Well - compression seems to check out - the HF kit is the 14 piece one http://www.harborfreight.com/14-piece-diesel-compression-tester-set-46800.html
and it does have an adapter that is shaped like a v71 injector - followed BK's advice on WORK FAST (note don't burn the #*&$ out of your arms on the exhaust).
Compression was jumping around 300 - 330 with engine warmish (~160) and at fast idle
but...I found the injector wasnt really seated good - reseated and got a solid 480 - engine was cooling though - thinking cooler engine will get higher compression (is this logical?)
the compression gauge is filled with a thick fluid slowing its descent and letting me get a reading - not as nice as the ones with a "max reading" dial but workable.
I want to test it again as I broke rule 1 - Dont be in a hurry (visiting friends from out of town) and I think I can get the cover off faster now with a 12 point socket (was previously using a wrench - took forever to remove rocker covers).
here is the adapter pic -
So I checked the airboxes - no more parts showing up in there - scoped the cylinder again - still clean
installed new injector and reassembled -
no more smoke and a whole lot more power
hapilly moving down the road to tulsa OK - any busnuts in/around Tulsa?
