The only solution to the chain tensioners is to do a gear drive cam setup which would mean the cams also would have to be changed to a gear drive cam . The grind on the gear drive is because of the directional change due to the gears. The tensioners have been a problem for some (most) because they follow no particular reason. Some have had them go out at 15K miles while others run them to 60-80 K miles. Usually at about 20K miles, it's time to pull the cam cover and take a look at the tensioners. If you use a small dental mirror, you can get an idea of the back one behind the cam plate and how much is left on it. Only disadvantage to gear drive cams comes with improper gear setup (lash) or excessive run out on the crankshaft that either will make the gear drive noisy. When the tensioners come apart because of excessive wear, the pieces usually score the oil pump and have been known to take out an engine completely and require replacement in the worst case scenario.
