I havent read heard of anyone w/ an m112 w/ a cracked block. Its generally a super-under tuned, all-purpose, torquey motor used from SLKs to MLs, in other words its been pretty durable. My PCV ontop of the valve covers wont stay sealed for more than like 20k, but other than that... the engine's been very durable for me. If I were you, i'd look into the PCV hoses and make sure they're not giving you issues. They may be clogged and can cause some issues there.
On the bright side if yours is giving you issues: m112's are like.. 500 bux now a days and easy to get if you need to pull it out. Pretty sure there is a guy in LA who can swap ya over to an m113 also.
Are you sure your system doesnt have too much fluid in it - Im guessing you've drained it entirely out also.
