So the intake gasket

So the intake gaskets took only about 30 minutes to replace and 4 hours cleaning all the carbon, grease and dexcool chunks. Every bolt tread needed cleaning add another hour for that. What a freaken nightmare.

The "crud" on the intake bolts is sealer. After cleaning the threads, make sure you put new sealer on the bolts, then use a torque wrench when tightening them.
