This is an NOS crank case vent hose. This is for the M38A1 and M170 with the 134F four cylinder overhead valve motor. This is the hose that joins the dip stick tube to the elbow on top of the valve cover. It also joins the dipstick tube to the crossover tube, so two are needed for the military 134F motor. This is the real thing and in perfect NOS condition. These were packed in about three or four ways when we got them in. To be fair to all we have removed all the packaging so you will just receive the hose. Most were bulk packed anyway. Hose measurements 1/2″ ID, 3/4″ OD, 6 1/2″ length. Part number 8332675.
