[VT-VX] VS - VY Series 2 Inlet Manifold Gasket Replacement 6hr+ (Includes Pics)

Yes, you can do it yourself,
Its fairly simple,
The main thing is to do it properly,
Grab yourself some ice-cream containers,
and write on them what parts [ie: Bolts] you are going to put in them. [UIM, LIM, Thermostat, etc etc]
As you dismantle each section, poor some degreaser in all of them that you will use for bolts,
So when you go to re-fit them, all the bolts will be nice and clean after a hose down with water,
Also use some bolt/thread sealant on them,
Remembering to place some dob of sealant at each corners of the front and rear LIM seals,
and most importantly, source a "Tension Wrench", and tension it up correctly, and in the correct sequence ,
as the bolts are not that big, and too much of the crack of the elbow, could snap them off.

Side note:
Not sure if its correct, but I remember a few years ago if this is still done, and read somewhere that depending upon the type of gaskets you wish to use,
Its best to spray a gasket sealent on them [from a spray can].
but I remember we did do it on some engines on the 70's & 80's.

 

That's the problem the spring won't touch the base of the plenum it's 12mm to short..

 

Standard VY 3.8 I guess?

ECOTEC (L36)

 

Thanks again

Yes there sure is mines the 1 with the red blob next to it..

 

All the same components as mine

 

Hi...l must admit ..yr engine is spotless..thanks for the heads up on refitting the gaskets etc...especially the red sealant..

 

Definitely a handy guide.
2nd time having used it and its solid.

Although did it without removing fuel lines (just unmounted them from the plenum section).
For some info, if you do happen to break the pintle cap of an injector (the bright orange cap) you can get replacements from Bursons.
Same as if you break the PCV hose which can be quite brittle over time.
As some components can become fragile over time.
