    easy way to collapse tensioner?

    Is there any trick to collapsing a tensioner? I bought a new one, only to have my motor still munch its valves. So I'm transferring it to my new motor and I want to say I've heard its like you can collapse it and quarter turn it and it locks back but I searched and can't find that thread any more.

    Put it in a smooth-jawed vise and carefully collapse it until the circlip catches an internal groove. Go slowly and check often to see if the the clip has caught. You won't get it the first time, but eventually it will stay compressed. No need to turn it.

      I've read advice stating that you should install it expanded so the chain doesn't slap around while the oil pressure builds up, so you may not even need to do that.

        good luck getting it in there expanded. Im curious if anyone has actually done it this way though. compress it, install it, rev it, boom. it really doesnt take long for it to expand when you rev it

          I put a new one in expanded, but not a used one. Does that count?

            I installed the tensioner expanded when I did a timing component refresh. Twas not difficult.

              I installed mine compressed and was all kinds of worried about revving it up to get it to expand. Well, it expanded at about 1100 rpm. Car is SO nice a quiet at start up now :-)

                Uh it's really fucking easy to put it in there expanded, that's how I did, in fact it should be same amount of difficulty putting it in expanded compared to not. You get ridiculous chain slap for about 5 seconds and then oil fills it up.

                  saw no difficulty putting mine in expanded as well

                    I've done both.....it's not that difficult. Just put some pressure on it and turn. Once the first couple threads catch just use a wrench.

                        I've done the install and rev technique before but with the money an time I've put into this new motor I want to do it correctly. I might try to put it in already expanded, I've just heard that it can be too expanded and put pressure on the guide, causing premature wear.

                          I always put mine back in expanded. Even when I had gotten a new one I put it in collapsed like it came but anytime I have to take it out and put it back in I leave it expanded. Never any problems.

                          On a side note, I've tried to collapse it back with a vice and I could never get it to stay collapsed so I never bothered since.
