    Default Wrapping up LSA install some last minute plumbing questions (help)

    Like stated in the title wrapping up the install and have some questions on wrapping up the vacuum and evap lines.

    I think I have the evap handled I bought the hard line to go from the solenoid to the line on the firewall. I don't like how the LSA hard line fits so I think I'm just going to use standard rubber hose to clean up the install.

    Big question is what should I do with the breathers on the valve covers and the line coming from the valley cover. I have seen some diagrams with catch cans but and recommendations if I don't have a catch can?

    Thanks

    another dumb question....how many people are still running the plastic impact barrier in the front bumper. I need to mock up the large heat exchanger and all the pictures I can find has the metal guard hacked and no mention of the plastic going back on.....Thoughts?

    I don't have a catch can (yet) but just have the breather lines running as they were before.

    I did not return the crash pad to my bumper.

    As for that black plastic hose connector between the throttle body and the pulley, i have that removed and a plate sealing the hole underneath it.

    My HE is mounted behind the impact bumper. I have no washer tank now.

    Where did you get the hose that connects the brake booster to the front snout

    I don't have the valley cover with the vent but both of my valve cover vents are going to a catch can. I would recommend Mighty Mouse if you want to add one. You really need the vents with the blower. I'd drill out the check valve in the driver's side too so it will be the full diameter of the tube as you'll need all the venting you can get, especially if you are running much boost. I didn't have enough venting early on with a Maggie and the front seal ate a groove in my balancer and it started leaking after a few thousand miles.

    That looks pretty nice, you should get insurance for it though, cause anything self-made has its limitations and possibilities. I'm one of those people that get insurance for anything and everything, I might be paranoid, but it helped me a few times in my life so I'm not going to give up on this habit that I made. It also made me learn some quite useful tricks to finding the best insurer out there. I can recommend some out there if you are interested, especially regarding plumbing insurance coverage cause that's my field of work.
