Phoned up to pick up the 75 on Friday, only to find out that the blowing front exhaust was a cracked manifold. Argh!
My mechanic was getting his welding genuis to have a look in the afternoon, in the hope he could stitch it back together.
I have a feeling that was the last local track day of the year, too.
Bugger!
That manifold is cast iron and not the good welding kind.
I suspect your mechanic is an "Alfa-specialist"... more even so because a used exhaust manifold for the 75 will set you back the enormous price of about 30 UKP...
Installation time? About 1 hour with thea/coffee-breaks every 15 minutes.

If it is cast, he might be able to stick weld it. Propably safer heat wise than mig/tig welding it.
If he can't and can't find a good replacement, see if this
Much better to gas weld it, heat the entire unit up till it glows (like brazing) to remove the localised heat stresses.
Ah right. I thought it was stick arc for cast iron.
It depends on how good the cast is, an old manifold will have quite a lot of imperfections.
Just collected it. 6 hours too late :-(
He's welded the manifold, don't know how, but he has, and it's running like a dream
Now all I need to do is wash and polish it as it's been sat outside for
6 weeks under a tree. Argh!Have something to add? Share your thoughts — no account required.
