I thought the ratchet part of the tensioner was behind the timing cover, not the nut part itself.After resealing the upper timing cover on the 90 300ce I put the tensioner back in and started the motor for about 4-5 minuites. Noticed the whine from the over tight chain and shut it off.It sounded fine till i gave it a small rev. then the noise. Well found the problem and corrected it.
MY question is do i need to remove the lower cover and replace all the guides and chain itself. from what i can see the guides are not broken. The chain was really tight with that tensioner fully extended.
and yes i do feel really stupid
