no not at all. No coolant problems, we even did a leakd own and have good compression...excessive blow by??? the oil cap never whistled...just mayo.
We just set up a catch can to see what is going on. After 200kms of highway driving I had about 3 ounces of water in the catch can. Nobody can say if that is normal or not, but with the catch can I have no mayo from the valve cover tube anymore. The ccv system is still there , I just tagged a catch can at the calve cover in and back to the original return that goes into the ccv.

The question is can a 3.0 produce excessive gases that convert to water droplets? and why is it doing this now...not for last 125000kms??

When these gases turn to droplets, they are supposed to be re-burned off in the valve cover, but it seems to create mayo instead, which blocks the ccv and then regurgitates oil into the intake.

I dunno....what a bad system tho
