there is a gasket, but you might not necessarily need to replace it. ive taken my header off numerous times and never replaced the gasket. it depends on the condition of the gasket when you remove it...also sometimes they stick to the head/manifold when you remove it, and it will tear the gasket.

so should i go ahead and buy that gasket just incase

The Nisbro

that's up to you. chance's are it will need a new one, specially if it's never been replaced. i think exhaust manifold gaskets are fairly cheap though.

yeah i just looked it up 16 bucks not bad at all thanks for yall help!

B-Well

the header gasket and cat/header donut can both be reused.
the bolts holding the header on are break away nuts so dont over tighten them either

actually, dont overtighten anything

The Nisbro

this needs to be your overall goal. for some reason i have a knack for breaking bolts...usually important bolts too. needless to say,i invested in a nice extractor/threader kit

Taking off the header is the hard part. Make sure you start with middle bolts on the pan. I can have a print out for you with directions from Shop Key 5(including torque specs.). It will be $5 or you can use Google, but if you didn't know how to change an oil pan; I'm pretty sure you can not find it on Google.

3-Profit!

Just go to an auto parts store and buy a shop manual.The ones they carry aren't the greatest,but they're cheap and outline every procedure a novice mechanic would need to do to their car.It includes torque specs and tightening patterns,fluid capacities-everything you need.If you really want a good manual that outlines EVERYTHING,go to http://www.helminc.com and get a factory manual.For about $70 it's a ton of good info.

If I'm not mistaken,the Y8 has an aluminum oil pan,so be careful with beating on it to break it loose once the fasteners are off.This car does have a two piece manifold,so you may find it easier to just remove the lower half.
Replace any gaskets you take off while doing this.No reason to go back through and do it all again to replace one that's leaking because you reused it.They're cheap.
