MK3 GTI 8V AGG Downpipe & Manifold

[sharki786]

Hi to all.

I wanted to know how easy it is to replace the Manifold & down pipe gaskets on a 8v gti mk3 AGG engine? I need a step by step if anyone dont mind. Beause its blowing from the manifold or downpipe as when you put your foot down abit you can hear it blowing from the engine side so thats the only thing i could think of. Someone who used to work with the mk2's did say to get new copper bolts as they thend to f up after some time and that is causing it to leak??? Could there be any other place to look for leaks?



Cheers girls n boys!

im not to sure if it could happen with mk3 8v but i remember when i had my mk2 i changed the engine and the same thing happened turned out that the bolts were loose just done them up and it was fine , also was told to change a manifold u have to take the engine out not sure how true this is mind u . ive looked at my mk3 and it looks possable to get it out . might be tight tho lol .

oh thats great! cheers pal. took it to my mechanic & he said he dont want to do it as its time consuming & the downpipe is fine! took it to a VW specialist and he said £80 just to change the manifold gaskets  erm i think il have a fiddle! thanks for that, got the copper bolts from gsf (30p each)  , dealers (£1.75 Each) and they had the brass ones shocker! got elring gaskets for the manifold. so going to do it soon!

You can change the manifold with the engine in, but its a bit of a b*stard.

The way I did it was.....

1 Remove the intake pipe between the MAF and the throttle body

2 Remove the throttle body

3 Remove the injectors

The next stage is fun because you cant see any of the nuts for the intake manifold or the heat shield, so you doing it blind! Also there is limited space for tools

4 Remove the Intake manifold heat shield

5 Remove the Intake manifold

6 Disconnect the downpipe from the CAT

7 Remove the exhaust manifold

This is just a brief description, I can try and write a better step by step if you would like. Maybe with pics if your lucky!! lol

There maybe an easier way, but I'm not a mechanic and this seemed to be the only logical way of me removing the exhaust manifold.

I hope this helps

Sorry didnt mean it like that. As im going to be taking the injectors out is there anyway to clean them out? or should i just leave them alone?

its cool dude not to worry bud , um injector cleaning um i would take them to a shop and get them cleaned up m8 or just get some sort of cleaner 4 injectors that can be added 2 your fuel . sorry i cant help much on that dude dont really mess around with injectors . Dave 

[sharki786]

Okies thanks for that. Ive used injector cleaner but not made any dif (i dont think it has). Was thinking if i could diy it cant afford to get them done. Oh and will i be running into problems if i took the injectors out or are they a plug in/out thing and just tighten them?

Thanks all!
