I finished cleaning my oprv and went out to buy some rosline oil additive like perry suggested. Perry said to drive around for 50 miles and then change the oil. The Rosline container said to add it between oil changes. Has anyone heard anything negative about Rosline in which I shouldn't keep it in any longer than I have to?

I think it will be ok if you change it out after 50 or so miles.
Did cleaning it fix your problem?

I've done it twice, once for loud lifters, once to help oil pressure. Works great.

When I pulled my motor apart, it was clean as a whistle.

I cleaned the OPRV but it still reads no oil pressure at startup. The OPRV looked good, I didn't see any damage to it. I will try to install a new oil filter to see if mine was defective. Can the oil pressure sending unit fail and only register after 10 seconds of running?

Did you try switching the wires on the sender?

Not yet. After adding Rosline, I will take off the connections and clean the terminals. I guess its possible that when I was doing the waterpump I could have moved the wiring and upset it. If is was indeed running without oil for a few seconds I would hear it right? The only noises that I hear are the whine of my belts and the noises from the head which I believe are from the fuel injectors.
