My 2014 Chrysler Town and Country minivan (110k mi) is making LOUD ticking from the valve train. It sounds like only one cylinder.
I changed the oil with regular Valvoline at the Valvoline quick-lube place about 3000 miles ago. Usually I follow the oil life monitor and it has me change it at about 7000.
The weird thing is that in some cases I start the car cold (it's about 30-40F here) and it's quiet. Then, after it warms up a bit, the ticking starts. That's really strange to me.
This type of engine has a known problem with rockers going bad, causing high valve clearance when they get worn too much. But if the rocker was bad, wouldn't it tick all the time?
I thought maybe one of the lifters was stuck and not "lifting". But if that were the case, why would it be quite upon startup and then get noisy? You would think it would be the opposite. Lots of engines are noisy when they start up but get quiet after they get oil pressure.
Is there anything I could do with the oil? Would it make sense to switch to a synthetic oil, or a thicker oil? It doesn't seem right to switch to a thicker oil in the middle of winter.
