mine is leaking, is it possible to just fix like a seal thats under there? without like siliconing it in there? or is the best route just to buy a new one, cause the sensor works perfectly fine it just leaks...also did some research on replacments, and some dont work on certain years? people have problems with the oem units too? just trying to get my ducks in a row here before i need to change the oil.

 

replace the whole thing. the oem units work with every model. it's the off-brand ones that seem to have that issue.
