Will be removing them as soon as I can find a replacement set. Truck is still using water

 

Well, as noted above, truck was still using water. When I pulled the valve covers off again, I had the same snotty buildup as last time, only took about a thousand miles to do so.

Swapped out the heads so hopefully that's the end of it.

Can't find any cracks anywhere on the old heads though, but maybe it's just hard to see to the naked eye. But the heads were just gunky, sticky feeling, not the way they should have been at only 94k miles, so something was definitely amiss.

Will update this post as time goes on, maybe it will help someone else out if they are experiencing the same problems.
