Ok thanks! I'll take pictures of the whole process because I couldn't find 1 normal tutorial about how to do it step by step.
Hope my motor doesn't blow!
Since this Photo Bucket posting thing I think I will attempt to post my method which is very similar to Fasteddie. One caution is make sure you are careful with the timing chain. My method requires absolutely no movement of the crankshaft after you get the measurements.
Tools that you should have; telescopic swivel magnet( one that you can fix the final angle of the magnet), something to pickup a small watch or hearing aid battery as that is about the size of the shim. A breaker bar, this is used to hold the crankshaft in the exact position. Carbide 200 to 300 grit sand paper.A precision micrometer, best go with digital unless you are familiar using a precision one that measures to 0.0001 mm. A inch pound torque wrench 1/4 inch drive. If you are working on a MK-3 a set of obstruction wrenches / S wrenches for the cam chain tensioner. Feeler gauges Go / No Go , as in the photo.
I removed the buckets and put them in a egg carton, as it was suggested to do one at a time the egg carton wasn't really needed, also I should point out all my measurements were either spec or tight, at 10,000 KM. FYI to the post below
Someone may misunderstand and place assembly grease inside the bucket, this will throw off your measurement when final check. Once assembled there is no movement / wear on the shim. My camshaft lobes had plenty of oil on them and the buckets were removed with a magnet and installed the same way, no oil was removed in the process. Also when reassembly , you are installing the shim , and then lowering the bucket over the shim, using a magnet it is best to keep the magnet near the edge of the bucket, as it could be possible for the shim to be displaced before the bucket is all the way in, from the force of a powerful magnet.
Comment about grease is for building a new motor with no lube, the buckets have oil in them, the cam has a film of oil on it. I will try and post my step by step photos soon!!
