Hi,
I understand that the 4.3L engines in the S-10s suck as my 1998 are famous for going through intake gaskets. This can apparently let coolant seep into the oil. Can anyone give me more information on this issue, and if these engines are prone to such problems? I have noted traces of glycol and elevated Na/K levels in oil analyses. How difficult is it to replace these gaskets? Why would an intake gasket allow coolant into the oil? It seems to me that an intake gasket should seal the intake manifold to the intake ports on the engine block/head.
Any info would be really appreicated. Thanks very much,
JMH
