ok so what hose runs to the nipple under the TB?  at the moment i have nothing running to  that nipple and as a matter of fact there was never anything conected to it...

ICV > TB
or
ICV to Intake Elbow

I thought the large hose underneath came from the AFM.

Awesome thread gents.

I'm in the process of installing some Ford Explorer 19lb 4-pintile injectors now on my E30 318iS and I forgot to order all of this stuff to clean up all the mess under the intake manifold.

I'm ditching the throttle body heater plate, its pretty ridiculous cooling system that runs through there!  Only one of my hose ends is split so will put it all back together using all the old parts cos I need the car back on the road ASAP as it's my daily driver.

Will order a fresh set of hoses and such when my E36 is back on the road!.

Is it necessary to order both intake gaskets, the upper and the lower, to do this heater plate and hose delete if I'm not going to do my injectors also? I've never had my intake off and I drive it daily so I am making sure I get my parts order square before I do the project. I've read the entire thread but I'm not sure I need to take off the lower intake if I'm not going to do my fuel injectors.

Update: Upon further reading I see that the plastic coolant pipe is inaccessible without removing the lower section of the intake. Question redacted.

Quick one for the group. I have completed my own "delete" and am putting it back together. However, I also replaced all the heater hoses going into the firewall. I saw another thread where the auxillary thermostat was simply deleted and I did the same but before I put everything back together again, I wanted to ask if this is a good idea or if I should cut the new hoses and splice in the aux. thermostat. It seems it was installed after the fact for a recall, so I think it will work fine without it, but just thought I would ask. Thanks.

Just figured I'd add my own $.02

A buddy and I just did this mess under the intake fix on my car the other day.  The car hasn't run this good in a long time. I knew I had a misfire somewhere as the car wouldn't idle properly and was throwning a check engine light but only at idle.  I then started seeing coolant along the bottom of the block.  also eventually heard a loud hissing noise and the car wouldn't stay running unless it was fired up 2-3 times.

Every single hose under there was split at the ends, the coolant pipe was cracked and the coolant hose at the back of the block which routes to the heater pipes was split and dumping coolant.  I removed the TB Heater like we've all talked about and it runs like a dream.

Rich Dixon - I bought the exact parts list from Post #1 and I had everything I needed... I bought my parts from Pelican.  The O-Ring I have is extra as the plastic coolant pipe came with an O-Ring on it. Also, the fuel hose, you only need about 6 inches total to replace the two short lines that route through the lower intake.

Great writeups here, I'm very pleased with how it all turned out!

Under the rubber elbow between the air meter to the throttle body where the crankcase ventilation normally ends.

I am having trouble understanding this. Is your path the same as this:





I think you're saying your valve cover goes to the air intake accordion and your ICV goes to the nipple under the throttle body, which would be different from these pics.
Also, can you clarify for me what size vacuum hose you're running from the valve cover and from the ICV?

Can someone re host the original post's images? I pulled my intake manifold off, and there is no way its getting back on the way the hoses are. And I figured now would be a great time to take care of all the stuff under there that is not needed. Thanks!

And I am in wisconsin, and the car would probably outside in the winter. Would deleting the heater plate be a poor move?

No. Do it, you will not regret it. Car has no issues in sub-zero weather in Janesville. Did mine last year.

Does anyone have the missing pics from the first post?  I'd be happy to throw 'em up on Flickr or something…
