header gaskets, help!

[MichelHaak]

hi guys,

i've got a pretty big problem right now. Me car needs to be allright for the yearly car inspection. The header gaskets are very bad and you can clearly hear that they are leaking. I've now put some exhaust kit onto the headers so it's a bit less noise but I don't think the local garage will give the car the green light.
I've got the header gaskets at home but I can't find óne mechanic who wants to change the gaskets because they think it's a bad job to do. Can someone tell me about this job so I know how worse it is to do? I've got airco so that's in the way also I think?

Please help!! :confused:

Depends on what side. Need to know. Is it the passenger side with the a/c? Hopefully not, but most likely will be only because it is a pain in the ass to change.

The driver's side is not bad at all as long as all the bolts are not frozen.

Do you actually have headers, or cast iron exhaust manifolds?

Careful with those bolts, make sure you get a good grip, and hold the wrench straight so you don't ruin the heads of the bolts. Take it slow.

I need to change both sides... I went to the road inspection this morning, the mechanic didnt said anything about the leaking exhaust. :D But the rear brakes didn't work :rooleyes2: so I think the brake cilinders are stuck or something.

But anyhow, can it be done without dismantling the airco etc? By the way I have got the original exhaust manifolds.

Also spray the bolts down with some WD-40 or a good rust removal spray. Like the quote above and do not force the bolts you don't want to break any of them or round off the heads of the bolts.

If you get one that won't move you may have to heat it up. With the air conditioner leave the lines attached but you will have to remove the compressor out of the way, just tie it up keeping it clear.

I would do the drivers side first it's easier with more room to work in.

It may be easier to release the bolts with a hot engine, just be VERY careful to not touch the manifold. Also consider the risk for fire if dropping any inflammable goods there. Thick gloves and long sleeves give good protection.
As the guys already have pointed out, it’s common to break these bolts and it can be a pain to get that little piece left in there out :Blasting:.

In case you don’t feel up to doing it yourself, we could check with Dutch guys on the V8-board in case anyone in your neighbourhood could help you?
