Where and what exactly is an R the timing marks for this engine?

What is your question?

158k on boxer6. I'm doing the water pump and it's more than obvious that someone has been in the timing cover before and even deeper because I can tell by gasket sealer but I am trying to line up the timing marks very unsuccessful I have sprockets with circles that could be timing marks by the teeth and arrows by default I go with the arrows also they're supposed to be colored gold links in the chain that are supposed to lineup with the timing markes. And then I have the exhaust manifold cams that have no arrows just circles and I can't get arrows to line up Circles the lineup nothing the lineup all together at 12 with the cam and the sprockets let alone the gold links in the chain no repair book available for this particular vehicle everyone says referred to the Legacy it is different timing covers different the layouts a little different any info or help would be great

What makes this problem better or worse?

This started as a leaky water pump while I am in here to change the water pump I want to inspect and change if necessary any timing parts engine ran fine before just had a coolant leak at the water pump

How long has your 2006 Subaru B9 Tribeca had this problem?

The coolant link is been for about 2 weeks that I know of
