Knock Sensor

[Skidave]

Hi Everyone,

I drained my block and exhaust this past weekend and installed DIM's quick drain valve set on my Excalibur. I had these on my old ford motor in my previous Nautique and they were quite handy. I also replaced the curved hose from the thermostat housing to the circulating pump with the cast red pipe (along with associated hoses). I don't know why the 03's did not come with them? This was not a fun job...if you want details, I can provide. Anyway, this has a drain plug, which I installed a quick drain valve on too. However, the knock sensor is a pain to remove to drain... Has anyone 1) thought of placing a small brass 'T' between the sensor and the block? This way, you could encorporate a quick drain but still have the knock sensor attached to the block. I'm not sure how sensitive the sensor is and if it would cause problems. In theory, any mechanic 'knock' noise would travel through the small brass piece and be sensed by the sensor. 2) Anyone thought of having a welder tack a fitting to the side of the block so the sensor would fit there and not in the drain plug? Seems a bit extreme, but would save a pain when you want to drain your block.

Thanks,

Dave

RE: Knock Sensor

The knock sensor senses abnormal vibration. Changing the mechanical connection of the knock sensor to the block will change the vibration it gets. How, I do not know. It could vibrate more, or it could vibrate less. Either way, the engine computer will get different data from it. It should also not be overtightened, and thread sealer should not be used on the threads of it. I also found the knock sensor fairly easy to remove, and easier to hang on to when putting it back in. It is much easier to hang on to than a small brass plug.

02 SANTE and mine came off pretty easily too this past week-end. It would be nice to be able to add some type of quick opener to this side though. I had them on my 92 excel and they were very convenient.
