This DIY tells you how to install a Mishimoto "Compact" baffled 2-port catch can (
http://www.prospeedracing.com.au/produc ... -port.html) on the passenger-side strut tower (RHD vehicles) for the crank case vent / PCV part of the oil breathing system without drilling any holes in your car.
A full-height catch can will not fit in the selected space.

You will need:-
Tools & Sprays- socket sets (mainly 3/8" and 1/4" drive but 1/2"drive can be handy)
- screwdriver set
- allen key set
- multi-grips
- nips / wire-cutters
- sharp knife and/or shears to cut rubber hose
- WD-40 (good for everything, including wetting barbed fittings before putting hoses on)
- assorted clean rags
- work light and/or head lamp.
- throttle body cleaner spray (optional - if cleaning PCV valve & other crusty parts as you go)
- degreaser spray (optional - if giving your intercooler a thorough clean while it's off)
- heatgun (optional, if cleaning the inside of your intercooler with water)
- sandpaper and/or files (to tidy up fabricated bracket)
- spray paint (to tidy up fabricated bracket)
- enough gear out of a "tap & die" set to tap a small thread (optional)
- thread-locking fluid (optional)
- measuring & marking gear
- electric drill & high-speed steel drill bits
- saw & bench vice for cutting bracket to length
Parts- Mishimoto "Compact" baffled 2-port catch can
- at least a metre of 1/2" (12.7mm) inside diameter ("ID") rubber hose - low pressure fuel hose preferred
- about half a metre of 5/8" (16mm) ID rubber hose (heater hose was the best I could get in that size)
- less than 20cm of 3/4" (19mm) ID rubber hose (" ")
- less than 50cm of 3/8" (10mm) ID rubber hose (for drain hose) low pressure fuel hose preferred
- a 9-11cm long x 2cm+ wide, 2mm+ thick piece of alloy or steel to make into a bracket
- 2x M6 bolts (allen-head handy but not essential)
- 2x narrow-diameter bolts that will fit through the Mishimoto bracket holes.
- nuts for the narrow bolts (unless tapping a thread in your bracket)
- 1x 3/4" (19mm) outside diameter ("OD") 90 degree barbed hose-joiner elbow (probably only plastic available)*
- 1x 1/2" (12.7mm) OD 90 degree barbed hose-joiner elbow (probably only plastic available)*
- 2x 3/4" (19mm) to 1/2" (12.7mm) straight barbed hose adapter (brass or plastic)*
- 1x 3/8" NPT thread to 3/8" (10mm) OD barbed (for drain hose)
- 1x 3/8" (10mm) OD barbed-both-ends ball valve (for drain hose)
- 2x hose clamps to fit around the drain hose
- cable ties (various)
[* if you will not be removing the heat shield bracket from the top of your gearbox (discussed below) then you may need more elbows, adapters, joiners, etc. to send hoses around the heat shield bracket]
