Removing the intake

Hey, I'm about to start removing the intake and know i need a torx set (spelling) would a metric one be what I need? also any other specific tools you guys would reccomend I have on hand?

also the haynes manual says that you need to remove the valve covers and drain all the coolant to remove the intake, but I cannot find mention of these steps on pennocks where this is covered.  Is this really nessessary?

Thanks,

Ryan

You need to be a bit more specific than that. This intake is made up of three sections.

What exactly are you doing?

 

oh, nm.  Feel quite stupid right now, to get to the injectors only need to remove the top part of the intake and the haynes instructions are to remove the whole thing, sorry guys

 

What are you going to do with the injectors?

 

still debating on whether to get them cleaned or just put new ones in, either way i'm going to stick with the 19# ones as i'm switching to the 85 ECM with david's chip.

I'll phone around tomorrow and see what I come up with, and start pulling things apart ,

anyways I'm going to go catch some sleep, goodnight 

I've done this twice on two different 2.8 engines. In both cases the upper plenum just popped off when everything was disconnected. Didn't even hurt the gasket. No sealant such as RTV had been used on either.

You might want to try unattaching the TB from the upper plenum (remove the two mounting screws) so that you can more easily (perhaps) detach everything else from the TB once the upper plenum is out of the way. Of course, you don't really need to completely remove the TB for what you're doing, but it would be a good opportunity to clean it up, paying special attention to the IAC passage.

You might also wish to permanently disconnect the two coolant lines that go to the TB if you still have them. This is a common procedure with 2.8 owners.

You don't need to disconnect the EGR tube from under the plenum to pull the plenum if the tube is disconnected from the EGR itself.

You're going to want to pull the distributor anyway as it needs to be out of the way to access the cold start injector. Keep in mind the cold start injector could be leaking just as easy as any of the other injectors.

Just be very careful you don't crack or break any of those plastic vacuum lines. They are VERY brittle!

This is what you'll eventually be seeing (well, maybe not the badminton racket)...

oh yeah, sorry I forgot about this thread,

So far Ive taken off the intake had the injectors cleaned then reassembled everything, blocked off the EGR, but left most of the hardware in place (just in case i fail nox ) and now i'm just waiting for a new chip and to finish the interior work before air-careing it again.  lets hope it passes

Thanks again for all the help you guys

pretty much the same position as before, engine is all done, interior is now done to the point of being driveable (still need to relocate some of the stereo and alarm wireing / electronics), and i'm just waiting on the chip

you wouldnt happen to still have your old 85 chip would you capt? or anyone else have a regular EGR delete chip they wouldnt mind parting with?

Thanks,

Ryan

I can still do one for you - I just have no idea when I'd see you to get it to you (I assume you're still transportationaly-challenged?)!
