Remove engine cover. Remove 4 10mm (8nm) bolts holding on coils and disconnect coils. Remove both breather pipes from cover. undo 3 12mm (12nm) bolts from black bracket near Mivec actuator. Undo 3 12mm (20nm) bolts that bolt mivec actuator bracket to head.No need to unplug actuator, just leave it connected and swivel away from cover. Then remove the cam cover bolts (5.5nm) and lift up the cover squarely. The spark plug tube seals are part of the cover, so DO NOT try to remove these.
When the cover is off, make note of the position of the MIVEC actuator drive for alignment when refitting actuator. there is no reset procedure for this afterwards, it works its own position out. If you do move it by mistake, thats fine, just dont wind it in or out all the way, it might stick.
there is no tightening procedure for the cover bolts, just use the torque figure above.
Thanks again.Just in the corners of the camshaft bearing, and at the joint between block and timing cover, just like the factory put on
Really appreciate your professional advice on this job. I did learn a lot from you. I will take your steps to clean carefully.NO!!!!!!!
Only on inside of cover, but to be honest be careful. I only use mild solvent and water to clean covers i do.
Never try to use degreaser on inside of engine. you will possibly damage seals and thin out engine oil. If it gets in oil pump, pump could run dry. I dont even suggest people using engine flushes. I have seen engines lose oil pressure after flushing
