Water doesnt flow thru there , exhaust gas does . it cools the exh gas before it gets to the EGR valve .

The race car has the 5MGE EGR Valve cooling water block mounted to the back of the head, and we use it to take the hot water out of the back of the head and back to the water pump. However, every 5MGE I have bought over the years as a spare or to do up as a race engine hasn't had the block on the back of the head - the back of the head is just machined flat and there is a screw in plug where the cooling water outlet hole is to blank it off. Clearly at some stage Toyota did away with the system - but I can't as the engine was only homologated with it. Does anyone have a Cressida or another car with this system still on it - and if so is there a particular year car/engine that I need to look for? Or have I just been really unlucky and bought the only 5 engines in Aust that don't have it?

I don't think any Aus delivered 5MGE has it on there.
All the AUS ones are the gen2 with the smarter ecu.
Import ones may have it, but I've had a couple in the past without the EGR on them.

pretty the only 5M-GE with the EGR are the ones sold in california USA
edit: I think the 5M-E had EGR
For Aus 4M late 5ME and 5MG early also 7MGTE had the EGR
Dave,
Water does flow through there on my car - as I said we use it as a way of getting water out of the back of the head and plumb it back through to where the heater water normally returns; back of the head there is the hottest part of the coolant in the engine I have found and the first area where steam pockets will form. Not interested in its original use, just need a couple more to modify for the next engines. Thanks for the tips, looks like I am trying overseas to find one.

question, its a race engine, why are you using EGR?? my daily 5m-ge has EGR blocked off!!
