Lower crankcase sealant

Just a heads up on older Kawasaki water cooled engines.

Have a 26 year old Kawasaki FV731V with fairly low hours however when the factory built this engine they used an RTV that was not friendly to antifreeze. It has just a fair rating in that use and should never be used in contact with coolant as it degrades. True, it took 25 years to do it but that sealant became the only reason to remove the engine to reseal the bottom end.

TB1207B is the sealant class to use. It has excellent resistance to antifreeze (glycol).

All this name calling saying “moron”. There is no Kawasaki FV series engine. Typo or not, no names called, just pointing out this mistake.
 
All I can say is that nothing lasts forever. What is important is the proper application and allowing any sealant to fully cure before putting into operation. This includes the installation of liquids. From there, there are too variables to count every possible one.

The only for sure is death and taxes.
