Can I re-route coolant lines ?

confirmed, the top red circled hole is the egr feed.
block it up, remove the egr valve, replace with a plate.
that top right hole is water. leave the section that goes to the thermostat housing, and delete/seal-up the section that goes to the throttle body.
and there is another bit that goes to the throttle body as well.
loose it!

and dont bother connecting up the plenum heater.
thats the electrical thingy in the bottom of the plenum section (such as it is :x ) below/under the throttle plate.

Don't you mean 'the bottom left hole' as seen from the pictures' view ?

Here is what I'm guessing now, the coolant which flows into that ( ^ ) port, comes up through a little hole into the t/b area and then flows into that hose which comes off the t/b back into the thermostat, so I should be able to shortcut it all and re-direct that hose straight into the thermo housing instead of the manifold side without any problems...correct ?

That plenum heater is yet to stay, I will play around with it once I get some temp sensors hooked up to everything and anything to log and determine its usefullness :)

thats close, but i think the little bit near the up arrow is the hot in so you want to run that to the other inlet on the side if you want to keep the tb heater, if not you run a line from the bottom port on the thermostat to the pipe above the inlet (bottom left hole) then 'T' that off to the cold side of the heater.

Okay scum you've lost me now

Here's a picture of what I mean, (just save, edit in paint, re-save and upload to show me what you mean scum)

Okay, now the coolant hose which goes into bottom red circle, redirect that into a T-piece which fits into the bottom of the Thermo-housing on the Lhs there.

There is a connection coming of the t/b itself which then plugs back into the Thermo-housing, this I believe is the return route/line of the coolant which enters into the port circled in red at the bottom, which I crossed out. That is what Merlin was refering to....... and also to the heater plate which sits at the bottom of the Inlet manifold, not visible in the picture.

The Blue circled thingo, is where the Rocker-cover blow-by outlet/hose plugs into, so I believe.....should this be blocked off aswell as it would have an effect on the AFR mixture into that cylinder right ?

What are the advantages of removing the EGR system btw ?

Awesome tech-drawing skills. Sesame street welcomes you with open arms.

the rocker cover PCV valve goes into the port in the plenum.
you can see it in the pix, just showing between the two head flanges.

Yes that's right Merlin, so what's the 'Fat' hose which come's off the Rocker cover onto the port circled in blue for ?

I thought AB (or someone) said thats the line for the wastegate etc - vac line, or brake booster or something. (The blue one that is).

Yes, as I said before, the blue connection is the vacuum source for the brake booster.

in closing, sorry I didn’t put much effort into making it sound like total BS, I will try harder next time :D
