knock sensor Question

[Houseofperformance]

Hello to the board!

I´m the owner of sy2307 here in Austria. I bought the car 3 month ago with a blown headgasket. While changing the headgasket I noticed that the knock sensor is not mounted where it´s suposed to be. I searched for the hole in the block right next to the oil fitting behind the distributor, but no hole there. Right now the sensor is mounted on a bracket on the last bolt of the lower intake facing downward to the tranny.
I don´t know if the sensor is able to work right in this position. I don´t get any trouble codes and the truck is running strong, but I rather play on the save side. I just got my ultimate v8 along with the FP and FPR from RPM and want everything to work right before I install it. So what do you suggest?
Should I leave the knocksensor in this position or drill a hole in the block to mount it in it´s OG position or just weld a nut on the block an screw it in there?
Is it possible to "test" the sensor if it is in working order?
Please help!
TIA

Joerg

The manual calls for the simple test of tapping the engine lift hook or engine block while monitoring the ECM with a scan tool. I would consider this to only be a "go/no-go" test.

If there is another SyTy owner there, maybe you could arrange a 'side-by-side' test, where you tap in different spots, using lighter and lighter taps until no knock is registered. Perform on both trucks and compare results.

A long time ago there was an argument on the old email list about this, but no quantitative evaluation was done, to my knowledge, comparing sensitivity of knock sensor in various locations.

Thanks for the reply!

I have no scantool yet but I will order the cable, interface and software next week, just to make sure everything is up to par before the chip goes in.
