Exhaust Manifold Replacement

[east high]

I just did this job two weekends ago. I decided not to remove the wing as mine is a LHD and all the steering bs would still be in the way. I recommend soaking the bolts with some PB Blaster or the like a day or two before tearing into it. There's a chance you'll need to replace some of the hardware too.

Reassembly is much easier if you loosely install the exhaust manifold first before sliding the intake down on top. Those little spreader nut/bolt things are a pain to get started with both manifolds in place. Remember to keep it as loose as you can as there are two locating dowels on the head you need to sneak the intake by.

My S109 has developed a leak around the exhaust manifold. It looks like some type of silicone sealant was applied to it before. The mating flange to the exhaust pipe also has one of the corners cracked off so I am replacing the manifold.

I have purchased the manifold, fixing kit and gasket to replace the manifold. Is there anything else I should pickup prior to starting work?

I will review the manual but would it help to remove the drivers side fender to get easier access to the manifold?
