Crancase ventilation delete?

[Draccent]

Why not?

It seems to be nothing but a glorified PCV valve..

Would it do any good? I was thinking it might keep the head and intake manifold completely clean...maybe provide a better mixture since there is nothing but gas and air.

Eliminating that system would compromise the integrity of all your oil seals .

Really no need to do it ....especially on an Eta , leave it alone .

The crankcase vent hose can be changed so as not to route oil vapors from the engine into the intake. This can help on a higher mileage engine where there's more blow-by from worn rings and/or cylinder bores. But it won't help if the cause of the oil is worn valve guides/seals (the usual cause).

If you are going to do this, the connection from the engine needs to be routed into a catch can. And ideally the catch can needs to drain oil back into the sump.
