Okay so I've taken both head covers off and every thing looks good (not smashed, crackled or popped). I took a look at the cam tensioners and noticed that the top piece (see pics) of the front tensioner was free to be pushed in and then spring loaded back to normal. The rear however, was locked up and only after some "persuasion" was I able to get it to move up and down. But it sticks on its way back up like the metal to metal surface has worn a grove that prevents easy sliding. So, I'm trying to remove the chain on the rear side, I've removed the tensioner, but since I can't turn the engine, the second bold holding the cam in is so far inaccessible. Any hints? I was thinking I'll have to take the cylinder off to get to it, but would like to avoid it if possible. Ohh and I took the timing gear off (maybe a mistake, but I wanted to check this) so that I could isolate where the problem was. Since the clutch and transmission were no longer connected to the cylinders I thought if I can spin the clutch basket, while in gear, then the problem isn't in the transmission, and likely in the cylinder heads. Any thoughts? Thanks!
