Question about 2001 Jeep Grand Cherokee
I have been doing some reserch on the oil pressure relief valve,on these engines,and i find that in cold weather,lets say -20 c the valve seems to be sticking, first time i have every seen this, i have been a auto mec for years, this problum only started two days ago, and now everything is running fine. assuming that the valve is sticking would you reconmend a engine fush and new oil every 3months,Thank, Paul
I'd suggest using a good brand of synthetic oil (which was actually developed a really long time ago for the armed forces for use in polar reigions) Most flushes loosen too much material all at once, causing blockage of the oil pickup screen. You can get a bit more cleaning and lubrication protection by adding a bit of marvel oil to the synthetic. Change just the filter (and lost oil) about every 1500 miles, till the problem subsides.
