Hi SK. The SAFC II was tapped at the ECU side. I pulled the plug on the sensor side on the engine.

WogsRus, the knock will show up in the monitor screen after a peak recall. It works well using my method of determining if it pings. I coud wind in 2 degrees of ignition and it'll ping (ie readings more than 60 over the idle baseline in monitor). Reset the monitor and pull out the 2 degrees, no more ping.

well the highest i have got in the monitor, is 15, that was with the base set to 35 at 1500rpm, all though when showing 15 on monitor, actually 90 on setup.

BUT i don't think mine is right, if it knocked as much as it shows on the setup, engine would be well dead.

PLUS my timming is stock ect.

I wouldn't worry about what it says on setup. It is not an indication of if your motor pings. Only on monitor.

FWIW I had readings at about 120 on setup. It means nothing, its only 'noise'.

      What should I do next to hold the head on

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
