4.6 P38 ehaust headers/manifold ???

[ian4002000]

I think I need to replace the drivers side manifold on my 1998 4.6 P38. I don't seem to be able to find any headers ? Do you know of any headers that will replace the standard manifolds?
All help appreciated

Hedman (spelling) do one I'm told. I'd just get a replacement from a breaker. The OEM manifold isn't that bad and the hassle and expense isn't worth the trouble. That's the general consensus.

apparently ive got hurricane headers on my 4.0.
might be a starting point to look

Thanks for the info.
There seems to be a shortage of Right Hand manifolds, does anyone know why ?
Is the Right Hand manifold more prone to problems ?

Symptoms requiring change?They crack at the flex joint.

They crack at the flex joint.
Has anyone got an old leaking Rh Manifold ?
I may be able to get it fixed.

[Hoges]

Can they not be repaired using a TIG welder? (just asking!:angel:) Is it the cast iron or the flexi joint itself has cracked?

They are all stainless tube and mostly can be repaired by a competent welder I believe

[Scouse]

They're not cast iron, they're fabricated. The flex joint itself cracks.


I believe they're stainless steel but I can't confirm that.

[glenhendry]

Yes, they are stainless. And yes as others have said it is the flex joint that cracks. I got a replacement from Lynn Rover in WA.

I still have the old one here in my parts grave in Brisbane, but I was told it cant be repaired.

They're just bent mild tube. Mine were cracked at the welds, so had them repaired with a mig (he was a very experienced welder though).

Mate,

Perhaps some of the early ones were mild steel but most of them are stainless. Mild steel would rust out after 18 or so years :eek:

There was a Service Action on the manifolds IIRC.


A magnet was used to check if they were mild steel & if they were, they were replaced.

yep...mild steel and stainless steel are poles apart:p
