does anyone have good instructions on removing the BPV. I want to adjust mine but would like to see some instructions so I know what to expect as well as the time it would take.

 

1) Remove IC. About 5 min. Need a torx screwdriver (25 or 30, don't remember).
2) remove upper hose clamp for the rubber hose between the BPV and intake tracks. This can be a pain, depending on where the clamp head is. I used a big screwdriver, and trashed the clamp. Have a hose clamp or two around to repalce the stock ones. 5-15 min depending on how lucky you are.
3) remove the three nuts that hold the post IC air horn onto the intake manifold.
4) Fight like hell to pull the sucker off, and watch the face of the horn, so it doesn't get scratched. 1-20 min.

There are a lot of variations on 4. If you get replacement bolts for the studs and nuts, you can take two of the studs out with pliers or vicegrips, and the job is much easier. I haven't tried, but this should work, useing some loktite red to glue the nut to the stud, and then back the stud out. A heat gun will soften the lok-tite so you can take them apart later... Then they can be reused.

If you do get the horn out with the studs still in the intake, here's a trick for you....
double nut the studs and back them out (leave one so the gasket doesn't drop when you put it all back togheter).
Using lok-tite blue (softer stuff), but a nut just on the stud to turn it into a bolt. The stuff is strong enought so you can get the stud into the intake, and when the stud bottoms, the nut will brake free and you can torque it down.

First time I did a BPV was a bit less than 2 hours, I went real slow. Now a round trip is about 30 min, maybe less.

obnxs if it takes u only 30 mins, u think u can do a DIY for us? some picciees would be useful to explain this process and some of your tricks! (dubble nuttin).

 

I'll see what I can do... But there are lots of other things on the list as well...
Next time I'm working that far into the motor, I'll snap some photos, but don't wait for me if you've got BPV issues... It may be a long one!

So, if you want to make removing the IC horn easy, you can either turn the studs into bolts, or just trash the studs and get bolts. To extract a stud, you need to double nut (only if you're planning on saving the stud. If you're trashing it just get the vice grips and have at it!). Put both nuts on and tighten them against themselves. They will bind against each other and the threads on the studs.

After you back out the stud, you can put some loc-tite red on to make a bolt, but make sure you place the nut well, as the whole stud isn't threaded.

So, if you want to reuse the studs, taking this horn off is a pain just once. If you switch to bolts, then you can pull at least two of the studs out with the horn still on, and that will make your life easier as well.

Remember, the manifold is Al, so use anti-sieze on whatever you thread into it, if you plan on removing it again!
