I know this seems obvious but, sometimes you just gotta ask. I am replacing the intake gaskets, injector seals (both big and small) and the intake maifold seals(the ones that look like radiator hose).
My question is this. There are 4 throttle body seals attached to the air intake dist., I should replace those as well correct? I told you it was kinda obvious. Do they slide on/off easily or do they have to be cut off and man handled on? I read randy's post about putting on the sleeves flush with the intake and then centering them after installation. Any comments are appreciated.

There are four Intake Runners that go from the Plenum to the intake ports on the cylinder heads. The Intake Runners-to-plenum "outlets" have sleeves which are easy enough to slide on and off once you have broken their surface friction. There is one throttle body seal between the throttle body and the intake plenum.

Colin,
Sorry to confuse you, I am probably not using the correct nomeclature. From looking at Bentley's and my engine there appears to be a round ribbed gasket that goes on the Plenum(?) where the intake runners goes as well. The part number is 022 133 073A. Am I missing something? There is a picture of them on BusDepots site.

UPDATE!
After taking another look at Bentley's and at the air intake dist. and taking ANOTHER look at Benntley's and then scrapping the metal near the air intake sleeves, I realized yet again, I was a moron. Or, in the words of that famous rabbit, "He's such a Maroon!"
What I saw on the exploded fisches was only one gasket, not 4. I havent taken the intake apart yet as I was trying to get all the seals together first. So I didnt realize there were not four other seals other than the air intake sleeves. Colin, I understand your confusion. I am sorry. I am an idiot.
I will go back and hide in my cubicle in shame.

Re: throttle body seal replacement
Update on the vac line repalcment and cautionary note. Finished tonight putting the vacuum lines in and replacing the intake sleeve seals. Replaced the FI seals and put new FI gaskets on too. When I took off my right hand side intake gasket I found alot of old fuel leak residue. Come to find out the tin was lipped over between the head face and the old gasket. That may have been part of the big picture problem with bucking, hesitation, loss of power. I will check the hose routes again tomorrow when it is light out and warmer. Just a reminder to check the tin, that may be a contributor.

Re: throttle body seal replacement
Absolutely but even more, cleanliness, real true deep focused cleanliness. The tins on a Type 4 engine should lay down squarely along the valve cover line.jackstar wrote:Update on the vac line repalcment and cautionary note.
