Cracked manifold

[JosephB]

Ok, I just wire brushed a manifold and I noticed a hairline crack. It runs between #2 and #3 cylinder. It is realy small but it it about an inch long. Is this something to be concerned about? I thought I had an E6 manifold but it looks like an E3. I put a die grinder to the opening to make it look almost like an E6.

Almost every e3 manifold has cracked in the same place, it dosent hurt performance, maybe 1 hp. Opening the hole will only improve performance, If you are worried about it, just save up for an aftermarket header.

mine was cracked almost completly in a fully circle in the manifold...only thing it did was make a noise when i got on the gas is all.

any exhaust pressure that leaks out of the manifold is less force that spools the turbo...

Most E6'a crack between the #3 runner and the turbo flange. Your's doesn't sound to big and I doubt it'll affect performance noticeably on the street. I'd run it for now and save your cash for a Bob's log or header, down the road.

I'm currently in the process of porting my E6. Should be done by Friday and will have a tutorial up by the weekend.
