Can you Cross reference Isuzu part number 1-87610006-1?
SAME AS CASE NEW HOLLAND P/N 87327673
According to a Wix filter site, after doing a cross reference check, the LEE LF44HP fits a number of GM cars & trucks from the mid 70s to present, including Isuzu, Hummer and Saab. Go to Wix filters and do a cross product check to find the Wix number. If you use a NAPA filter, the last 4 numbers of the Wix filters are the NAPA part numbers.
If you are haveing trouble setting time on the 3.2 v6 it is because this engine is set on the number two cylender, NOT number one top dead center (as most vehicles are set), Look up at your local Honda or Isuzu dealership and get the Timing Procedure from them. I say Honda Dealership because the Honda pass port uses an Isuzu 3.2 engine.
