1998 Chevy Blazer LS 4.3; I started up the blazer this morning, drove down the road and it start running hot - temp 210 degree, the oil gage reading at 60 psi. I stop and check the oil dip stick and saw that antifreeze was in the oil. The blazer is running ok for now. At this point I feel it can be the manifold head gasket, because there's a broken bolt, What can I do at this time?

 

Not much that you can do but change it and sooner the better . These engines are known for the knock in the bottom end .

 

Thanks

 

You should not drive it because its crazy how fast water will make the bearings go bad .
