John Paul Posted April 1, 2010 Share Posted April 1, 2010 Hey guys, What would cause my power steering resovor to pressurize? It's not blowing dipstick out, rather seeping out of top. This is on a 2000 427 Vision. thanks. Quote Link to comment https://www.bigmacktrucks.com/topic/13280-power-steering/ Share on other sites More sharing options...

This is on a 2000 427 Vision. thanks.If the P.S. reservoir is overfull for no apparent reason, then the seal on the P.S. pump input shaft is beginning to fail and the pump is sucking in engine oil and pushing it into the power steering system.A telltale sign of this is that the power steering oil will darken as more and more engine oil gets mixed in with it..

John Paul Posted April 2, 2010 Author Share Posted April 2, 2010 Thanks HK, Is this a normal seal replacement, or would the pump need replaced? Quote Link to comment https://www.bigmacktrucks.com/topic/13280-power-steering/#findComment-52391 Share on other sites More sharing options...
HK Trucking Posted April 2, 2010 Share Posted April 2, 2010 You can replace the seal if you wish, but when I encountered that situation, I just replaced the pump with a new one. I reasoned that if the pump was worn enough to need a seal, the rest of it wasn't far behind, and I had to pull the pump anyway, so might as well put in a new one.Also change the filter in the tank while you've got the system drained..
