I am waiting on parts to fix my 88.5 sam head gasket. it had gone soft between the water jacket and cylinder bore on #4 cylinder.
I took the head to a trusted machine shop and it isn't warped or cracked, they think it was just a cheap auto parts store head gasket.
This time I'm getting a full engine set of genuine suzuki gaskets so hopefully this won't happen again.
Mine was due for some work though, it's at 350k miles, replacing all the top gaskets/seals, timing cover/pulleys/belt, new torque camshaft, fuel pump and rocker arm shafts.
I'm glad to see I'm not the only one with this problem. Good luck getting it running again.
