i been looking everywhere for this and cant find it not even on ebay...is there a specific name of this piece or something?? it seems like a simple common piece but does anyone kno where i can find it?? my local advance auto stores doesnt seem to carry them

in this pic its the black rubber piece the sensor goes into!!

 

try to find a pcv grommet it should work, either in the Help/Dorman section or the hot rod car section of the auto parts store
