    Revised timing chain tensioner

    To those that have changed to the newer revised timing chain tensioner.

    Ive read mixed reviews on how to do it. Most say just take the old one out carefully and replace with the new revised version.

    Others say to remove the valvecover and others say its a waste of time.

    Others say to remove the entire timing cover.

    So im trying to find out from people who have done it....whats are we supposed to do with this thing????

    I went through the same thing you are. different ways of doing it. I settled on (long time ago) removing the top to look in and I then pushed in the new upgraded tensioner and while unscrewing the old one I kept some tension on the chain. I screwed the new one in and then used a long screw driver and tapped the tensioner pretty good and it popped out. BUT to be honest before I read anything on it I took the old one out just unscrewed it looked at it and cleaned it and just put it back and started the motor and all was fine. except the tension was not working and I had a bad knocking sound. I then put in the required amount of SEAFOAM in the oil and my boy called me got on the phone and talked for about 10 min away from the 68 ecotec powered Baja Bug. came back and all the knocking sounds were gone and all was nice. Still changed out the tensioner. and have beat the heck out of the motor many times in the desert its on its way back from 100 mile beating today. The engine seem bullet proof.

    I'd recommend pulling the cam cover to make sure the slot lines up. It can be installed extended if you desire not to beat on it.

    Nothing is difficult; some things just take more time.

    From my reading thats not at all normal and is a tell tale sign to change it to the new version asap.

    I went to a u pull it and took off the valve cover on a couple cars and pulled the tensioner to see what would happen.

    On a couple it stayed tight probably because the chain was in better shape but I did have one fall down alot as soon as it was released meaning it would have jumped the timing.

    You can use a screwdriver flatblade and hold the guide taught then screw the tensioner in. Once its close to making or have made contact with the guide you can take the flatblade out.

    I tried it on a car and it made the difference.

    For my own personal car I will be pulling the valve cover since I cannot afford downtime or a bad motor, some say just toss it in but for peace of mind im going to use the screwdriver method to hold the guide.

    It can be done without pulling the cam cover. The key is to make sure the tesioner is "unlocked" and the slot aligns with the guide; pulling the cover makes this process visible as opposed to judging the results upon a feel.

    ^^ WHILE i do agree to a point after seeing the one chain fall of the crank sprocket its not worth it for me.

    I know alot do not pull the cover but it adds maybe a half hr of work and makes it 100%
