Crankcase breather mod - What did I do wrong??

[getweir'd]

According to other posts about this, the crankcase or whatever utilizes a one way reed valve in the PCV valves that negates the need for a check valve.

thank you for sharing this. i will be removing the pcv valves and replacing them with hose ends that will fasten directly to the valve covers so they will no longer be part of the the system. they will feed to a Y, which will have a one way check valve.

Great idea. Looks like a bit overkill but I like it a lot! :up: :up: :up:


However, those fittings are almost the price of the stock "turret" PCV valves.

Your setup is still hella cool, though.

I can also share my version. I still decided to leave the crankcase exhaust to the air filter, as I know that there is a benefit in this. But I tried to clean them so that there was no oil film and subsequently the intake manifold was not contaminated.
