will there be issues if I don't replace the exhaust mani gasket and just reuse the one that's there? I have a ton of other parts to replace while I'm in there so more room to work isn't going to hurt. I have a valve cover gasket to replace, oil pan gasket, all four engine mounts, intercooler hoses, and anything else I find that's busted along the way. I have that gnarly rear clunk sound and I can see the front lower control arm vertical bushings are torn, so I'll be wrenching for a while. For a car with under 60k miles, it's been really beat up. Oh and the clutch slips, felt it fail to engage a couple times, which isn't the easiest to replace.
