SpeedFactory Angled Oil Catch Can and Overflow Tank

SpeedFactory Angled Oil Catch Can Coolant Overflow EG EK DC2

Once a boosted B or K series starts making real cylinder pressure, blow-by stops being a footnote. Crankcase pressure pushes oil past seals, coats your intercooler piping, and knocks octane down right when you need it most. This SpeedFactory catch can is the full race-style answer for a 92-00 Civic or 94-01 Integra: a vented breather setup and a coolant overflow tank in one TIG welded unit that drops into the factory battery tray corner of the bay.

What It Is and Why It Works

This is a vented oil catch can, not an inline recirculating one. It replaces the factory PCV system entirely, and crankcase vapors vent to atmosphere through the laser cut logo in the breather plate after the baffling knocks the oil and moisture out of suspension. For forced induction and heavily built NA engines, that means crankcase pressure has somewhere to go under sustained load instead of pushing past your rings and seals. Four -10AN weld fittings, two upper and two lower on the left side, give you real breather line capacity from both valve cover and block, which is the flow a high-output engine actually needs rather than a single skinny hose.

The angled body with integrated coolant overflow is the packaging trick. It occupies the factory battery and fuse box location, replaces the plastic factory overflow bottle, and consolidates two containers into one corner of the bay. The can is CAD designed, CNC press punched, and TIG welded including all the billet fittings, with a billet removable SpeedFactory coolant reservoir cap up top and an aluminum mounting bracket already attached.

What's Included and Specs

Fitment

This is the left-hand drive version. If your EG, EK, or DC is right-hand drive, SpeedFactory makes a dedicated RHD version with the ports mirrored for that layout, so make sure you grab the right one. Engine-wise the can doesn't care what's in the bay, B series, K swap, D, or H, as long as you plumb the breather lines to match your setup.

What to Know Before You Buy

Plan the whole install before you click buy, because this can takes over the battery and fuse box real estate. That means relocating your battery, whether that's a small battery elsewhere in the bay or a trunk-mount kit, and finding the fuse box a new home. On a race car or a serious street build that's usually already done or on the list. On a mostly stock car, that's the project this part is part of, not a bolt-on afternoon.

Two more honest notes. First, hoses and the mating AN fittings aren't included, and SpeedFactory makes hose and fitting kits for these cans that are worth ordering at the same time so the car isn't on stands waiting for lines. Second, this is a vent-to-atmosphere setup that deletes the PCV system, which is a race and off-road configuration. Your engine bay will smell like a race car because it's breathing like one. If you want a street-manners setup that keeps PCV intact, a sealed inline catch can is the better tool, and this one is for the builds that have outgrown that.
