I just did this the past 2 weekends...expected a 4-6 hour job...got a 2 weekend job (had to order some parts inbetween). Ended up taking the manifold off and putting it on 6 or 7 times total. Learned a lot about what not to do though. Here's some tips i learned during the job.
First and foremost...check out the pinned post from VS...lots of pics which make a lot of sense when you're into it:
pcv replacement pics
Disconnect negative battery terminal first (second after reading the post...but it does mention that)...i got a nasty spark when going for one of the lower 12mm bolts... still not sure why but i learned my lesson. mad.gif
To disconnect the electrical connectors to the injectors first pull off the press fit sheilding piece. Just pull from the lip in the back of the cover towards the front of the car. It will pop off w/ a little gentle persuasion.
Before you pull the fuel rail, put a towel on top of the manifold so that if any injectors, spacer rings, O rings, etc.. fall, you'll catch them. After it's re-assembled...make sure you check for injector leaks from the rail or manifold. I almost had a very bad day due to that.
Disconnect the coolant line on the passenger side when going for the lower manifold bolt on that side. You can barely see it if you look from above. A U-Joint works wonders here (and on most the other lower 4 of 7 bolts).
Check all the vacuum hoses for splits and stuff while you're in there...if they're looking bad...replace them.
Get some regular hose clamps that you can tighen w/ a screwdriver or hex driver. I ordered the kit from FCP and got those other clamps... was never able to get them 'crimped' over the lines... Plus the normal ones allow you to loosen them easily to adjust if necessary.
While you have the manifold off....clean it up really good... i went through prolly 2 big cans of carb cleaner. Cover up the valve ports and clean on the block side... This seemed to make a huge improvement for me in respose time, power, etc...
When putting the manifold back on (or taking it off for that matter)...no need to totally take the 4 lower bolts out....manifold is slotted so you can put these in to help locate it. I lost about 3 of them trying to take them off then putting them back in blindly. After i learned it was slotted...takes 1 hour 15 minutes to tear down and re-assemble.
Get all 7 secured before going for the 2 lower ones (oil dipstick and bracket). They are both slotted so there's some room for postioning them.
For me, starting the EGR bolts were the toughest to thread back in. I found that Cranking down the manifold so there was little play helped (egr line is slightly flexible).
and for me...most important lesson was... The lower bracket on the driver side that shields the pcv lines goes on the OUTSIDE of the manifold. I screwed up and put it between the manifold and block the first time and took me a day to figure out why it wouldn't even idle on it's own.
2nd most important lesson...don't overtighen the bolts... i snapped the head off a fuel rail bolt. It was easy getting it back out (beginers luck). It still drove...but after the first time of almost burning my house down i was really sketchy about driving it.
I took a bunch of pics...and can post some if you have more questions.
Here's some random ones...although links will only work for the next month or so. if you want specific ones posted, lemme know and i'll put 'em up.
