Any Detroit diesel guys here?

All I did was set the idle speed a tad higher on the hard starting engine. I feel as if it's nothing more than a band-aid for a different issue. As it is, it idles slightly higher than the starboard engine. Oil pressure does read roughly 2-3 psi higher at idle and temp rises to 160 a bit sooner than the other engine. It's been a week without the port side shutting down, and no excess oil consumption or other observable issues.
