Re: 3.7l performance love

I spoke to a local mechanic I deal with and he wants $600 for the install. Too steep for me. So I will need to find someone else that can help me with the job or else I won't be doing these headers.

If that guy on Ebay pops up that he is selling I may jump on and see if I can figure out the labor aspect afterward. So couple things need to click in order for me to do this mod.

Jeff - the header mod worth the costs and effort and gain we will get out of our motors?

Yes. They are definitely worth getting bro. I was curious how muh a shop would charge and its about the same lol. So i did it myself. Its actually pretty straight forward to do and the longest part is getting the stock manifolds out

Jeff - Let me know how you tackled the job. You have a lift? Air tools needed or you did with standard ratchet/socket sets?

Mine just like everyone elses Im sure is rusted to crap. How difficult was the crack those bolts off? Did you do from top or bottom? I was checking out and appears for passenger side anyway you can get to bolts from the top. Unboting the exhaust pipe from the headers I imagine could be a PITA.

Give some pointers on how you took on the project if you can. Maybe I will just attempt this on my own.

Thanks bro.

I plan on doing it with myself BUT I'm sure I'll bribe josh to come down with lunch haha. Also plan on heading to my buddies house and borrowing a couple of tools we might need and go Power tools I got some arm grease but I'm trying to work smart I know for a fact Jeff told me you'll snap some bolts due to rust

Thanks bro.
Here what i did and used....

Only useing hand tools to complete the job. No lift is needed but will make life easier.

As you had stated, the bolts are rusted to hell. So on a cool engine spray every bolt and nut on the manifolds to the y pipe in wd 40 or pb blaster. Let it sit for a little while. (30 min should be good) start with the y pipe bolts as they will be the most difficult ones and you will likely snap em. Once you get the y pipe bolts out, move to the nuts holding the heat shields on. Once they are off you will not be needing them again. Wont fit over the headers. Coming from up top, start working the top manifold bolts out, it will be very cramped. Especially on the drivers side. Then work the bottom ones from underneath.

On the passenger side, once its off it should drop right out but if it dont. Feed it along the frame rail towards the radiator. There should only be the heater core lines to slightly move out the way. The right side must go in from the same way. Slid along the frame rail to the head.

Drivers side. The starter must come out. And the header can be dropped straight out the bottom. New one goes in the same way. This is where you will need to check clearence on the steering shaft bracket. Mark and indent if needed. If not install the bolts holding it to the head with the gasket. If it helps place the gasket on the header and use a bolt to help align it on the head.

I recommend replaceing the grade 5 y pipe bolts for grade 8 ones. Ive had the grade 5 ones come out going down the road. Problem is solved with grade 8 ones. Also recommend having a buddy help as the second pair of hands will be usefull in lining everything back up.

Did mine on the ground in 4.5 hrs witht a buddy

Thanks for the details Jeff. Perfect detail. Did you need to dent the drivers side header to get installed into your WK? Why would some folks need to and some not as the design of all are the same I would gather? Catch there is that if I do this I will be professionally getting the headers ceramic coated prior to install which will cost some coin. I won't be able to hit the header to make that dent and will ruin the finish. I also can't do the job and let the truck sit so I can confirm measurement as then it will take too long for me to finish the job while my headers are getting coated. I need my Jeep for business travel and daily use.

This is a toughie. Sounds simple enough and straight forward but just takes time and patience. Those rusted bolts sound like a bitch though. What you use for leverage to turn them off? You only used the grade 8 bolts on the header to exhaust line y pipe? Not also to attach the headers to the engine itself?

I didnt dent it but i need too. My header just barely kisses the bracket. For leaverage you can use another open/box end wrench. With the box end of one wrench on the bolt, put the box end of another similar sized wrench on the open end of the wrench on the bolt.

There was some slight changes made in the o8 and up but to the extent im not sure. There was a handfull of things changed just in the 3.7 alone.

I'm guessing only 08s and up need the denting
