Outer Limits 4x4 Board

Just finished putting on my extractors after 4 1/2 hrs. Never thought it would be so much trouble. Had to remove air cond thingy and then when I put the extractors on I could only get 6 out of 8 bolts back in, holes just wouldn't line up. Only out by a fraction of a millimeter but they just wouldn't go in. Will this affect it at all? The extractors are on tight and don't move so I am not sure how they will go. Getting a 2" exhaust on tomorrow.

Started her up and at idle she runs just like normal but when you give it some gas she's far kin loud! It will be interesting driving to the exhaust shop tomorrow morning.

Any one else have dramas fitting extractors? I thought it would be a quick and easy take off and bolt back on again.

I don,t know any one who has fitted extractors/headers would say it was a peicie of pi$$. Yes install all bolts, as the gasket will blow out in no time.
Start with the hardest ones to get to, leave the easy to last, leave all bolts loose until you have them all in. In most cases you have to lever with jimmy bar or phillips screw driver in holes to get them to line up.

If the bolts don't go back in perhaps the holes on the extractors were not drilled in exactly the right spot. Put all bolts in loose before you do them up and see if that helps. If not you will probably have to file the extractor bolt holes a bit.

As said driving without all your bolts in properly will fcuk your gasket.

It was a piece of piss when I installed mine.

no as far as i know dur71 has a 2.2 and by the sounds of it he has got 2.4 extractor they will be fine thou

the ones we fitted to my GQ were piss easy thankfully..
Do it right, or dont do it I say.

Will it affect it? I would say yes, leaking mainfold gasket weekly, remove extractors and file the hole out, will take 0 time per hole...
If the place fitting your zaust is the ones you bought them from, tell them to fix it.

Be thankful you didn't have any head studs break off when removing your old manifold!

I'd just be enlarging the troublesome holes a bit- but make sure you do fit them. Could be wise to pay a bit extra and get a flex section added after the extractors too- should only cost an extra $50 or so but could save the exhaust breaking with engine movement.

how could you break off a head stud removing an exhaust manifold.

It's called rust and has a habit of making old fasteners hard to undo.... I take it you guys haven't fitted extractors to an older vehicle? It's not an uncommon thing to happen. And I'm talking the studs that screw into the head to secure the extractors.

I was told to be extremely careful removing my exhaust manifold as the 2.6litre is renowned for breaking studs during the process.

I had a mechanic break a stud when replacing a manifold gasket on a work VS Commodore.

So it is easy enough to do.

how do head studs rust. aren't they covered in oil. now
exhaust manifold studs on the other hand do rust.

Bored are we?

a little. my tv is in getting repaired.
don't get upset i'm only stirring.

All but 1 of the exhaust studs broke when i did my 60 seriers what a good time i had.

I`ve also found that useing slastic on both surfaces instead of a gasket works best but engine must be completely cold and then not driven for a couple of hours after aswell

something like ultra blue is the go.
