Hi all,
Just got an idea to write up how I installed my catch can and the fabrication of a sturdy bracket without ANY drilling into the car body.
I have a WH with a 5.7 HEMI but I'm sure it would suit other WH's too.
Well, first, after cleaning out the throttle body and seeing how messy it gets, I though I'll install a catch can to prevent this from constantly happening. So I bought a nice black catch can from eBay for around $20 (Hong Kong) with a little see-through tube that indicates the oil level. I checked again on eBay recently and they didn't have the same types available any more (see photos of it below).
Next step was to install it so it's sturdy but I didn't want to drill any holes into the body of the WH. After a long look around the engine bay, with many different options in mind, I saw a perfect spot. On the side of the coolant reservoir and between the engine, there's an 8mm bolt holding the reservoir down and just above it there's a slotted space left out on the wall of the reservoir. See pic below.
I could already imagine the catch can sitting in there. So I took the bolt out and it was fairly long, perfect for the bracket in mind.
Next thing, I found some galvanised purlins left over from a building site stacked in my yard. See the pic below, the U-shaped one, with a hole in it. That shot was after I chopped a piece of it.
So I chopped of a piece 75mm wide, the width needed to slide in the slot on the wall of the reservoir. Then I chopped off one of the corners, leaving the height of 135mm. That includes the catch can height of 130mm plus the drainage bolt on the bottom of the can which sits next to the reservoir bolt as the can sits on the bolt. So all up 135mm as I didn't want any sharp edges sticking out. See below:
The line just next to the shadow was a slight bend, made by hammer and cold chisel. It was meant to follow the angle of the slot that extends down to the reservoir bolt but later I realised that the can wouldn't sit up straight so I flattened it back and made the bracket go down straight.
More to come...
