Sealing the CMP?

[Joe Tracker]

OK SO THE NEW SENSOR , LACKS A SEAL IN THE BOX?

THE SENSOR HAS AND O-RING, IF MISSING THAT MEANS THE SELLER SOLD YOU USED PARTS OR MOLESTED.
its not uncommon for parts over the counter, are from last customer usage, and he stole or lost the oring then returned, it.

its clearly here.

The o-ring on the new sensor is half the thickness of the original. The replacement o-ring also looks cheap. Frankly, the O-Ring in the image of the one from RockAuto also looks cheap and thin - just like the one on my replacement.

I will go back to O'Reilly's and ask for a better o-ring.

Thanks for your help!!!!
