Got it all back together today and fired it up after replacing thermostat, water pump and timing belts. It purred like a kitten. No oil leaks, no water leaks. Video on belt replacement was very good to follow. I noted however in the Honda manual they set the left hand cylinder bank cam pulley on TDC markwhen adjusting the belt tensioner, then rotating the crank another 360 degrees to adjust the right hand tensioner. It seemed much easier to get the right hand tensioner set properly using this method.
As for gasket scraping on the water pump, the video said about two hours to clean them up, I thought that seemed like a lot of time, however once you start in on it, that's about what it took. Got to get them clean, as it's too much work to have to take it all apart again if something starts to leak.
On another note, when I pulled the front cover off, I found the upper left hand 0-ring (when looking from front of motor) pinched and half out of the grove. I'm surprised it still managed to seal the two case halves together. This was how it came from the factory....go figure. I always say it's better to do it yourself, it might take a bit longer, but at least its done right......98 percent of the time.
