I have been on the hunt for a catch can setup for a few months and nothing has really met the needs of the ej engine and the criteria of the blow by critics.

I finally have found one made by saikoumichi in the US

They sport:

Dual cans to keep the head and crank case pressures separate
Made to order giving the advantage of inlet/outlet size and angle selection
Internally baffled with 3 mesh layers
Super compact design (Large fuel filter size)
Under $200 for both cans delivered
color selection
No unnecessary seals and level indicators

I am currently looking for mounting ideas. I was thinking one on the passenger strut tower for the crank case vent and the other near the air box this would minimise hose length and multiple t pieces

Spot the catch can

No need to "catch" & discard the oil

What does a catch can do that's so important?

Removes blow by oil from the ventilation hoses, which build up in the intercooler and intake, which can also cause knocking.

Take your I/C off, and you will see oil in the there.. This prevents that.

My last motor that had done 130kkms had large amounts of carbon build up on top of the pistons.

I pulled these large chip like flakes from the tops of the pistons and the cylinder head. Definately wouldn't of helped with detonation.

Plus it keeps oil out of your ancillary devices, intercooler, manifold. that can gum up and prevent function.

If you can find a good setup cheap enough like $160 posted^^^^ then it should be on a few todo lists!

whats that red wire running around in your engine bay ?

Isnt the catch can illegal tho due to it directing the oil elsewhere around the engine?



I think its an earthing kit..

Only illegal if they vent to atmo as it increases emissions or something ridiculous. Provided it still recirculates through the intake I thinks it's all ok

Order was put in friday night, on monday they have already fabbed it up and it's ready for shipping.

They sent me this pic to confirm everything was correct:



The idea is the upper collant res will sit inbetween the inlet and outlets, fingers crossed haha.

$170 AUD landed, won't loose any sleep over that

Basically 2 90 degree bends, 1 straight throw and 3 ft of hose

Super stealth ftw

Looks great. might need to invest
