Timing chain tensioner oil leak AUIII Wagon

[Cloud Strife]

My Falcon is an AUIII wagon and I am having some trouble finding the correct sized o ring for the timing chain tensioner bolt does anyone know what the o ring specs are ID and OD ?


ApparentlyV890066S and V890156S are the part numbers for the o rings but I have ordered the the oring (V890066S) and the outer diameter is too large.


My Tensioner bolt looks different to those pictured in a few other threads, this is what my tensioner looks like.

This is a picture from another thread notice how my tensioner bolt looks different (no thread on the end that touches the tensioner)

This is what makes me think the o ring is not the right one, when the o ring is located in the valley on the end of the retaining bolt the Outside diameter is too large for it to screw back in with the o ring.


This is my tensioner with the new o ring fitted (V890066S)

And this is a picture of my attempt to insert the tensioner bolt with the (V890066S) o ring fitted outside diameter seems to be too large.
When trying to insert the bolt the o ring wants to slide up the bolt and the the bolt doesn't go in far enough for the thread to bite in when the o ring is fitted.
