Hey guys, I’m about to take off my exhaust manifold to get to my PCV valve (which is in absolutely the stupidest place I have ever seen) and just to check everything out, on my 1996 Mercury Mystique 2.0L automatic. Anyway, I know I need a new gasket when I reinstall the manifold. However, the Haynes manual also states (in very clear language) that I must also install a plastic guide sleeve when I reinstall the manifold. See page 8 of this slideshow: http://www.slideshare.net/kerryprinceuk/motor-zetec
The question is: do I actually REALLY need this thing? If I do, where the heck do I get one of them? There are a lot of Zetec engines out there, so I figure this part should be pretty easy to find but my googling has failed me here (checked all the big auto parts store sites, RockAuto, etc).
I’m probably, as usual, too worried about doing this simple job right, but I do enjoy doing things the right way and not having to do them twice (and I’ve never taken off an exhaust manifold). Thanks for your advice.
