Hey guys just wondering what to get before i start this job. im going to be cleaning the TB and plenum.

Carby cleaner
wire brush or tooth brush
TB gasket

What other gaskets and seals do i need? and is it ok to lube the rubbers with a little bit of engine oil?

The Haynes repair manual says the 5 bolts inside the plenum should be tourqed to 15, it dosn't say anything about the 8 hex bolts. As for supplies all you'll need is the throttle body gasket, the rubber seals on the bottom of the plenum can be reused aslong as they are in good condition..

Hi , can the fuel pressure regulater be replaced without removeing the fuel rail ?

all the cleaning can be done using the wynns injector/upper engine cleaner service and it takes about 1/2 an hour.....i charge about $180 to do it at work, great write up tho

thanks for posting them lovely pictures, I was stuffed if I could remember where that damn support bracket that the end of the alternator support bolts too

Just reassembling after fitting new head gaskets to the missus's VT.

She was charged $180 to have the throttle body all cleaned up about 6 months ago, after having it all in bits .. its very apparent that the ripoff mechanic had not even touched it.

Used the throttle body cleaner from Repco, does a nice job, active ingedient is 30% methyl ethyl ketone. use it outside though .. not a good one to breathe.
