Exactly what does the air injection do thats so special on the 99-00 Y8 IM ? as it seems that everyone advertises thermal gaskets for 88-00 Y8 motors but in all reality they do not work right out of the packaging on 99-00 with out plugging up the holes. So what are the advantages to having air injection as opposed to not ? Has anyone else with a 99-00 EX plugged these holes up ?


Just trying to gather some info here.


Thanx

 

It's like a FITV. Let's air pass when the coolant is cold and doesn't when it's hot. That's why it sits in the thermostat housing.

So 10-32 it is.</TD></TR></TABLE>

is that what this is??

 

If it looks like the above pictures thats not the FITV thats the thermostat housing.

 

would u happen to know what that broken thing is in the center? is it related to the "air injection" at all?

Yep, more than likely. Part #24 is it.

 

Mine are full of JB weld and have been for years. I installed a 99-00 y8 mani on a 97 y7 block probably 5 or 6 years ago and nobody seemed to have even heard of the air injection holes causing a problem at that point.

 

yea going backwards is easy my question is what needs to be done to get rid of it while still using the 99-00 IM on y8 that has it as in what needs to be plugged and such.

i would like to know this also....

mine is a stock 99 Y8, only im converting it to obd1. when u plug the holes on the mani, is there anything else u need to do? or is that it? or are there other parts that u can remove?

ill try to take some pix of mine tonight so maybe we can compare...

 

yea im in the same boat converting to obd1 with a p28 - did you break the sensor in that pic ? I broke mine exactly in the same spot trying to get the hose off

well.. that one i dont remember... this motor has been sitting for like 4 years... the hose that was on it, where did it run to?

but i did however break the Knock sensor off the back...

 

from the helms manual

 

i wonder if item #24 (the entire bolt/sensor) can simply be removed, and then just plug the hole on top of that thermostat with a bolt of some sort?







looking at the diagram above... i think if u put a plug on the intake, then remove the FIA control valve (#24) & plug it, then put a plug on the nipple on the manifold.. it might be ok...

especially if ur running obd1...


opinions??

thoughts on this ^^ ?

 

cmon I know someone here knows what to do

 

HELP!

WHat ever happened with this? I have a 00 d16y8 that I need to use a 98 d16y8 intake manifold on. Do I need to plug anything or what??

 

Bump. Would like to know as well.

 

bump again...

I "think" you can plug the holes, port on top of manifold, and remove the FIA control value.

any verification to this?

-platinum

 

Only if u use the 99-00 intake. The only one with holes.
