lots of funky things
Yeah, there is a lot of funky things about this engine, but it certainly has a grommetted hole in each valve cover! There are two filtered plastic fittings into the air cleaner, as is often used with PCV's, but the diagram for this car doesn't show them, nor does it show anything fitting to the air cleaner.
Ah well, I'll just skip that for a bit, unless you have pics? Next we need to get the oil and filter changed, and then check out why it is revving so high at idle.
