is there any need to get some throttle body & plenum gaskets as-well as the intake manifold and thermostat ones? do these need to be pulled apart also?.
Im another victim of the evil oil in the coolant, and am going to have to do this job soon, So ill be using this guide to help me out, Thanks mate!!
It depends on how much of a clean job you want to do. If you want to do it all at once I would suggest this:
- New plenum gasket which sits between the plenum lid and plenum (Rubber seal, costs about $30 genuine)
- New rocker cover gasket (Rubber seal, costs about $19 a side genuine)
- Inlet gasket (rubber seal which sits between the upper manifold/plenum and lower manifold/plenum (Rubber seal, costs about $25 genuine, there was an updated design somewhere between the vs and vx due to slight valley grooves to allow air to flow around or something like that so check with supplier for correct one)
- PVC valve (not sure on cost, includes a spring with it, oil sits in it).
- New injector kits (which include new seals etc to refurbish the injectors)
- New thermostat (reason been, has this ever been replaced on your car? You've probably had a new radiator and numerous coolant flushes, this part prevents ur engine from overheating).
Since you will have all this apart I highly recommend giving the inside of the top of the intake/manifold/plenum a good spray with Carby cleaner to clear up all the black gunk build up. This is a very involved job. Start early in the day and make sure you have the whole day free. Once completed the car should be running smoother and better throttle response. I hope this is the info you were after.
