1988 ford ranger PCV blowby

First off let me say I love this truck. It's a 1988 Ford Ranger 2.9l

6v special edition with roll bar etc. 102,000 miles. I bought it in March and had to within a week replace trans for 1.600.00..and I still love this truck. My question is it appears I have two PCV valves. One coming off passenger side valve cover to air intake which I intend to clean or replace. And one coming off passenger side crankcase up to driver side valve cover into oil fill breather cap. Is the one off the crankcase stock or modification? If it's stock whats it called so I can clean or replace that? I see a lot of oil around the one on the crankcase and I'm leaking oil from valve covers and the oil filter had backed off, so I'm trying to rectify any crankcase ventilation problems and plugged lines. Anyone know the answer to this question? Also anyone use any good internal engine cleaners with success without ruining the engine? And PS I ran a 1991 Ford escort to 152,ooo miles with original exhaust and engine before the trans went and other than two generators , two timing belts and a burnt up third brake light I was very happy with the car. thanks in advance.

One of the lines (the one routed to the intake near the throttle body) includes the PCV valve. It is the "from" line. The gases are sucked from the engines crankcase via this line. The other line (the one routed to the air filter housing area) is the "to" line. It should not include an actual PCV valve. It is the line that provides fresh air to the crankcase. It is not unusual or a problem if you find some oil at the attachment point s for either line.
