We are still asking: What did you get done on your Bolt today ????

"Whatcha do on your Bolt this weekend?"

I removed my intake and exhaust manifold to clean and evaluate and there is a big crack in the exhaust manifold, see pics below. I assume I need to replace it but figured I'd ask if it's repairable, or if it is, whether that's even a good idea. The crack wraps around most of the manifold although I cannot flex it by hand (I didn't try to snap it in case it can still be welded).
If I replace it, should I look for another old part or is there something new I can bolt in its place? The intake looks OK.
That crack is in just the right place to put in a divider baffle to make a split manifold for dual exhausts. Otherwise, look for a replacement. There are offshore "clones" of the old cast iron dual exhaust headers, but they're pretty poor quality and don't fit well. The supply of original equipment single exhaust replacement manifolds and the Corvette six cylinder dual exhaust system dried up years ago. Good condition used ones are available- - - -try a "parts wanted" post here, and search Ebay also. Jerry

When you get a new one and you are not going to do anything with the old one I would salvage the spring and the heat riser flap and weight in case you need it in the future.

Good tip thanks. Those are all in good condition and functional.
Henrythe wound You could bolt that to a head,take a blue blade (thin grinding wheel) cut it completely in two weld with stainless. The trouble is the casting has lost most of it's carbon and is brittle now. Like us we've lost most of our carbon at this age LOL. Best bet is find a clean,straight,not to rusty replacement. Have several but there 2000 miles away, and are well rusted !!
They’re so plentiful I don’t even save them anymore if I scrap an unrevivable engine. I live in the city and don’t need codes officials breathing down my neck over parts I don’t need.
I invest my money in precious metals, mostly rust!
