I was having a problem with my throttle body sticking. After cleaning it a few times I decided to get the JLT oil separator, It's not a good idea to let oil and fumes go straight into the TB. After several thousand miles I have not had an issue with my throttle body sticking! This is a great product! The only thing that I didn't like is where they say to mount. I modified the mounting bracket to a better location on my 03 Mach 1.
