vbrad511 Posted October 17, 2015 Report Share Posted October 17, 2015 I changed oil in the Montero the other night and the plug seal had fallen apart again. I used a metal/rubber seal again. What can I use that wont fall apart every change? Link to comment Share on other sites More sharing options...
