What is this part and why does it matter?
The crankcase breather oil separator removes oil droplets from crankcase gases before they’re recirculated into the intake system, reducing oil consumption and intake fouling.
If you notice any of the following, the part likely needs replacement:
Oil buildup in the intake tract or throttle body
Excessive oil consumption
Rough idle from vacuum leaks caused by a cracked separator
Installation information
Bolts or connects into the crankcase ventilation system — check hose connections for a tight seal after installation.
Frequently asked questions
The separator’s job is to capture oil mist from crankcase gases — when it fails, that oil mist passes straight into the intake and coats the throttle body and intake tract.
Super good! They came through with the part I needed, quickly and at a fair price! Thanks, and I definitely recommend!

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
