TJake and I have been sending messages back and forth to eachother concerning a chirping like noise that we both have coming from the engine compartment, especially de-celeration. He had is belt tensioner & alternator replaced, problem still existed. I had my belt replaced under warranty, problem is still there. His dealer finally figured out that the problem was his PCV valve. The dealer replaced it and the noise is gone! I will replace mine this weekend...I was looking in the guides section on how to replace it and it talks about a new PCV valve...it is known as a "fixed orifice valve" or something like that. Can you buy these at your local Autozone? Should I use this newer updated one even though my motor is not consuming oil? What is the typical time frame to replace this valve? I only have 50,000 on mine, and the part is only a few bucks, so i'll do it anyways...

The PCV valve just pushes into the valve cover and a

hose is connected to the other end. Real easily done

in about 5 min. or less.

 

I have not updated mine yet but plan to shortly.

That new PCV is orificed. Just a small hole. I have had it for a while. I had to get mine at a GM dealership. Was pretty cheap too. Take a look into your intake. If it is oil covered right behind the throttle plate, go get the new PCV! Then clean your TB.

Update: So I just pulled out my PCV valve, and it is the newer version with no moving parts inside. I have a 2002 that I purchased in February of 2002. Interesting, huh? I am trying to stop a chiping like noise that comes from it...maybe i'll try the other kind with the ball inside it and see what that does.

      The Peckish Synapse

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
