Then torque the two 8mm nuts on each side of the camshaft seal (flywheel end) these use either a paper gasket under the washer or an 8mm self sealing nut as used on oil pump cover. Torque these first to 10'# & then to 14'#. Next torque the two center large 12mm studs to 20'# then 24'# and the outer four to 24'# Next torque all the outer 8mm case bolts to10'# and finely 14/15'# using a cress-cross pattern. Rotate the crank, it must turn freely at this time. If not take the case apart and start over as it is most likely one or more of the main bearing pins holes was not properly lined up. Remember that one foot out and one pound pressure is equal to 1'# (one foot lbs) So, 250 foot lbs is the same as 62.5 pounds of pressure 4 feet out from the center of the nut.. ( 250 divided by 4 = 62.5 ) Up or Down ? Any markings on the VW always go UP or FORWARD towards flywheel (front) Several places you will see markings on the VW part will be an arrow on top of the piston. It must point towards the flywheel end of the motor, another is the raised boss cast into the rod beam it will be up on the top side when the rod is installed. Flywheel Gland Nut Torque is critical (to much or to little and the flywheel will come loose). Be sure to follow the torque figures supplied with you new Gland Nut. The stock Gland nut torques to 217 ft lbs HD Chromoly gland nuts torque to 250'# and can be reused. *ck The HD Chromoly gland nut will stand higher torque but the stock crank is the limiting factor and maximum torque should be 250/270'# . Crank info.->*Click Head Torque* and Tightening Sequence on the Head Nuts is very important.->*Click When disassembling a motor with 10mm head studs and no case savers you can check the head studs in the following manner. Loosen each head nut and then torque it to 45/50'#, if it holds then it is ok, if not it needs to be repaired by installing case savers. Then loosen and re-torque to 24'#. Do this to each stud one at a time. If it will not hold the 45/51foot lbs cold it will not hold the 24'# when it's running. It is better to find out now that you need to install case savers then 100 miles later. Cam Gear Backlash should be between .000" to .002" or 0.00 mm / 0.05 mm Oil Capacity Engine Oil = 5.3 pints or 2.5 liters ( Note: 4 qt = 3.785 liters ) Manual Transaxle = 5.35.3 pints or 2.5 liters Fuel (61-79) = 10.6 gal. / 11.1 gal. Add a remote Oil cooler and need to reset the full mark on the dip stick.-> Start the motor and run for several seconds, Then shut it down and check the oil level as soon as the motor stops. It should show up about 1/8" below the full mark if not adjust the amount of oil in the motor until the level shows 1/8" below the full mark then let the motor cool down and make yourself a new full mark for checking when cold.
