Interested to see if you notice a difference.

I look at the temperature with my non contact thermometer. down the hole next to the injector . That head mod is a walk n the park to do .
I will wait and see how you get along with it . I am still working on my phantom over heat problem . Still looks like the dash fault . slowly working through the possibilities.....
Squirters are out. I will send them off tomorrow to be reset to factory. God I hope this works...

Gave the front pipe a birthday. Removed the exhaust lag and it was pretty rusted up. Rang Redback to see if I could get a replacement and they don’t make this type of pipe anymore. So I cleaned it up as good as possible, give maybe a gazzilion coats of Exhaust paint then some new lagging.

Picked up my recoéd injectors afterwork today. The crack pressures were all over the shop, ranging from 105bar to 120bar. Now they are all 110bar. Factory spec is 100bar, plus or minus 10bar. So at worst, if it doesn't make a difference to the cooling, it will run better.
Also been doing some research on the thermostat. It seems the factory Nissan stat's by pass valve is too short, needing about 20c above opening temp before the by pass valve will close the system so all water will flow through the radiator. Instead when the by pass is open, water mainly just flows through the motor, rather than going through the radiator, where it should.
So what was done, from what I have read, is to use a longer stat. I have found a Dayco part number listed, so I will order one tomorrow.
Also during my discussions with the chap who done the injectors, he's not confident what we have done will help, but he did also mention maybe fitting an external oil cooler. Which this has been on my mind to do for quite some time, but never really thought much about it.
Keen to get it back together and see what happens.
