Vettech:
Time and Tide Raymond.
If you look down the bottom of the forum page you will see two (2) Users, and 59 guests.
Those 2 users are you and I. Whilst the 59 could be anyone from any place world wide.
And they could be just as easily 59 club members. Not all members come on board and even those who do may only ever look & read.
I'm surprised how many club members I talk to say "yes I read your post - it was good/bad/indifferent) but they never go as far as to comment directly onto the forum - whilst some do get involved and voice their opinions - they are the ones I like best, because they can throw another perspective on an issue.
And your not the only one with limited computer skills, I now, only ever type a sentence or two, because in the past I've typed up an A4 page of technical guff only for my thumb to hit the wrong something and I lose the lot, so I post a sentence then do a "modify" and thus build up the text.
Past issues with heated arguments are no longer an issue, but may have put people off.
I'm happy if I see those numbers like todays at 50 ~ 60 which means we have Corvette Interested people on line. The next time I see you I'll show you how to post up a pic - its not like the ole days with a photo bucket ??? Thingy, as long as your phone takes a pic with the correct acceptable format ie jpeg, etc and under 900kbit it should post up easily.
Regards.

NOW BACK ON SUBJECT.
Sirfixalot - I removed the TB, the manifold side is like the bottom of a coal mine, the water galleries are a mess, the vac ports are full of crap, the pintel on the IAC is an unrecognizable blob of black crud. I thinks the whole assembly is way past a service. Also the seven screws were all different, ones head came off, they are all a rusted mess.
Did you get gasket sets or ??? I'd imagine that place at Eastern Creek would have them, cant remember their name, but surely these are fitted to Holden vehicles. ? I took some pics (with phone) I'll try to post them. (Was Rocket Ind - nothing in Cat)
See! Who said the Pres was good for nuttin. I sent my pic, he returned in different format and smaller size.
Of course no one has been in this TB before, umm of the seven (7) IAC body screws, three were longer Phillips with a drilled out nut as a spacer, three came out correct, whilst one had only the head left.

Glen from Corvette Corner in Victoria has the complete gasket set. I didn't replace the bottom gasket as I am disconnecting water heating.Top gasket under TPI was non existant so there was a potential vacuum leak, Idle control valve washer was non existent sealed with silicon. I bought main gasket from Ponti world same price Glen has complete gasket set.made a new top gasket & a fibre washer from repco 3/4 " hole. Discovered a new problem where the hose tail comes out of front of manifold it goes straight into a bracket for air pump valve have to source a half inch BSP 45 degree male / female elbow. Also need to source small spring clip which holds auto kick down cable onto throttle shaft

Ask Bob, I know the ones you mean, I only removed them this arvo.
Else Phill in Vict or one of those walk around get you own wreckers.

Your throttle body looks worse than mine but you will be surprise what a scratch brush & some turps will do I have a couple of small round nylon pipe cleaner type brushes pushed in every where then flushed with hose.
