Posted on Sep 08, 2008. 4 Answers SOURCE: According to my haynes manual for G-S reg, 1989-1998 it goes as follows, Stage 1:- Tighten all bolts by hand until bolt heads just contact cyl. Stage 2:-Tighten all bolts to 40Nm or 30lb ft. Stage 3:-Angle tighten all bolts a further 60 degrees.
Stage 4:-Angle tighten all bolts again a further 60 degrees. Stage 5:- M12 x 140mm bolts ONLY angle tighten a further 20 degrees. Hope this helps everyone, sorry it seems longwinded but that is how it's written in the manual. Posted on Feb 07, 2009.
BMW cylinder torque setting all models According to my service manual as follows. Cyl head to engine block (torx e12 M10 bolts) Stage 1 30nm (22 ft – lb) Stage 2 + 90 degrees Stage 3 + 90 degrees Cyl head to lower timing chain cover 10nm (89in – lb) The tightening sequence is from inside to outside crossover as normal. Loosening sequence is from outside to inside crossover.
Remember to set torque wrench at low setting and work gradually up through the whole sequence until you get the desired torque. Jun 16, 2008.
Last Updated on Mon, 12 Feb 2018 settings Nm lbf Ignition coil to cylinder head: 4E-FE engine 20 and engines 7 Knock sensor: 4E-FE engine 45 4ZZ-FE engine: Stud 10 Nut 20 3ZZ-FE engine 39 2.3 Carefully prise the plastic shield at the locking tab to release it from the ignition coil 1 General information There are three types of ignition system fitted to models covered by this manual. The first type, fitted to the 1.6 litre, has a fitted to the left-hand end of the cylinder head, which incorporates the ignition pick-up sensors to monitor the position and speed of the camshaft, and therefore the firing cycle. The engine management ECM uses the information from the sensors to calculate the precise moment to interrupt the current to the primary ignition coil, which causes the secondary ignition coil to generate high voltage which passes down the HT lead to the distributor cap. This is then passed to the correct HT lead by the spinning rotor, and then jumps across the spark plug electrodes, causing a spark which ignites the air/fuel mixture.
This type of system, where the ignition coil and igniter is integrated into the distributor, Toyota call their Integrated Ignition Assembly (II A). The second type, fitted to the 1.3 litre 4E-FE engines, is a system. Here the crankshaft speed and position is monitored by a sensor fitted adjacent to the crankshaft pulley at the right-hand end of the engine. The engine management ECM calculates the optimum moment to trigger the spark, then interrupts the primary signal to one of the two ignition coils bolted to the left-hand end of the cylinder head. The positive and negative ends of secondary coils are connected to the spark plugs on cylinders 1 and 4, and 2 and 3. When the primary current is interrupted, the secondary coil generates a spark at the two cylinders it's connected to.
However, only one of these sparks occurs at the correct combustion phase and causes ignition, the other spark occurs harmlessly during the exhaust stroke, and is known as a 'wasted' spark. A knock sensor is also fitted, to monitor for any signs of pre-ignition. Should any be detected, the ECM will gradually retard the ignition timing until the symptoms disappear. The third type, fitted to the 1.4 litre 4ZZ-FE and 1.6 litre 3ZZ-FE engines, has one ignition coil per cylinder, fitted directly above each spark plug. The engine management ECM information from the crankshaft and to calculate the optimum to generate a spark at each cylinder sequentially.

A knock sensor is also fitted, to monitor for any signs of pre-ignition. Should any be detected, the ECM will gradually retard the ignition timing until the symptoms disappear. Precautions When working on the ignition system, take the following precautions: a) Do not keep the ignition switch on for more than 10 seconds if the engine will not start.
B) Always connect a tachometer in accordance with the manufacturer's instructions. Some tachometers may be incompatible with this ignition system. Consult a dealer service department before buying a tachometer for use with this vehicle. C) Never allow the ignition coil terminals to touch earth. Earthing the coil could result in damage to the igniter and/or the ignition coil.
D) Do not disconnect the battery when the engine is running. 2 Ignition coil - testing and renewal Testing 1 Ensure the ignition is turned off.
Engine 2 Undo the screws, and remove the distributor cap (see illustration 3.4). 3 Remove the plastic shield from the coil (see illustration). 4 Remove the mounting bolts from the coil electrical connectors, and connect the ohmmeter leads. 5 Using an ohmmeter: a) Measure the resistance between the positive and negative terminals of the coil (see illustration). Compare your reading with the specified coil primary resistance listed in this Chapter's Specifications.
B) Measure the resistance between the positive terminal and the high tension terminal (see illustration). Compare your reading with the specified coil secondary resistance listed in this Chapter's Specifications. 6 If either of the above tests yield resistance values outside the specified amount, the coil may be defective. 4E-FE engine 7 Note their fitted positions, then disconnect the HT leads from the ignition coils (see illustration).
8 Using an ohmmeter, measure the resistance between the positive and negative HT terminals of each coil (see illustration).
