Default Is it alright to add vents on the back of the valvecover?

I know you should place the vents on the front of the valvecover because theres a baffle, but my ramhorn manifold is in the way. Will I run into any problems if I tap off the back of the valvecover? Has anyone done it? I plan on running two -10 lines.

If you did, baby jesus would cry.....

just kidding. YEs you can use the back of valvecover, been done many times.

You would have found this out if you searched.

Even the most "famous" catch can, tony1's, uses the front AND back of the valvecover.

You say back side, meaning intake manifold side...I would say thats the best place to place it because the inlet of the baffled part is in front of the valve cover. The end of the baffle is on the factory breathers side. Thats where I placed mine, I had two breathers but I now changed to three. I only have pictures of the two breathers. I'll put some pictures of the three breathers as soon as my valve cover comes back from powder coating.

mine is also off the back... however i had a baffle welded in so no oil would directly be entering the line.... mine is about an inch shorter on each side than the one on the front of the cover
