My question is- do the OEM tensioners ever need to be bled prior to installing? I've never heard of this being necessary until dealing with this ridiculous NTN tensioner. From what I understand, it's the same tensioner that comes with the Gates "N" kit, which comes with bleeding instructions. Needless to say, I don't trust this tensioner at all & fully plan on replacing it with a Subaru OEM tensioner. Upon doing further research, I've learned that this is a relatively "new" NTN tensioner design, as Subaru holds a patent on their specific tensioner. This pesky oil leak may have just saved my engine!! It was just sitting there, not expanded at all. Grabbed a pin out of my tool box & inserted it through all three holes with zero effort. When looking over the belt to make sure it hadn't encountered any oil directly, I noticed it was VERY loose! Looked at the tensioner & it was fully compressed without the pin. Yesterday, I pulled the timing covers off to investigate a slow, persistent oil leak. ![]() The kit came with no special instructions, so I proceeded with the install as I have on several Subaru's in the past & once everything was lined up & ready to go, pulled the pin on the tensioner. If its not close to the mark, then youll need to determine the position of the valves and try to sync the crank and cams in stages to get them around without a piston pushing on an open valve. I verified the belt was OEM & all pulley were made in Japan before installing. If the crankshaft timing mark is close to the up position, within 45°, you can align the cams up and then move the crankshaft to its mark. A couple months ago, I installed the RCM Timing belt kit.
