Inliners International Forums General Discussion AMC/JEEP Jeep 258 with coolant in the oil

Hello,

I decided to take my pickup on a journey to a family reunion
in Oregon.. I got as far as Anderson, CA. and that's when I
discovered mayonnaise in the oil filler cap..A few days later,
I trailered it back +500 miles home.

Anyone out there experience a cracked cylinder head on a
healthy running Jeep 258 that was NOT, overheating.. I'm guessing it was abused before I freshened it up and installed
it a year ago.. Any info on cracked 258 Jeep heads would be
appreciated.
