Glad to hear it!

I've been looking for info on (what I believe to be) this same problem! I'll be doing this very soon. Thank you for recording all of this, AND for posting the update that it seemed to fix your issue.

Excellent video. I have a 2005 GMC with the 5.3 V8 and the oil consumption/burn is getting worse. I would attempt the process that you showed us but I'm not confident enough to do it right now. I do believe that it would help. Well done!

My 2009 loses some oil and occasionally smokes on start up. Gonna follow your suggestions on my project. Great video!

Thank you for the video. Instructive and interesting.

I finally pulled off the left valve cover on my 2007 5.3L. Mine had that 3/4 inch hole between the 1st. and 2nd. hold down bolts and 2 small slots in the lower center part of the baffle (these are to drain oil from the inside of the baffle I guess). The baffle was riveted tight on the inside of the valve cover. My original plan was to plug up the 3/4 inch hole and dremel a square hole similar to your valve cover. What I ended up doing was enlarging that oil drain hole under the PCV orifice by about 1/2. Hopefully this will allow the oil trapped inside the baffle to drain out faster and not be sucked into the intake manifold. I put the oil level right at the top of the fill mark and check it at 1000K miles.

love your videos!

Labor charges at dealerships are so outrageously high, the only way they can get customers to use them is to design everything so it's a PITA to work on one's self. Thanks for the great video! I hate car dealers and the so called engineers who design today's motor vehicles. A good example is my Dodge Grand Caravan where the upper and lower air intakes must be removed to change the spark plugs. I'd like to meet the moron who designed that mess. The dealerships charge around 3 hours labor to change the plugs. It can be done in less than an 90 minutes if one uses the shortcuts that are posted on you tube.

Since I'm finally getting the time to do this fix myself, I checked your video out! My passenger side is definitely leaking. So I'm doing new valve covers first. And every so often I get blue smoke out the tail pipe. It was suggested to me to try the Moroso oil/air separator catch can (#85481 for the Gen IV engine) in order to stop this occasional oil smoke on startup. That's the route I'm going to take. I really enjoyed the video and it was definitely helpful! Thanks

The oil Lay's agent the gasket, at all times, so it more than likely was leaking, but the grommets probably shrank and hardened too.

Great video and all. But my question, I did an oil change 2 months ago , because I did a flush on my engine since I got a lifter tick. It went away after the 3rd oil change .. but today that I checked my dipstick , it was dryer than a bone. Can that be an issue or why it burned my oil this quick ?

Oil does not “sit” in there and get sucked into the intake. It drains out the whole bottom of that piece inside there. It’s when the pcv valve gets clogged up is when you start getting oil consumption.

@user-ev4pb9xj7e

If that tube ( not a real PVC) gets clogged, how would that make the engine consume oil? Shouldn’t the oil just return to the pan through the oil return passages on each end of the cylinder heads?

They fixed the issue they just can't fix how often you change your oil and quality of oil you use. If engineers were to designe thing perfect I would be out of a job.

Nice job. Passenger side is your fresh air intake for the pcv. FYI most computers have three points ie triangle....car home PC cell phone ect. Sense, decide and act. Ie home PC Sense you press the G key,based on programming Decides you want to see letter G on monitor action displays G on monitor.

Very oversimplified I'm not going over fuel maps,bits,bytes ect.

Are you getting a blueish color smoke out the tail pipe? If so it might be something internal that is causing to burn oil. If not, then I would recommend starting with inspecting for oil leaks. I would try taking the exhaust heat shield off and check thoroughly for leaks around the valve covers and grommets. For the grommets you might need to take the coil rack off to inspect. Hope this helps. Thanks for watching.

1-Original valve cover had the slots. GM's "fix" was a joke. Opening up the hole by the pipe nipple works. Gotta clean the orifice like in this video (passenger side also). 2- I doubt that much oil came from the grommet, but you washed it. 3- What's that AFM sticker on your brake reservoir? Did you have that deleted? If not, amazing it hasn't failed by now.

@@Weekendwarriorworkshop I doubt the year matters. I guess you have a LY5. My experience leads me to believe that when the AMF activates while oil pressure is low (idk below 30 psi) is when the havok starts. Keeping oil changed and eyes on the pressure helps. Not ever overheating or changing oil immediately if it does should help also.
