  Q: What precautions should be taken when disconnecting the battery and performing camshaft and rocker arm repairs for Four-cylinder engines on Volkswagen Rabbit?

  A:

  When it happens that the battery is disconnected, there are a number of systems which need to be relearned before they become functional. There will be severe engine damage in case of mistakes; one should not do this work unless he or she is very experienced in such kind of work. In case of doubt, seek professional advice and recheck all the work to assure that it is all right and only then you can start up the engine. Before installation, the camshafts and lifters must be carefully examined and the endplay of camshaft measured before removal. Even though hydraulic lifters are self-adjusting and do not need any periodical maintenance, in-vehicle check of overly noisy hydraulic lifters is done. With Timing Belt (BPY) engines, un screw the negative battery cable, take off the engine cover and high-pressure fuel pump, the Valve Cover and coolant tube, un screw the camshaft adjustment valve and the vacuum pump, then take off the battery and tray, and then start to work on camshaft removal. In Timing Chain (CCTA, CBFA) engines, the negative battery cable should be disconnected, the vehicle raised, the lower splash shield, engine cover, ignition coils, and spark plugs removed and the engine turned to TDC, then many parts are removed, such as the air charge pipe and the vacuum pump. During inspection, camshaft bearing surfaces are investigated on the damage, oil clearance dimension, and the journal and bearing dimensions of the camshaft runout is also examined, rocker arm rollers and lash adjusters also are investigated on whether they are worn. To install, lubricate and clean camshafts and bearing surfaces then re-fit in normal positions, lubricate the guide frame with sealer and make sure that timing components are well aligned. Once it is installed, do not turn the crankshaft within 30 minutes, but then very carefully rotate it by hand, at least two full revolutions, feeling some resistance and aligning TDC marks.
