Manifold tightening sequence question

I have a 95 YJ 4.0L and noticed a smell of exhaust about a week after I replaced my exhaust manifold. Went in and tightened the bolts back down and a couple days later I started to smell the exhaust once again. I think my sequence is wrong for tightening the bolts and after a little research came across this bad boy:



I think it is a diagram for a 4.0L out of a TJ but does it apply to the YJ as well or is there another sequence I should be using? I came across some other diagrams but they all have the EGR tube listed which my 4.0 obviously doesn't have.

That diagram is probably just fine. But if you tightened the manifold the first time and was good. Drive it and had to tighten it a second time, and now you smell it again? Are the nuts loose again? You might need to buy new hardware and a new gasket.

I still have to check the bolts to see if they are loose, I suspect because I put anti seize on there it may have not helped my case. Also if I suspect if the tightening sequence was wrong that may have also caused my issue, I'll check on thursday and see if they are loose.

Use the diagram and get rid of the antiseize. It isnt unusual to have to retighten after a few hot/cold cycles. Aftermarket headers are really bad for this and its good practice to check all exhaust fasteners.
