Cracked Header - Jeep’s Big Blunder

There are really only two types of Jeep Cherokees in this world, those who’s headers have cracked and those who’s headers will crack. Unfortunately, the inline 6 cylinder, while still being bullet proof, has one huge flaw. Due to the nature of the inline 6 being quite long, it puts an abnormal amount of pressure on the header.

The Problem
The break usually comes very close to where the two pipe from each side of the header meet. If you have not had a header crack on your inline 6 you are in one of the following positions: it already cracked and was replaced by a previous owner, your Jeep Cherokee was built after 1999 where they changed the casting, or you have just been lucky so far, so congrats.

The Solution

There is only one solution to prevent this from happening.  Immediately replace it with one like this Exhaust Manifold from AutoParts123.com.  This design has two accordion like pipes connecting the last ports on each end to the rest of the header.

However, there are two solutions to fixing this after it happens.  You can again purchase and replace the header with this Exhaust Manifold from AutoParts123.com. Again this design will not have the same stress on the header as the OEM’s inferior design.

In some cases you can have the crack welded and not only with this fix the problem of the cracked header, but in most cases the extra weld will reinforce that area preventing it from cracking in the future.  Obviously the latter solution can generally be easier on the budget, especially if you have the expertise and equipment to weld it yourself.
