Cracked Exhaust Manifold

[nodelay]

Hi there. BMW Dealers have diagnosed a cracked exhaust manifold on my 2007 Z4 and want £1400 for a new one. Question: has anyone tried welding their exhaust manifold to effect a repair before going down the more expensive route of a brand new one?

I'd look for a used replacement before paying that sort of money!

It can be welded no problem. But it's quite a tricky job. Don't let just anyone do it. It will need to be heated first and then welded by someone who knows what they are doin.

I was concerned about this possibility when I had my 2 litre. My independent was very matter of fact with me and said - if it cracks we'll weld it - as if it was no big deal.

It never did but it was reassuring to hear him say it could be done.

Local independent specialist managed to weld the manifold at a fraction of the cost of replacing via a dealer. I needed to have the rear sensor replaced too which was unfortunate, but again great job, fraction of the price - thanks for advice.

Good result - nice one and thanks for letting us know

Just out of interest; What engine model is your Z4, what age and whats the millage?

There are plenty of used manifolds available in the U.S. that go for next to nothing. If anyone needs one in the future, shoot me a PM.
