BE FOREWARNED!

When you go to wiggling the pcv valve out of the valve cover, make sure that the entire grommet is intact. There are 4 outcomes when you pull out the pcv valve...

1. the grommet stays where it is supposed to seat. good

2. the grommet becomes partially unseated. put it back where it needs to be seated. good

3. the grommet pops off along with the pcv valve. pull off and reseat. good

4. the grommet rips in which case the upper part of the grommet stays on the pcv valve and the lower part falls in your valve cover. Dont panic and find a long pair of forceps or anything that can pull something from the hole. Whatever you do dont fish around until it wanders to where it cant be reached. If this ever happens to anyone post back on board. You will only have to remove the valve cover, but its not a big deal. A few poeple have had this happen- myself included and I had no problem getting the grommet out!
