Vvt Unit Installation.

Great to get the new ones, a complicated and fiddly operation to get them on but all the same worth it. I had scheduled my timing belt to do at the same time, luckily my VVT units hadn't started to leak but were sloppy. the price was fantastic, about 1/2 of what I would have expected to pay from elsewhere , and they were genuine Volvo VVT units too. Got the cam seals as well, they are a must, and you must lock your cams down as well as lock the crank in the most anti-clockwise TDC position for this operation to work. The new hub/VVT Cam adjusting units have no play like the originally installed ones did and in fact I think i noticed an improvement on acceleration now. One note: the factory instructions become bogged down in difficult explanation. I marked my cams wheels (the toothed cogs) in the TDC position relative to a "benchmark:" on the head. I then locked the cams down with the appropriate tool, before I removed the the units I marked on the cam wheels at the opposite extreme position or limit position against the same benchmarks. - I used a 3mm thick steel bar resting on the valve cover bolt heads as a guide (benchmark pointer), using a fine coloured (gold) marker pen I made my markings- both resting and limit positions. The next step was to mark the 3 8mm bolts on the tooth cam wheels by painting the edge of the bolt heads with white marker and let dry. When I cracked these 8mm bolts I left a clear seat position marked on each cam wheel. I then placed my cam wheels on the new units and fitted them with the exact same position as the original. I then sort of followed instructions to a certain degree and turned the entire unit plus cam wheel to the point where they lined up with the benchmarks. Anyone taking on this job must revolve the engine by hand at least 720° of rotation and then back 180° to prime the VVT units with oil or you will get a CEL on the dash. Total job over 3 evenings took 5.5 hours.
