I just finished the timing beltjob on my Mk-5 BRM, took my time, had the Metalnerd kit, locked the crankshaft and the camshaft, removed the old one, installed the new one, rotated the crankshaft two revolutions and made sure the locks lined up, buttoned everything back up in about 4 hours. The timing belt kits run between $200 and $300, depending on what you get, I got the complete kit, tensioner, idler, timing belt, water pump with metal impeller, serpentine belt, antifreeze and all the replacement bolts for $269 from ECI Tuning. The old belt looked good, no cracks or tears, but changed it for peace of mind. The original water pump had a plastic impeller, never had a problem and looked fine also. I have replaced timing belts before, and with the locks nothing can move, and the harmonic balancer does not have to be removed. I'm good for another 80,000 miles.
