Has anyone taken their intake manifold apart on their second gen? I am going to read over my FSM tonight but I was hoping you guys could comment on how difficult it is, and any helpful tips. The reason I ask is because I am going to put a new intake plenum on my car and I am just wondering if its worth the extra trouble of pulling every thing else and replacing the other intake manifold gaskets.....any input would be great. Thanks.

since you taking it off anyways might as well replace a few gaskets. Couldn't hurt

 

yeah I agree, but I am asking how hard it is to get to where all the other gaskets are for the intake manifold. I can take the plenum off but I need to know how much is involved once that is off. The plenum is just held down by five bolts, then it has all of the AAV/IAC/EGR on the back of it. My question is what is involved after the plenum is off?

 

oh well the only one that might give you a little bit of trouble is the EGR tube. That thing is a PITA to remove and put back. The AAV is just two bolts and a tube, its not that bad just make sure you don't drop those screws.

 

EGR one is probably the most difficult. The rest should be cake. Are you doing the lower intake maniold as well? You might need to pull the fuel rail to do it....but maybe not.

hahahahha....I think we are having a misunderstanding, I know how to take everything off up top. I am wondering what to do after that is done what needs to be done to pull of the rest of the intake manifold. So yes I am asking about anywhere that would have a gasket, so I am guessing that would include the lower IM as well.

I have taken my EGR off several times now and I agree it is a PITA. The plenum that I bought has the EGR nut still on there because the guy I bought it from could not get it off so he cut the tube with a saw. I will be soaking this nut in PB blaster then hitting it with the impact gun.

 

mmmmm inpact gun.

Yeah most likely the fuel rail will need to come out. Good time to do new seals for the fuel injectors for sure.

well I finally got around to swaping manifolds yesterday.....I bought another one because one of my AAV screw holes was stripped. After everything is removed all the coolant lines/egr/everything on the back side of the manifold, all you have to do is take the Five hex head bolts out of the manifold. Once this was done I took off all of the gadgets and cleaned them, I also cleaned the runner tracks with Air Intake cleaner. I got some copper gasket stuff and put a line of that stuff around the IM before I put it back together. While I had the manifold off I had boared out the neck to match the Stanza TB....so I installed the Stanza TB....this is where things got to be a pain. The Stanza TB has different fittings for the coolant lines...and there is no way that I could hook them back up stock....so I hooked up a coolant bypass rather than running the coolant thru the TB, I just hooked the lines together. After I got this figured out (no hard but tight on space) I realized I could not get my brake booster line back on because it was so brittle and had to cut it to take it off....so I had no brakes, until I bought a new section of hose for it ( I also put on new roters and pads this same day so I thought I screwed something up when I did not have brakes).....anyway sorry for rambling, just wanted to let you guys know I did this and I am not ready to comment on the feeling of the car yet, because I still have to get the idle set properly, but so far so good.

 

Werd, let us know how it goes. I'd be interested on your take on things.
