all the connections are different and cannot go into the wrong place.. if you worry about putting it back together, take a picture of every step and how things came apart, look at them in reverse order to reassemble

Right . And do not use a razor like he did if you do not know what you are doing . Any slice can cause a leak if you do use a wire brush use a brass or softer material then your aluminum manifold: his will eventually leak from the midde

How hard is it to change the valve steam seals? Can it be done by simply removing the cover?

did you ever figure this out? I have the same problem now

Yes

For anyone in the future There is 2 studs . Washer and nut size 15 I believe may be different on your model . 9 bolts 2 studs with nuts all have washers . This dude did everything backwards and wrong hurt to watch idk why i even watched

will dawson same.

Cold be also a faulty fuel inyector Just check voltage to the inyector.

right. i played the fuck fuck game for 30 min with the power steering pump alone.

reach under with a wrench - got mine from laying underneath, you can also get them from leaning over the front and reaching under. I couldnt get a socket to fit tho, had to be a box wrench and a cheater bar.

@@joeldallas6126 thanks man, I ended up using a ratchet wrench ..9 /16 ....changed head gasket , manifold gasket, did oil change and filter.....now my oil pressure is 80+...going to change the oil sending unit now and crank position sensor....found it's easier to change te he sensor from inside the jeep..

Tony Saprano they crack due to the number of heat cycles. Any metal is only good for so many.

@@happyhermit6899broken motor mount caused engine to twist, check your motor mounts, if they are bad, especially the drivers side,your new manifold will crack.

Did you tighten it down good

there is also a torque sequence that you should fallow for installing things like this

I never felt any different it makes that 4.0 sound better though

what size and lenth bolts are they on the down pipe i think im going to get a stainless set

How do you keep guys install one of these header on a 2001 with the crazy dual cats? Thanks.

@Norad Ragok, good question! I have an 01 with that set up, and I hear putting a header on will make it even more of a check engine light nightmare. I have a CEL every other day from the damn heat soak

P. Lanz same

Well let me tell ya from my experience with my 96 XJ 4.0 .. shit don't always go back together that easy and depending on your schedule and funds a mechanic may not be the worse choice. I myself... Struggle, cussing and busting my knuckles, order parts that are (supposed) to fit but don't always without some modifications... So shit 800 bucks sounds like a good idea.

Hey I saw your comment about the bolts/studs being mixed up. About to do this job myself, couldn't tell you how much I'd appreciate it if you could mention some of the other things to look out for or even a more accurate video. I love wrenching on my jeep but if something can go wrong, it will go wrong with my luck haha. Thanks a million!!

Smoked Salmon sorry i forget to check my notifications. Its hard at first but then the 5 next times is easy . I actually was out of buget for gasket and all the tune up items so i cheaped it with the first manifold gasket got some leaks and re did it multiple times till my check came in .oh and DONT OVER TIGHTEN THE VALVE COVER BOLTS TO MUCH. Literally will feel the rubber hit its max squish . If you get that far

Smoked Salmon theres torque specs but honestly think it dont matter just that you follow from the middle outwards . Except the head bolts . Those are important to look up specific specs
