Throttle Body Plug That Goes No-where And Oil Catch Can Pipe(s) Questions..?

[Peter]

Hi!

Couple of questions....

1. I've just installed a catch can and couldn't get appropriate 15mm piping, so I used 16mm instead (was imperial sizing but converts to approximately 16mm - you can see the red piping in the JPEG "My Engine Bay" attached to this post...). My qestion is how much pressure are the blow-by gasses under? I have tightened the clamps as much as I think they should go, but is it that pressurised that it will still seep out, as it is the wrong sized piping?

2. In the first JPEG (my engine bay) I have circled a plug (grey one), which is attached to the throttle body, but has nothing going into it? I have attached two other engine bays pics, I found within these forums, with second having both a brown and grey plug connected, and the third only having a grey plug (like mine), but it is connected, whereas mine isn't?? What shoud I do? Is this of concern?

Any advice would be much appreciated!

Thanks!

Pete

that is the throttle on off switch. just lets the ecu know when the throttle butterfly is open. what ecu are you running?

The size of piping should be OK and as you have the PCV connected you shouldn't get any build up of blow-by.

You have a series 1 GTS-T do you not? That's why you only have one plug for the throttle on/off switch. The Series 2 GTS-T will have 2 plugs so yours is normal.

the series 1 still has two plugs, they just aren't both apart of the TPS body, one is on a short length of cable coming out the bottom of the TPS.

i'm pretty sure thats only connected on the autos. mine isnt connected either. never has been.

Thanks Everyone,

QWK 32 - At the moment I am running a standard ECU - Series 1.

PSI Parts - thanks for that, one less thing to worry about!

MunkybOy - thanks for that also, I suppose then, in manufacture they link up the auto ones, and leave the manual ones blank like yours and mine...

Thanks for all your help!
