I cant seem to find the fittings people are running to breathe their valve covers to a catch can. I saw a couple threads in google but not much info.

I plan on running 3 fittings into my valve cover, and I think I'm going to run one line from the back of the block, all into a catch can with a breather on it.


Any pics of fittings, links, and what kind of metal the fittings should be, will be very helpful.

I decided to do 3 fittings on the VC and 1 on the block, because Ive heard breathing the valve cover does relieve crankcase pressure, but it isnt the best, and that the fittings on the back of the block are, so I decided 3 fiittings on the vc, 1 from the block.

I also need to know what size fittings. I don't want them to be too big or too small, so I was thinking -10an fittings.

Thanks

 

Amazing! Tell us MORE!

 

Most people run 12-an lines... Use aluminum weld fittings

And we already established you need to vent the block... And there's a huge thread in this section on catch cans and engine venting...
