Catch Can Install

Tools Needed

Fuel Safe Hose

     

For my needs the best location to mount was the engine stabilizer rod. If you use the provided bracket you will only need to drill one hole. Cut the bracket aproxementaly .5 inches over one of the holes. This makes the bracket much less noticeable. When drilling your mounting hole, try to keep it low so you will maintain the needed hood clearance.

Configurations

Your personal needs will determine how you route your tubing. If you do not want to truly bypass emissions, but instead only want to prevent so much oil from being burned use method one.

Method 1:

Remove the breather filter from the top and cap it. Now run the crank case hose into the catch can on one side. Using fuel safe hose route a hose from the the other side back to the crankcase ventilation valve. This set up allows the blow by vapor to condense in the can before it enters the intake. While 100% of the oil will not be trapped, it does provide some help while still remaining environmentally friendly.
Pros: Environmentally friendly. Cons: Not as effective as other methods.

Method 2:

Left side of catch can gets routed to the 10mm hose, while the right side gets stepped down to the 6mm hose. Now using a 3/4 inch vacuum cap and pipe clamp close off the 10mm hole in the crankcase valve. Do the same for the 6mm opening.
Pros: The most efficient method. Cons: There is a small possibility for a check engine light.

Method 3:

One side of the catch can gets hooked up to the crank case while the other is plumbed back into the intake via the crank case valve.
Pros: Fairly effective and there is no real chance for the car to see this modification. Cons: There will be a slight leak of unmonitored air into the fuel mixture.
