Intake Manifold Cover Gasket NEED HELP!

[gautam]

Hey guys, got a quick question. I intend to remove the intake manifold cover and get it re-painted, and I know that when I take it apart I am most likely going to rip up the gasket, so I've been planning ahead and trying to buy a replacement gasket online

BUT

I haven't been able to find a part number or any information online, genuineaudiparts wants me to buy the whole intake manifold because it won't split it apart into a parts diagram, can anyone help me with this? I've looked on ecs, jhm, fcp euro and a few more parts websites I've used in the past. Going to go to an Audi dealership to see if they're parts department can help me out but I thought I'd post about it too.

Just to clarify, I am not talking about the intake manifold gasket, I have those, I am talking about the gasket that goes between the intake manifold cover and the rest of the manifold assembly.

There is no pre-formed gasket there. You have to "make" a new one with a gasket compound, typically silicone RVT. Permatex is popular.

Thanks!

Thanks!

take your time and be careful. i highly doubt you want to pull it a second time due to there being a vacuum leak

there is a picture somewhere that show exactly where the sealant bead should be , I think it comes from the bentley manual . . .

It is pretty obvious once the two halves are apart, there is a groove in the lower half. The worst part is cleaning all the old gunk out.

Do I need the sensor safe high temp rtv or the high temp red rtv? Is it necessary to buy the caulking gun or just squeeze it out of the tube?

Squeezing it out is fine. Black/ grey rtv is perfectly fine for the IM. Be sure to put plenty of the stuff on. IM leaks suck

I guess I don't understand or realize what part you are removing? I am taking my intake manifold off to add spacers and replace the oil check valve kit, will this pertain to me also? good info if it does.

Thanks.

No need to worry about it if you are just doing spacers and the check valve kit. What is being talked about here is that the Intake Manifold actually separates into two halves (upper and lower). The only reason I ever split mine is because I wanted to paint the upper half. I can throw some pics up later if you want.

Yeah that would be great! I am still learning all this stuff. I wanted to change the color of my top, but decided not to as it looks fine now. all paint done by me with high temp ceramic paint.

I used black RTV last year, so far so good!

ahh! I tightened them once, they were hand loose and I was getting all kinds of Bank errors, once i tightened those bolts down, gone were the errors. Thanks for clarifying that.

[Gosser]

One thing to note with installing the spacers, you need to remove your driver side rear engine bracket... otherwise it will interfere with the top half of the manifold, messing up all your RTV.

I got the walk through from ECS for both the spacers and installing the oil check valve kit, I should be good, not removing the top half of the manifold like described above.

Pics would be great!

@Gosser thanks for the info on the engine mount, I'll remove it before putting the intake manifold back on.

Here is the bottom:




Here is the top:




Here is is mostly back together, upside down and backwards :)





And here are two more (after my second paint job a year or two later). The different colors differentiate the two halves. First pic from the from, second is from the back:

Thanks for the pics!! I'll post some pics when I get around to doing the work, need to find a medical cure to laziness first :p
