Looks primarily like a gasket issue ...

You try to save money by going with a cheaper part but then go through grief with install and/or results. I've learned that if you want it right, you need to go with a reputable part or vendor.

I had a repair/inspection ticket dilemma recently... my OBX header had the same look. I lined up the gasket for shiss and gigs, and they didn't line up either. Nor did the new gasket. I had to awl the gasket openings a bit to prevent the new one from doing that.

W/O seeing it I've no clue.
Is the gasket hanging into the runner or missing the flange completely?


What this looks like to me is there is too much stress on the collector flange. This redistributes that stress to the header flange in a forward direction. That lifts the header flange away form the head and causes a leak.
It's the reason for the factory bracket at the collector location.

I know it's the reason I went through 2 Focus Central headers. Both broke the welds at the collector merges. If I had, or if I could have got it to fit, the factory mount they'd of lasted longer.
The other car has some ebay header on it and I know the bottom is leaking near the head. If I lift the collector I can head the leak go away.
Problem is the factory bracket doesn't fit with any aftermarket header. So you have to make a sandwich style.

So if I'm understanding all this right it's best not to buy an ebay header

It's best to buy nothing from ebay.
The site has sponsors that cater to our cars and do provide our community with quality USA made parts.
