So I dropped out my 2.7 in order to address 2 major oil leaks. 1 is coming from the 4/5/6 side between the chain case and the cam tower. I'm going to pull off the sprocket to check the camshaft seal. Besides having to recheck timing after this endeavor do I need to go as far as removing all the rocker shafts to inspect. I realize if the seal has been pinched I would need to remove all the rockers to fix and replace. Just want some expert advice on how far I need to go. Also, would this be the only place it could leak is from this red seal that looks to be in place when I look from the side?
Secondly, should the washer on the sprocket be where it is? It almost looks like it should be centered more, but I believe it is a dished washer under the nut so maybe not?
