Type of oil or where you live seems to have no difference in this
looked at mine today and still don't have indication of any , never have since day one really
But then moparman says I don't live in a cold enough area, but yet people in NC have it
confused:shrug::happy175::happy175::happy175:
Didnt mean to insult your climate, I am sure your plenty cold there.
Maybe its more based on eliminating short trips, than temperature. When ours was traveling 40 miles a day, we had no build up. Now being it is used on shorter trips and winter weather is here, the build up started. I then noticed a front crankshaft oil leak, that would only occur on weekly freeway trips at 70 mph. Since the crankshaft seal had been replaced once at 60,000 miles under warranty, I couldnt believe it was bad again at 80,000 miles. So I contacted a friend who is a former Chrysler tech, he said before you replace the seal again try this TSB on the PCV system. He then installed it a week later and the truck now has gone 3 months using the same routines, no leak and no yellow buildup.:shrug:
