ive built an electronic circuit that interprests signals from a single wire knock sensor which actually works when you tap the sensor with a hard object. it has a LED and a buzzer which screaches when tapped - havent fitted it yet cos the back of the cvh has no spare tappings and it will be near impossible to drill and tap a hole with the motor in.

it has a 10k variable potentionmeter in it to tune it per motor/knock sensor assembly as different size engines have different knock frequencies and each type of single wire knock sensor is suited to an engine size

thinking of fitting an entension block 1/4" bsp female either side of it to fit between the oil sender and the block and half drilling and tapping the side of this block to fit the knock sensor from a toyota 4AGE supercharged motor - anyone ever fitted a knock sensor to a cvh like this?

The efi cvh block has a 8mm tapping at teh back of the block for the knock sensor. That's where I had mine installed when I still had the cvh.
