Pulled the valve cover off of my 2000 4.0 in order to replace a leaking gasket. After thoroughly washing out the cover and allowing it to dry, I noticed a fair amount of what looked like rust on the inside of the cover, mostly above the baffle. That being said, it's not traditional flaky rust, it's more powdery and crumbles away to nothing pretty easily if I put a piece between my fingers.
I did a quick search for possible causes of rust and condensation was the no. 1 thing. This Jeep sits most of the time now, so that makes sense and doesn't really worry me.
Given that this stuff is above the baffle, I can't get to any of it to try and remove it. I'm going to try hitting the inside of the cover with a powerwasher tonight in hopes that the high pressure stream will get up behind the baffle and break some of it loose, but I was wondering if you guys had any other suggestions for removal? I might try soaking it with a little CLR as well.
Or should I drill out the spot welds holding the baffle in place, clean the crud out and then pop rivet the baffle back in with some RTV to seal the rivets? I tend to think that would be more trouble than it's worth...
Thanks.
