My 2tg cam chain tensioner is leaking oil my last one was also leaking oil (i snapped it trying to fix the oil leak)  I have been told to replcae an O ring for the leak but i suspect it is just the way it is adjusted is the reason for it leaking.
Any suggection or am i on the wrong track,
thanks alot

The timing chain tensioner leaked on my 2TG as well, I just replaced the o-ring (or was there 2 ???) and it never leaked a drop after that.
It cost about $2 or so to fix and took very little time, I think you need some circlip pliers to easily pull apart the tensioner, or you can always improvise.
I remember the o-ring in my tensioner being so hard it was like plastic, I suppose it was 20 or more years old though so no wonder it leaked.
Make sure you use a new crush washer between the tensioner and the head too, or it will leak from there.
If you replace all those things it should be fine.

Yeh i have noticed that if you do it to tight it bog the motor down, haha so ill take my tapper cover of and adjust it so the pressure loaded spring is against the slider and no movement is visible.

I bought some copper washers to put in between the head and the cam chain tensioner, is this what you are talking about when you say crunch washer?
Thanks alot.

It's up to you, if you are pretty sure it was only leaking between the head and tensioner then just the washer will do. If you are unsure then rebuild it with new o-ring.
It is dead simple to rebuild, remove tensioner from head, remove the tensioning nut and lockring. Find the circlip, push in tensioner so that it's not pressed against the circlip, remove circlip. CAREFULLY let out the tensioner (it has a spring behind it so you don't want it to fly out). The moving tensioner part and spring should now come out. You will see the o-ring, remove it and clean all parts thoroughly, fit new o-ring, lightly oil and reassemble it in the reverse order of how you disassembled it. Ensure the circlip is seated properly in its groove!!!
That should be it. Refit and adjust. Just be sure to clean it all well, as a new o-ring on a dirty part won't work.

if you do a search you'll find a link to a site that has instructions about how to rebuild it, i stumbled across it when mine was leaking, but i was stupid and decided it must be the gasket between head and tensioner, i tightened it up a little and SNAP
$182 later i've got a new one in there with the same gasket, and its not leaking a drop

Hey guys just recoed it today worked great doesnt leak a bit, the old washer was plasticy and hard, and used a new aloy washer in between the head.
thought when i pulled it appart it did not have a few of the parts that this one in the picture does, the bits i do not have is that ball bearing and the nylon washer all inside the tensioner.
any ideas why.
the pics are in the link Cool1 provided.
thanks all.
