What's wrong with this header?
 
I got my Jackson Racing header today and everything looked great until I noticed this...

http://www.mini2.com/galleries/data/...ll_header1.jpg

There is a 2mm deviation from flat at the 2/3 exhaust location...WTF? I checked my stock header and it's perfectly flat:confused: The flange is very thick so I can't understand why there would be such a great deviation...

What do you guys think?

It's ugly.

Did I win?

If you don't trust an RMA you could have put on a head surfacer. I don't it would make it heat warp since the plate is as thick as it is.

JoeCool Oct 9, 2006 12:48 PM

That has got to be a manufacturing defect, although I can't believe a flange that thick would have warped as the primaries were welded in place...Time to call the vendor for a replacement!

Good catch; it’s wrong for sure. I had a Milltek that was untrue also; it’s not that uncommon.

minimusprime Oct 9, 2006 12:51 PM

holy crap... yeah that is definatly manufacturers defect. I also find it hard to believe that it was warped due to primary welding. If it wasn't you assume they would have checked either a) the trueness of the exhuast flat location b) the final product for qc before shipping.

scary stuff.

a big hammer? tighten bolts till it fits? or you can try to do it the right way and ask for another one :p

MSFITOY Oct 9, 2006 01:01 PM

Oh crapppp.....:mad::sly:

Bahamabart Oct 9, 2006 01:05 PM

I guess thats what they call a manufacturing defect :wink:. How much was that header:roll:?

one word - OBX:eek2:

Dr Obnxs Oct 9, 2006 01:17 PM

They don't make a hammer big enough

without going to power tools. And the bolts would just pull the metal out of the head.... RMA here we come!

But, better to find this now than when you can't get rid of the leaks....

Looks like your table is warped

JoeCool Oct 9, 2006 01:21 PM

Just out of curiosity, why Jackson Racing? I must admit, the design is unique among 4-2-1 designs for the MINI and I am (or at least was) tempted to order one myself. Do the ball joints use donuts like the OBX?

Looking at the pic, I don't see any flex type connection point.

scobib Oct 9, 2006 02:21 PM

It's got a ball socket...

SpiderX Oct 9, 2006 02:23 PM

Hey Sid,

Milltek replaced mine under warranty....... what's up?

Mini Mizer Oct 9, 2006 02:23 PM

with a flange that thick, it probably never got the surfice machined to flat. Or...maybe they just like giant non-flat flanges? :confused: :lol:



Im sorry to see your bad experiance, i know thats a real bummer to get a new product and then turns out, it is screwed up somehow. :sad:

hope you get a replacement soon! :thumbsup:

Haven't heard back from them...

herbie hind Oct 9, 2006 03:16 PM

i'll bet that is from welding the beads are waaaay heavy at the top and look at the heat spots at the same place.

I was thinking the same thing, it looks like it got REAL hot where the (incomplete)beads are.
I would definitely get another one, and then have someone who knows what they're doing finish the beads.
That sucks, Sid

obehave Oct 9, 2006 05:19 PM

If the flange is uniformly thick then it is warped. Almost certainly due to welding.
Is it twisted as well? Not that it really matters but I'm curious.
Definitely send it back.

One-D Oct 9, 2006 07:30 PM

THat tends to happen when you don't cast and do a lot of finishining machining to make it as flat as possible.

Instead of making a big deal here-- email them the pic, take another pic and if you have one... but a millimeter rule next to it. Call them up, explain the situation and have them replace it.

Good luck!

The table's straight thank you:roll:

Grassroots Garage Oct 9, 2006 07:44 PM

Well I'll be #$!&%'d , so it is... I just straightened out my monitor, and table went with it :impatient

jlm Oct 10, 2006 03:56 AM

welding distortion would have warped it the other way.

Bahamabart Oct 10, 2006 07:08 AM

Just goes to show that there is no relationship between price and quality!
Ya gotta wonder if this is their production quality, you gotta wonder how much effort they put into design quality? :roll:

Its unfortunate that this happened to you. Thank goodness that you caught it now as opposed to when you were trying to bolt it up.
