This head gasket kit, also known as a decarbonizing gasket kit, includes the head gasket with reference 859151, 833070 and is used on MD engines with 89 mm bore. A 1-cyl engine will need one piece, a 2-cyl engine will need two kits, and a 3-cyl engine will need 3 kits. Additionally, this gasket kit includes only one valve stem seal with reference 1306630 and is meant to be used on the intake side. The placement of a valve stem seal on the exhaust side tends to accelerate the buildup of sooting. The cylinder head nuts with reference 994130 and the bolts with reference 970960, 984761, should be replaced when needed[1], and tightening should be performed in two stages, with the second being after the engine has run warm.
Tightening torque settings:
- No1 to No4 110 Nm (80Lbft.)
- No5 to No6 45 Nm (33Lbft.)
Kindly check the second picture that provides the necessary instructions, directly quoted from the Volvo Penta workshop manual.
[1] The cylinder head bolts should be replaced when there are signs of elongation, or cannot be specified if it is already elongated, by checking the "waist" of the bolt.
