Собрал двиг. Завел. Идут газы в сист. охлаждения. Протягивал так. 3 кгсм
затем 6 кгсм еще раз 6 кгсм и 12 кгсм. Болты старые, до меня могли тянуть и до 20 кгсм может они деформировались или я что то не так делаю? В голове и блоке трещин нет.

недотянул. герметик на резьбу болта №11 положил? отверстие там сквозное, соединяется с рубашкой охлаждения.
процедура протяжки:
1.Remove the shop towels from the cylinder bores. Coat the bores with clean engine oil.
2.Position the engine cylinder head gasket (with the numbers facing up) onto the cylinder block
CAUTION: Engine cylinder head bolts should be reused only once. Replace the head bolts if they were used before or if they have a paint dab on the top of the bolt.
3.With bolt No.14 held in place (tape around bolt), install the engine cylinder head. Remove the tape from bolt No.14.
4.Coat the threads of stud bolt No.11 with Loctite 592 sealant, or equivalent.
5.Tighten the engine cylinder head bolts in sequence according to the following procedure Engine Cylinder Head Bolt Tightening Sequence
CAUTION: During the final tightening sequence, bolt No.11 will be tightened to a lower torque than the rest of the bolts. DO NOT overtighten bolt No.11.
a.Tighten all bolts in sequence (1 through 14) to 30 N·m (22 ft. lbs.) torque.
b.Tighten all bolts in sequence (1 through 14) to 61 N·m (45 ft. lbs.) torque.
c.Check all bolts to verify they are set to 61 N·m (45 ft. lbs.) torque.
d.Tighten bolts (in sequence):
■Bolts 1 through 10 to 149 N·m (110 ft. lbs.) torque.
■Bolt 11 to 13 N·m (100 ft. lbs.) torque.
■Bolts 12 through 14 to 149 N·m (110 ft. lbs.) torque.
e.Check all bolts in sequence to verify the correct torque.
f.If not already done, clean and mark each bolt with a dab of paint after tightening. Should you encounter bolts which were painted in an earlier service operation, replace them.
болты можно использовать только два раза.
