Awesome! I have been thinking about doing this for a while now as one of my 420's doesn’t seem to have as much punch as the other. Did you notice any difference on how the car ran after changing the tubes, even if they didnt appear to need changing?

A few questions:

1) Where did you buy the tubes and how much were they? Oh and how many of them are there?

2) If you happen to remember, how many rubber breather tubes are there in total (both small and wide gauge) and where did you get those?

3) did you get new gaskets for the valve covers as well?

4) It sounds like you're a handy guy, how long did it take you to complete the job?

5) Do you know what the torque number is for the valve cover bolts?

6) Now I havent seen what the oiler tubes look like, but how exactly do you change one out? just grab it with needle-nose pliers and pull?

sorry for the million questions

Also, don’t feel bad. While I did know that the air clear just lifts and slides out.....it NEVER occurred to me (until you mentioned it) that I can take it out to change the filters. My busted fingers thank you.
