Default PCV valve location on a 94 SE

Where is the PCV valve on a 94 SE? The service manual says it is under the MAP sensor on the passenger side of the intake. I don't see anything on that side. Or by the throttle body.

Any suggestions?

This is one possibility.

Or in the same area, there may be a plastic cap that is twisted off. If you look very carefully on the cap it will have PCV in small letters on it.

It is on the passenger side of the black plastic UIM under a twisting black 'cap.' You'll have to take your engine cover off to see it (basically same area as the one pictured).

Yes - the black twist cap. I do see that now.

190K miles - I am sure it could use a good cleaning...

Thanks -
