I finally started on my valve gasket replacement.

I have the plenum almost removed, but there is something binding near the fire wall. I can lift it about 2in.

I don't want to force it. I already removed the large hose in the back with coolant.

What else at the back near the firewall need to be removed?

abalagtas

so....playing around with it more...

it looks like it's binding on the PS corner of the plenum near the firewall....if it's a hose it must be pretty big because its holding it down really strong. It's getting too dark...I'll try again in the am.

abalagtas

ugh...nevermind....found the hose....but broke the pvc hose and intake gasket.

I noticed the intake has a layer of carbon....should I try and clean this? The TB and plenum look pretty clean, but the intake passages are bad.

why are you removing the plenum if you are doing the valve cover gasket? or did you mean you are doing the intake gaskets?

Chaser -

You can't access the passenger-side valve cover with the plenum on. You "can" remove the driver's side, but it is difficult enough that I just remove the plenum.

abalagtas -

I suspect you were hanging up on the PAIR hose (about 25mm, and short enough that it is hard to wiggle). In the future (including replacing the plenum), consider getting a hot air gun (a hair dryer is enough) to warm up all the rubber before installing/removing it. It will not only make it easier, it reduces the risk of damage.

If you've removed the throttle body, take a good look inside the plenum. Many of us have found a LOT of "gunk," with is mostly supplied by the PCV valve. It's worth removing. Remember that the plenum is aluminum, with machined sealing surfaces, so don't let it sit overnight in something with a really high pH (Purple Power, which is generally a good choice, should not be left on overnight). I used a cheap plastic mortar tub and dish washer detergent to good effect.

i suspect the engine is not the 22re, but instead a v6. makes it hard to help when the pertinent information isn't provided, though. i had the same thought - why remove the plenum to change the valve cover gasket?

It's in his signature.

But, yes, getting (good) advice is always more difficult if the basic facts are omitted in the question.

Great idea using heating gun....wish I thought of it before starting.

The plenum and TB look pretty clean, but intake runners have a layer of gunk...should I hit it with TB cleaner and a toothbrush? I wasn't sure if having some of the gunk fall further in to the intake will do more harm than good.

abalagtas

here is a pic of the intake crud.

You can see the TB looks pretty good...the plenum is not as clean as the TB,but doesn't have the same amount of crud as the intake.
