New Member, I acquired a B7100HST D that I'm pretty sure the head gasket had a leak or the head was cracked. I had white smoke constantly and I couldn't keep it from overheating after 5 to 10 minutes of running. I removed the cylinder head and the head gasket laminated in shreds, some sticking to the head some sticking to the top of the crankcase. I couldn't tell where any leaks may have been happening. I cleaned the head and clamped a plate with a gasket on the bottom (Cylinder side) of the head, I then filled the head with water and let it set for a few days with no apparent leaks, I then machined a plate for over the discharge area and fit an air hose on it to pressure test it, I did get some leaks but, they seemed to be coming from my gasket setup, I had no visible water in the intake or exhaust areas. Concluding I believe that the head is not cracked.
Looking for some confirmation that I have checked this well enough to rebuild.
When I went to clean the head gasket from the top of the crankcase, I noticed a small soft rubber flat ring gasket around the pin pipe (Ref No. 110) that sticks up from the cylinder housing. I'm thinking the was the o-ring Ref No 140 Part Nu 15221-33700. not sure.
Any advice would be appreciated. Thanks
