Oxygen Sensor Gasket

V12-Engine

Have looked at my parts CD but it does not show the oxygen sensors. Is there suppose to be a crush gasket or not? Thanks

Don, I am pretty sure every O2 sensor I have fitted has had a copper crush washer “pre-fitted” onto the sensor??? I have just ordered another one for a vehicle and the picture looks like there is a crush washer on the body under the nut?

The following image is not necessarily a Jag sensor, but all have a crush washer seal fitted under the nut …

Cheers
Mark

No auto parts store locally carry the oxygen sensor crushable gaskets. Found them on E-bay. Due to arrive on March 13, and will let you know if they fir. They are AC Delco 18mm part number G18mm. Cost about $5.50 each with free shipping.
