aperseghin Posted October 25, 2010 Share Posted October 25, 2010 So my valve cover is leaking and its time for a change. What else should I do while the cover is off if anything. Other than clean and paint the cover. Link to comment Share on other sites More sharing options...
Carl'sMJ Posted October 25, 2010 Share Posted October 25, 2010 You could look into updating to the newer style valve cover. I believe this is dependent on year of your truck and if it has the H.O 4.0L Link to comment Share on other sites More sharing options...

TrailReadyMJ Posted October 25, 2010 Share Posted October 25, 2010 Explain? Newer style as in from a newer mj or xj? I 88 pioneer I6 aw4 2x4 renix I believe most changed in 92. I know they still used some of the older style covers on 91s even though they had the HO engine. There isn't a big benefit other than an updated oil cap, and improvements in the CCV and breather hose connectors. You will want these hoses as well.
