Am rebuilding the engine on my Porsche 944s 16v and cannot find details of the Cylinder Head Torque settings.
The torque angle tightening method is now valid for all engines of types 924S, 944, 944S and 944 Turbo including all earlier engines from start of 944 production. When making repairs, the following parts must be used:
Cylinder Head Gaskets
Part Number 944 104 374 14 - 924S, 944, 944S Part Number 951 104 374 01 - 944 Turbo only
Cylinder Head Nuts (12 mm high)
Part Number 999 076 028 02 - all types
Part Number 944 104 229 00 - all types
Tightening Specifications to Torque Angle Method
Tightening is done in 3 steps:
Step 1: 20 N-m (15 ft. lbs.) Step 2: 90 degrees (114 turn) Step 3: 90 degrees(1/4 turn)
Sequencing must be kept for each step. Threads and bearing surfaces of nuts must be lightly lubricated with oil prior to installation. Washers must not turn while tightening. Create a reference mark if necessary.
The 12 mm high cylinder head nuts might protrude above the studs slightly on engines produced prior to Feb. 1986. In addition, new head nuts must be used at each repair.
