Which line to tap for catch can install on the Hybrid engine?

[wax87]

My understanding catch cans are for Direct Injection engines. NOT port injected. The difference being port injection injects fuel into the port before the intake valve so it cleans the oil from the PCV system off the valve. Where Direct Injection the fuel is injected into the combustion chamber there for NO fuel to clean off intake valve that comes from the PCV system. No idea why some claim turbo has any play in this. Turbo on the intake side just has pressurized air . Pressure increases heat so maybe the oil from PCV system is more prone to get burnt onto intake valve? Either way its all about Direct Injection verse Port Injection. Say a turbo engine had port injection then I would say no catch can needed. Yes yes I know the 2.0 Ecoboost is both turbo and direct injection but the need for catch can is related to the fact its Direct Injection not turbo charged.

Since Hybrid is port injected DON'T do it your wasting your time.

Perfectly said!

My experience with small high performance turbo engines and crank case breather catch cans is small high performance turbo engines puke a lot of oil; and yea the DI thing too.

There's no reason to do it on your hybrid, and MANY reasons not to do it. Just say no to wasting time and money.

No need, like they said, not a direct injection engine. Just add 4-6 ounces of Lucas fuel injector cleaner every few tanks. That is all you need. (Or your favorite brand). There is no positive pressure in this intake system like a turbo.

The Hybrid has a port injected engine. Fuel mist is constantly washing the intake valves when the engine is running.

This!
Carbon buildup on the valves is minimal on port injection engines... particularly Atkinson cycle engines.
