Hi guys,

I have bought new fuel injectors for my NL V8. I can see that I need to take off the Throttle Body to get to the injectors already fitted, not too much of a nuisance but is there a gasket that would fit between the throttle body and upper intake manifold? If so, where do you recommend to buy one from? Thanks.

You can leave the throttle body on the upper intake. You actually need to remove the upper intake from the lower intake to do the injectors.

There is a gasket for it that most auto parts shops will have (Upper to Lower manifold Gasket)

As Nigel said, if also recommend using a 3/8 drive 1/2" sockets, with a wobble bar to remove the rear upper manifold bolts.

Cheers guys. Well I contacted Ford who informed me the gasket is obsolete. I called Universal Parts and the only sell the lower intake manifold gasket and so then I called Repco and they only sell the lot in a package which includes the lower intake to throttle body gasket and head to lower intake.

They priced it at $36.99 and it's on order.

I know its a stretch, but Try Race Parts at Yatala in QLD. Theyre Closing but might have some still.

Trick flow and the likes sell indivual gaskets for either the 58mm or 70mm T/B.

Ford racing also do the standard HO manifold gasket and also the GT40 (Explorer).

Hi guys. I ended up buying an intake gasket set from Repco, was only $39. I spent about 4 1/2 hours yesterday, fitted the new injectors, new bosch fusion plugs and k&n filter. The car is completely stock with 223k and by making these changes, f*ck me she drives well.

The only slight hurdle I found was disconnecting the fuel lines, the connectors up the top are strange, and thanks to a few other posts throughout the forum, I just d/c the lines down at the left side of the engine bay and then lifted the whole fuel rail out...

During all this I found the PCV valve hose was not connected to underneath the TB too... and it looked like the TB have been off before and a few connections weren't made including some vacuum lines. Now the TB all torqued up correctly and after a few turns of the key to prime the fuel, she fired straight away with no leaks anywhere. I am absolutely stoked! I just saved myself $2500 in labour lol
The engine no longer has a stutter on acceleration and is much more responsive.

The injectors I bought were VDO (the ones fitted were original Ford).

Now just to replace the alternator (i don't think it's charging the battery properly and its very noisy, sounds like a bearing inside) and to get all discs machined... just the usual wobble at front and squeak squeak at the rear... :)
