Narrative:

I was accomplishing a practice ILS approach to runway 22 at mcminnville airport (mmv); oregon in a cessna 152 aircraft. The weather included an overcast layer of clouds from about 2;200 to 3;000 ft MSL. It was clear above and clear below the layer. I was operating on an IFR flight plan and talking with portland approach. During the straight-in approach and about 11 NM prior the runway; I was advised by approach to change advisory frequency (CTAF) and to contact approach again during the planned missed approach. Following the frequency change; I monitored the CTAF for a few miles with the intent of making my initial traffic advisory call just prior to glideslope intercept; which is 5.2 miles prior to the runway. About 7 to 8 miles prior to the runway; I descended below bottom of the overcast layer; into visual weather conditions. About 6 miles prior to the runway; another aircraft made an advisory call indicating they too were on the same ILS approach to runway 22 at mcminnville. Their call indicated they were about 8 miles prior to runway (about 2 miles behind me). I assume the other pilot was making a practice ILS approach in VFR conditions; hopefully operating below the overcast layer. Immediately following their call; I made a traffic advisory call to include my position on the ILS approach. The pilot of the other aircraft asked for my airspeed; to which I replied 99 knots. The pilot declared his intent to pass directly below my aircraft. I continued the approach; visually searching for the other aircraft. In hindsight; I should have executed a climb out along the localizer course. About 4 miles prior to the runway I observed a much faster single-engine low-wing aircraft directly below my nose. The other pilot completed their approach; accomplished a missed approach and departed the area. I never heard any other radio calls from the aircraft. This is the first time I've ever been intentionally passed on an ILS approach.
