Yes, you can do it yourself,Hi, im wonderingwhether i should do this or not. i have a VY series 2 2004, 100,000 km, it has been maintained well and doesnt appear to be leaking however im doing all the hoses and therefore coolant which costs a bit, so im wondering should i be doing this manifold set as well, even though its not leaking? do they all eventually fail or is it lack of maintenance and or earlier models?
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.
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.
