Re: Irratic Oil Pressure Problem in CV
Well, I still haven't gotten that oil gauge yet, a friend promised to bring his over this weekend, but he could find it. So looks like I'll need to buy one.
In the mean time my local experts (read: half-drunk moterheads with more big stories than actual knowledge) came over and convinced me to drop some SeaFoam into the crankcase. I did and it started right up like it always does, with the oil pressure reading at the "o" in Normal. After 5 minutes the gauge dropped, all the same as before. Someone suggested I drive it around a bit. Which I wasn't too keen on with the engine tapping and the OP gauge at zero. But I did drive it around a little, nothing too strenuous. The point is, I noticed that when I rev'ed it up, the pressure reading came back up to Normal.
Back in the driveway, I rev'ed the engine up pretty good and goosed it several times. The oil pressure stayed high as long as I had the RPMs up. And the engine sounded fine, no tapping or so little I couldn't hear it over the engine sound. When I returned the RPMs back to idle the gauge dropped and the tapping returned.
I don't know what this means but it must say something to you true experts.
Now should I leave this SeaFoam in the system overnight, or should I follow the directions and drain it as directed (I've seen both ideas explored elsewhere). Thanks for your help!
