I have a 2008 3.3L Sonata bought new which now has seized engine at around 190,000 miles. I had installed all new timing components (chains, tensioners, guides) at around 130,000 miles.

I bought a 113,000 mile salvage engine which I tore down to examine some of the components. With the #1 piston at TDC the timing marks are lined up on the right side as the manual says they should be. The marks on the left exhaust cam however are advanced a bit. Is this normal?

My service manual shows the timing marks on both sides lined up when installing timing chains, etc.

See attached photos.
