Is a cracked manifold a big job to put right ?
Is it a job that can be safely entrusted to a (known) decent garage ?
Does it require genuine parts ?
And any idea of approx cost ?
All answers not on a postcard appreciated.
:) :)

In order:
No
Yes
Probably the only way to get a manifold; the gasket can be pattern
An hour's work? The manifold is likely to be expensive, and it's such a common problem that a used one is not a good idea
-
I have known manifolds on other makes to be welded,but with varying degrees of success.I would imagine that a new manifold would be a dealer only part[could be wrong though]Is a known good used one a possibility-from a reputable source obviously!
-
Just out of curiosity I Googled for the manifold, and it seems that new ones for a 2.2 are available for about £130. Which makes scratching around for a decent secondhand one pointless.
-
Thanks chaps, I just hope they are still available in that case.

Hi
I got an cracked manifold on my X20XEV too. Main problem allways is to disassamble the manifold. The bolts tends to brake away.
I have had some good luck, nothing happend this way and I could easyly take out the manifold.

I gave it away to a workshop for welding. They did a good job. 20€ witout invoice :)
The manifold comes back curved (they told me before), but that was no real problem, because I could planed it in my company.
Installation of course with a new metall gasket (around 20€).
Over the last 5.000 km it works perfekt.

cold stitch welding Is the only proper way that can be repaired :y

Agreed Andy...They all seem to crack in the End

but not knocking metal stitching. Where I used to work we had some big cast cooling slabs, maybe 5' dia x 3"(cold water underneath, hot toffee on top) and one of them had a crack in it. various firms came & looked, said they could weld them and they all failed. A new engineering manager sent them to a local metal stitching place, they made a fantastic job & they were sorted. :y :y

That basic technique is how the Victorians repaired iron castings. No complicated tools, just a drill, tap and some bolts. The air tools and shear off fasteners just speed up the process slightly.
It would be interesting to see how well it works on a thin exhaust manifold. Especially as welding them is rarely successful.

What you think thet are about 2mm ?

Facinating video of cold stitch welding...i saw this done a few weeks ago on the t.v.show....car s.o.s....which had a car that had been standing for many years and it had a cracked block which was several inches in length and they cold stiched that and it worked very well..

I saw that one too :y

Grandad called the technique Boilermaker's stitch and said that using it to repair a cracked engine block was one of his tests when he joined the Ordnance Corps in 1932.
Looking back a few posts at Rolf's photo, trying it on an otherwise scrap manifold would be instructive.

Definitely cracked manifold, although ticking almost non existent after a few seconds idling. Possibly a slight blow from the flexi, but needs a visual check to be sure...

I will get a quote on monday and let you folks know in case anyone else is interested.
:)
-
right, I have two quotes and they are both for £325.
including parts, labour and vat.

You can also weld it if you can get the casting hot enough. I have welded a manifold before for one of my other cars and we had to have it in a furnace for over half hour first to get it over 700 degrees, then weld it whilst putting it back in every 15 seconds or so and then leaving it to "cook" for another half hour before letting it cool gradually. Not the easiest thing to do.
