OK. I'm about to tackle the PITA task of replacing the gasket on my '04 S oil filter housing. What's everyone's view on removing the exhaust manifold first to facilitate access to the filter housing? Necessary? Good idea or bad?

 

I didn't remove the exhaust manifold when removing the oil filter housing. Major PITA. I can't say if it's easier with the manifold out of the way but it certainly can't be any more difficult.

 

I also did not remove the exhaust manifold to remove the oil filter housing.

To be fair, my car was on a lift and I have a nice selection of extensions, swivel sockets, ratchets and power tools in my toolbox.

 

Tools are not my problem, patience is. Tequila at the ready!

 

You can access from the top. Hard to see so you gotta feel for the bolt heads. I can confirm the exhaust manifold can stay in place.
