...Jeep claims PCV valve has been replaced every 30,000 as part of regular maintenance. Any ideas?
Jeep claims PCV valve has been replaced every 30k miles?
What do you mean by "Jeep"? A dealer claims there are records in a "Jeep" database documenting the PCV valve changes every 30k miles on your vehicle?
Are you saying the OEM maintenance schedule states to replace the PCV every 30k miles, and you've never done it?
"Jeep" the brand, at Corporate HQ doesn't perform maintenance on individual vehicles, Dealers and independent shops do that. I imagine the centralized service records that Dealers access are done at the Corporate HQ.
A malfunctioning PCV can cause excessive oil consumption.
Someone correct me if I'm wrong, since I don't have a HEMI, but isn't the PCV different then most vehicles? Its NOT an inexpensive replaceable PCV, its a big PCV that is designed to be dissembled and cleaned. If you fail to disassemble and clean it, oil consumption can go up? I think it sorta acts as a catch can for oil as well.
Personally I would NOT trust a Dealer, if they told me they have records saying the previous owners have brought in the vehicle and had the PCV valve replaced every 30k miles. The symptoms are such, that you should suspect the PCV as a possible cause and check it out.
