Has any body had head gasket problems?
Burning anti Freeze
I have worked on lots of these engines but never had head gasket problem.
I am thinking more cracked intake manifold ,rumour is they crack/or gasket.

What do you mean? Is it smoking extremely bad- I had a Komatsu that the propane regulator cracked & was letting coolant into the fuel system. The smoking this created was unbelievable- never saw anything like it. I don't remember what regulator was on it- I know it wasn't an Impco

I agree with you
but this is burning more then compression in coolant.

Had one in a Hyster that turned out to be a bad intake manifold gasket. Check for air in the cooling system- air would indicate a faulty head gasket.
