But the smaller cover mounted on top of the valve cover is the crankcase breather cover. These are prone to leaks. As MAXCICHON stated, it's sealed with a RTV-type sealant. Factory install was inferior. MikeR's DIY post that started this thread is very good. The only issue is which sealant to use. There are several opinions in The Forum. Nearly all of them work. I prefer the Ultra Grey High Torque High Vibration product by Permatex (https://www.crossfireforum.org/forum...tml#post523614). Going on 3 years since I did the repair and no signs of any leaks.

And take the advice from us that the screws needs to be replaced. Originals are aluminum and stretch with the slightest application of torque. That really holds true for any size aluminum screw - 1x use only! If you use aluminum screws, they don't need to be much more than just over "snug". Let the RTV sealant do the sealing. I used corrosion resistant screws (marine grade) and these can be torqued to a reasonable level for the screw size.

And don't get replacement screws from Chrysler. The ones they supply are anodized steel, which is probably okay, but the screws are a couple of mm's longer (due to standard length) and "bottom-out" preventing the crankcase breather cover from attaining a good seal.

Good Luck,
