So I just received the my new RRE header for my 2.4 Eclipse and I was hoping to replace the rusted bolts studs coming out of the cylinder head that you slide the top 6 holes in the exhaust manifold onto...... now I’m not sure how difficult that would be while having it in the car because I definitely do not have a crane to hold to the engine...... but what I was wondering is if anyone here knew where I could find replacement studs and nuts or simply just knew the size of the stud

I belive they are the same as the 3.8L it would be kinda dumb if they did different ones for both engines.

So i wanna say they are M10 1.5 77mm

And its not that hard to change them in the car did it on my 3.8l rear bolts and there is bassicly no room on those but it was probably the easiest thing i did swapping the manifolds

But bassicly to take them out put 2 nuts on them tighten them togeather us the innter nut to losesn the stud the outter nut to tighten.

Use two wrenches one each nut (to make it faster can be done with one) but bassicly go back and forth with the two nuts until it brakes loose. And your good from there. Deffentily use pb blaster and rock them back and forth until they are loose so you dont snap them off

They fit mine. Easiest thing to do is take one out and take it in and match the threads up. Thats what i eneded up doing.

Alright great! Sorry the pics you sent with the box looked like bolts alone but yeah I see! I appreciate that I’m just tryna prevent any cause of leaks and hoping that I don’t break any off inside

I eneded up spraying the studs down letting them sit for like 2 hrs then messed with them. And took it slow.

This! Overnight with some PB Blaster is what I’d suggest.

Then, as mentioned, you can pull them out and match them up to be sure. I’d use high temp anti-seize on the new ones... ;)

Same kit lol. I wanted to swap manifold bolts insted of studs but i didnt want to risk the threads. If it was a steel block i would have.

Thay are super easy to do. Just remember pb blast the hell out of them and id also say toss some heat in them propane torch works grate. At least you only have 8 right.?

Alright short thread goes in and I grabbed some high temp thread sealant but wym you wanted to change studs instead of bolts? There are only studs up top right?? And I have 6 studs up top coming out of block for the manifold to mount/slide onto but this kit only comes with 5 so I’m confused
