I have been told to just leave it for a while by an indie as the job can be a PITA due to snapped bolts etc, I think the manifolds are original, I had a Dansk Sports exhaust fitted last year so that part is good.

Interesting that you think it's made the car run smother with a better low down torque curve.

I have developed a ticking from the exhaust manifold, it's not bore score as I had a bore scope test done last year and they look almost brand new.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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 1 / ORIGINAL POSTEROriginal post

I have developed a ticking from the exhaust manifold, it's not bore score as I had a bore scope test done last year and they look almost brand new. The car is a 3.4 C4 1999 with 190k on the clock so I think they have held up pretty well. I have been told to just leave it for a while by an indie as the job can be a PITA due to snapped bolts etc, I think the manifolds are original, I had a Dansk Sports exhaust fitted last year so that part is good. Has anybody done this, had this done and any idea of costs for swapping out and any suggestions on some SS manifolds? Thanks

POST 2Original post

Is the manifold blowing? If not leave well alone. The standard manifolds are already stainless steel, that is why they have lasted so long, it is the mild steel strengthening plate that rusts and looks awful. I did this last year. i had to buy the stormski jig £380 plus 2 additional long drill which they do not mention you need to remove the 5 bolts that broke off. On the plus side I do have a pair of brand new stainless steel exhaust manifolds for sale as I decided to put the originals back on the car

POST 3 / ORIGINAL POSTEROriginal post

I think it's the plates but it's a manifold off job to sort either way, what are the manifolds you have for sale?

POST 4Original post

Had mine done nearly 9 years ago: http://911uk.com/viewtopic.php?t=97853 Some info on the job written up in there.

POST 5 / ORIGINAL POSTEROriginal post

Nice write up, thanks for the link. Interesting that you think it's made the car run smother with a better low down torque curve.

This is a source reference. Confirm exact model applicability in the original material.
