Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I then replaced the steel gasket and bolts but it still continued to leak.

manifolds on these cars are boat anchors that can't even be given away in most cases, so I certainly wouldn't invest a lot of money in a factory replacement or repair unless it was practically free to do so.

header/cat is 16 years old with about 95k miles of use, would I be better off just replacing it with a new one?

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1Original post

Just after I purchased my '05 BS in 2019, I noticed an oil leak coming from where the exhaust header connects to the head on bank 1. I checked that the leak was not coming from higher up on the engine (cam cover etc). I then replaced the steel gasket and bolts but it still continued to leak. I pulled the header off again and put a straight edge across the header mounting plate and measured about a 1/16" warp across its length. I suspect this is the reason why the header gasket is leaking. I'm going to find a machine shop and see if they can machine out the warp in the mounting plate. I am curious why that much oil would be leaking from the air ports in the head and why there was no apparent exhaust gas leakage. Has anybody experienced a similar leak? -RobT

POST 2Original post

Good news and bad news. I took the stock header to a machine shop and they marveled at the build quality and high grade of materials that Porsche used (good news?!). The bad news is that the header flange plate is stainless steel requiring special tooling to machine it. I was quoted between $400 and $600 for setup and machining. Since the exhaust header/cat is 16 years old with about 95k miles of use, would I be better off just replacing it with a new one? Sent from my Pixel 3 using Tapatalk

POST 3Original post

Sounds to me like a good excuse to go get some performance headers (either catless or with high-flow cats).

POST 4Original post

Agreed. Perfect time to upgrade to sport headers ! The factory exhaust manifolds on these cars are boat anchors that can't even be given away in most cases, so I certainly wouldn't invest a lot of money in a factory replacement or repair unless it was practically free to do so. You might find someone with one cluttering up their garage after installing headers that is willing to send it your way, but again just the hassle and cost of shipping may be more than its worth to someone unless its local to you

POST 5Original post

I like your rationale! Any recommendations for quality high flow cats that won't trigger codes? Sent from my Pixel 3 using Tapatalk

POST 6Original post

Both Soul Performance and Fabspeed make performance headers with 200-cel cats. I went cat-less btw

POST 7Original post

An update in case anyone else runs into the same issue with oil leaking from the exhaust gasket. I ended up just replacing the bank one header and cat with an OEM part. After about 100 miles it also started leaking at the exhaust header gasket. The root cause of the leak ended up being worn valve guides leaking oil. I had to have the head removed and new valve guides installed by a machine shop. After 300 miles there have been no leaks. -RobT Sent from my Pixel 3 using Tapatalk

I know this is old thread but it looks like i’m having same exact issue.
