lost oil via pcv vent
Hi Guys and others,
Have had my truck for about 2 yrs, 2000 F250 7.3L PSD, never used a drop of oil.(145K Km)
Last weekend, hauled our camper trailer (21FT) up a steep logging road to a fishing lake. Had the automatic transmission in D, transfer case in 4x4 Low. Part way up, noticed the smell of burning oil. Stopped and noted oil coming out the pcv vent. Did not over rev it, and temp gauge was normal. Once we got to a level place, noted that the oil was down to very near the "add" mark, which means I lost almost 2L of oil. I added a liter, and level has stayed the same, not losing oil.
Any ideas what might have happenned, or how to prevent??
