I have a 93 T100 with the 3.0L V6 3VZE that's consuming half a quart of oil every 1000 miles with no visible leaks, I want to try some seafoam high mileage in with the oil prior to my next oil change and see if it helps but have heard it can free up deposits that can clog up the oil passageways and cause engine problems, is this a legit concern? Vehicle has 205K and otherwise runs well with no issues.

A quart of oil in 2000 miles is not excessive consumption in a 200.000 mile plus engine.
Leave well enough alone and just check the oil level once in a while.
What weight of oil are you using??

10-30 full synthetic, rec'd weight per owner's manual.
