Hi All, I did an in-frame rebuild last year on my Ford 1310. Now just 50 hrs later I have a blown head gasket. I have the manual and followed the procedures and specs, but in review I noticed that as stated in the manual, head bolt torque specs for the 1310 (Shibaura S753 engine) are only 35 ft lbs!! how can this be true?? also noted that the 1300 and the 1500 both need 110-114 ft lbs. 35 ft lbs just seems so low for a diesel engine, could this be a typo? It is stated as 35 ft lbs on both pages 5 and 26 of the official factory manual (which covers models 1100 through 1700).
