Yet another oil question 5.3l afm

You might have become very lucky. Keep an eye on on the oil level and drive it.

What kind of miles have you driven since the last top-off? Hwy cruising, or stop & go around town? If the afm hasn't been kicking-in much, your consumption won't be as rapid.

I have a dual Conceptual Polymer PCV catch can setup. The first is the regular CP can and the stage two is the High Efficiency CP can. It is amazing the amount of oil that it separates out of the PCV line. My 2013 has all the new valve cover, deflector, et al stuff that everyone claims that will "cure" the oil problems. I do have the AFM turned off. I have 5000 miles on the current oil and it is still on the full mark. It has never used more than a 1/4 quart in a a complete OLM cycle. Oil in the containers is from roughly 400 miles after last dump. I kept a 16 oz drinking water bottle, totally filled with what the catch can caught in roughly 18,000 miles. That is half a quart of oil.

One can only imagine what this would be doing to the valves and combustion chamber. Is it any wonder some of these engines have major issues.

I have caught a small amount of oil in the couple of hundred miles since I installed my Elite E2 can. I have electronically disabled AFM at 1000 miles and switched to Pennzoil Ultra Synthetic oil at the same time. It should greatly help out coking of the intake valves over the long haul.

Mixed but more highway than the last time so the AFM should have kicked in more not less.

Cowpie...What is the cost of this? The pictures are truly worth a 1000 words. Wow!

Does anyone have the list of things that would need to be bought from the TSB's that have been put out by GM to address this issue?

I want to price out these item's, a catch can and the Range Technology AFM disabler.

Thanks in advance!

A person could, most likely, get pretty good results from using only the Conceptual Polymer high efficiency version. That is all I used up till recently. A friend wanted me to order the regular version for him and then opted out after it came in. I then had both the regular and HE version so I figured I would hook them up in series and see how it worked. I really like the result. The HE version alone is around $130 for the glass version like I have...

The regular version is around $120

Both glass version come with an extra reservoir in case you damage one. If mounted properly, that wouldn't be an issue. Probably only time one would break is if you dropped it while dumping. They are pretty thick glass. These units are not short little air compressor things. My pictures didn't give good perspective, but the units are about 5.5 inches in length for the glass version.

There are many good catch cans, and quite a few that are short of worthless and just separate you from your money. This one I am using is one of the good ones for sure. Probably the cadillac of catch cans is the RX catch can. Not sure it is all that much more effective than what my setup is, but it is not, for me, worth spending any more than I already have to find out. The key to any catch can is the filtration and how the air flow goes thru it.

Thanks for the info...I am going to order the HE version next payday as well as the Range Tech. Module. With what I have researched this should get rid of most of the oil consumption. Then will tackle the rest down the line.
