ok so i welded the mani up. looks ok. but to be honest i wont bother to do this again. the metal is rather crummy and even with my amps down the metal burns out. i had to build the welds up a lot to get all the cracks covered and taken care of.

i will install to morrow and see how long it lasts but for the time and dollar. get a new one. pics and instal to go on tomorrow.

 

dont know bout renix but on my 99 i did it in 45 minutes.
just pulled the airbox, electric fan and power steering pump to make room, took off intake manifold, unbolted te top bolts, raised the lift and then unbolted the bottom ones from below. unbolted the flange from the pipe, yanked her outa there. then i cleaned everything up while i had it out. threw it back together and then did my valve cover gasket

 

My manifold had a nice crack and I ground it down a bit and my dad hit it with the welder also. You are right about burning holes through it, but it is 95% better than it was before and has held for give or take about a year. I had one hell of a time reaching every spot i needed though.

 

and do it again and again and again everytime it re cracks etc. I do TONS of 1 off fab work etc, and just like most people my time isnt "free"


I feel ya on the tinkering and wanting to learn, I did that alot over the last few jeeps, and I've done my share of things twice aswell lol


As to anwser GEE OH DEE. Egg on my face for not clicking the drop down. I was not thinking about the renix. Just the metal tube header on the 4.0

 

well manifold is going in the clave over nite for a stress relife. that will make a world of difference. on how long it lasts. but lets see right.

b.smith i think i will be cutting my fenders and tubing the rear like in your vid. nice walk thru.

as you can see this mani didnt look bad but there were more cracks that showed up in process so these wellds got built up a lot. and a FRACKING hole that wasa bit of a mother ***** but alas i got er did. i'm smooth like keith stone at times ha haha . more pics to follow
