So here we are a year later, and I'm seeing seepage from the same place as Hermjeji's pic in the earlier post from last year. So, just to be clear, you were able to replace that O-ring at that point without removing the manifold? Seems like the O-ring at that location is recessed into the manifold which would require the manifold to move forward (or the pipe backward) in order to gain access...

It's been a few months since Hermjeji has been on here, but does anyone else have experience with this procedure? Be nice to be able to replace without removing the entire manifold...

just some thoughts...

If it is seeping again then the most common cause it that mating surfaces were not cleaned and polished well enough?...

Or maybe pressure relief cap on the coolant system is allowing the coolant to go more than 15-psi (20psi max) , and it found a weak point?.

Or maybe the components were installed in a way that does not allow for heat expansion of the parts... or in a bind?.
