Why is there oil leaking from around these bolts if this is the exhaust?
Update: Last night I removed and reinserted bolt #5. There was Aluminum anti-seize on the bolt. I don't know what the torque spec is, nor do I have a torque wrench that would fit into this space, so I just tightened it. It appears to have slowed the leaking some, I don't see any bubbling around the bolt head any longer, but there is a steady drip from #6 bolt.
