100% serious and as I noted to sixto, my question could have been clearer.
Pre pcv engines had an up (exhaust) breather and down (intake) breather. Engines now use a PCV and (on a gasser) vacuum to pull fumes from the crankcase - this replaces the old up breather. So to prevent a vacuum from forming in a new engine (certainly not mine w/280K
) there must be some way to let air into the engine - this would replace the old down breather. What is that and do the OM602's have one?
