HELP! I have the 2007 Suburban LTZ with the 5.3 vortec. The oil light came on saying "add engine oil". Dipstick was dry. I thought this was surprising given the truck only had 32K miles on it. The dealer said they found a oil hose leak...and fixed it so I thought.

$3000 miles later....oil light came on again and no oil on the dip stick. They first thought it was the rear gasket seal. I checked my epoxy garage floor and NO OIL---not even a drop on the floor. When I picked up the truck, he said it was the oil pan gasket not the rear engine seal. I thought this funny given I had the mechanic show me the rear seal when it was up on the life--it looked like it was leaking.

Is the oil pan and the rear seal even close to each other?

When I asked how the entire oil supply could be dry without a drop of oil on the floor he said, " It probably blew or burned off as you were driving." I have not noticed any blue smoke from the tail pipe, but I find this hard to believe. I checked the oil level after the last fix and it was filled to the line so I am POSITIVE it was full.

Could it be that GM does not want to pay for a costly warranty repair and the dealer is trying to string this along until I am out of warranty? Truck now has 37,000 miles.

Your engine (power train) warranty is 100,000 miles or 5 yrs, why would the dealer want to string it out?
Not all dealers are out to screw you. Give them a chance to fix it.

The rear seal is on the rear end of the crankshaft and yes it is right next to the oil pan seals.

What he likely mean by burned off as you were driving is, the leaking oil hitting the hot exhaust and burning off. Also, an engine can burn oil and not blow smoke.

I agree, give them a chance. They are fixing what they can SEE. What are the odds of 2 different oil leaks on a 2007?

Just keep an eye on that oil level, document any losses (date, mileage, & amount), & report back to us.

There are dye products that can be added to the engine oil. If there is an engine oil leak somewhere, the leak will be easily detected by special lighting of the dye in the oil, at the bottom of the motor. That would eliminate any leaks as the source of the problem.
If that procedure shows no leakage anywhere, then you might have an internal issue at the piston rings or valve seals to deal with. If the internal leak is minor, you might not see any telltale smoke, especially with single exhaust going through the hot catalytic converter.
Karma is the universal equalizer. The Ignore User feature comes in a close second.

Thanks that is a great help. I am not saying the dealer is trying to screw me but I was frustrated when he said, "the oil breaks down at 3000 miles. You should have gotten it changed sooner". I knew that was BS. When I pointed out the manual said 7500 the conversation got quiet. When have you ever driven a vehicle and run out of oil after 3000 miles!

Other than the steering pump going out at 6000 and the cD player staying on 24/7 and running the battery down it has been a great truck. They have fixed the problems but it took two visits for the CD and two visits for the oil leak.

I think I move service guys within the dealer.

Suburban2007,

Could you please tell me a little more about the cd player running the battery down? I went out to start my truck about a month ago, and the battery was dead after two days of not driving it. I had to find my jumper cables because I figured a 14-month old truck would be fine for a little while longer. I haven't had that problem since then, but would like to know what caused it.

Thanks

I have a 2007 Suburban that looses a quart every 500 miles and getting worse. The dealer is dragging their feet still. I have had enough after 6 attempts to resolve the issue. An oil pressure test was preformed, die in the oil had been placed, valve covers have been off, intake has been off, been told to continue putting on miles, and now the dealer is trying to make it sound like sabbatoge by stating it's my driving, the oil we used, etc. They actually went as far as changing our oil to theirs, marking all plugs, dipstick, etc. We were told once again to drive it an additional 1000 miles, even after I told them I did not want the vehicle back until it was fixed (6 attempt is enough). We brought our vehicle home yesterday only to find the dealer had actually overfilled our oil by 1 qt. Read page 460 of your owners manual and see what over filling does to a suburban. All I have ever done is drive the vehicle and just want to depend on it. Check the web, you are not alone (although my dealer told me I had the only Suburban that has ever done this). You will also find an article titled "Like a knock". All about piston slap in 98-08 motors like ours. Some are inaudible and cause mass oil consumption. Keep a log of EVERYTHING, and make sure you get receipts every time. Check the Magnuson-Moss law. Federal law that will protect you from your vehicle NOT being fixed if they (the dealer) do not help you.

Good luck!

Thank you for your response I have recently completed the first 2 steps according to the book. We are now taking step 3. It is unfortunate the issue was not resolved. I gave them sooo many opportunities to make things right. I just wanted my vehicle to be dependable. The dealer still denies they are responsible for the over fill and also has lied to me about the removal of the intake (just recently discovered). My husband is a 20 year ASE certified technician and he can clearly see the residual dirt is still perfectly intact on the intake around all fittings, all original dirt from day 1. If this were removed, the residual would have been disturbed and/or wiped clean prior to reinstall. We decided to look closer at the intake after all the run around by the service manager. Without looking hard, it was clear no removal was ever done. It is a shame and so frustrating. Especially considering the price of these vehicles. I can't say the issue is caused from piston slap, but there is a DEFINITE problem in the motor. A replacement or tear down should have occurred by now and we could all put this behind us.

Yes, unfortunate. I can think of three individuals that had to pursue this route, both them and I believe the situation would never have gotten to this point if it hadn't been for the dealer (poor customer service).

In fact, as of a few months ago this dealer-------is no longer a GM affiliate. I don't know this for a fact, but rumors are they had so many complaints filed that GM pulled the plug-----that and payments on "some" of the vehicles listed on their floor plan were overdue.

I'd suspect that more than a few these days, fit into the latter explanation.

I do believe these are good rigs, there's 10's of thousands of them running hard every day without any issue whatsoever for them not to be. A few ill-mannered will slip thru the cracks.

If you've lost faith in it, don't trust it, when you end up talking to those on the last leg, I'd try to reach an agreement on a buy out. Hold your ground, I'm sure you're out alot of time and frustration as well. Sit down and write all you can remember, exact details hour by hour if possible and be ready to quote from it.

I wish you the best in your resolution

My 2007 Silverado LTZ 5.3 is burning oil and I'm glad to have found this post, but no resolution was posted. I have been burning about a quart (or more.. low oil light comes on) every 3000 miles, I stepped it all the way up to Mobile 1 synthetic; no improvement. The dealer (Willis in Smyrna DE) took one look and said that they need me to start monitoring it, recording the dipstick and mi at every trip to the gas pump...?! It's losing a qt every 3k miles.. I'm not making this up! No oil in the driveway and no signs under the truck. The tech continued to tell me that even if the results showed 1 qt burnt every 3k, that would be acceptable according to GM!?!? And they wouldn't do anything because GM states that less than 1 qt in 2k mi, is acceptable and would result in more monitoring, and they (the GM dealer, Willis in Smyrna DE) wouldn't be able to do anything. Is this problem common with this motor? Should I be an a-hole and demand to speak with the manager? Any guidance here would be greatly appreciated.
Best,
Rob

1 quart of oil used every 3K is "normal" according to GM. I don't see why GM would buckle on this with just you either- Don't take that the wrong way.

I would recommend you call the toll free 1-800 # in the back of your owners manual & voice your concerns with GM Customer Assistance, then go from there as you see fit.

Document EVERYTHING too.

Good luck....

Would this also pertain to a used 07 or just to original owners. My 07 silverado seems to go thru some oil and it has 64,000 on it.

No matter who the owner is or how many owners, the warranty is on the truck and who owns it makes no difference.

Nothing has to be transferred etc, its time or mileage what ever comes first and as long as you are within those windows, its covered.

Bad Bowtie, thanks for the response. The dealer started the consumption test. (I checked the level right after I got it back and it was a solid 1/8-1/4 inch higher than the full mark on the dipstick). The oil light came on at 2700 miles and I am taking it to the dealer tomorrow. The service desk at the dealer said that there was a Service Bulletin within the "last few weeks" and all they have to do is install a "deflector" to fix the problem.

1) Does anyone know how low the oil has to be for the oil light to come on?
2) Does this sound accurate?
3) Is anyone aware of the TSB?

Even if this fixes the oil consumption, it sounds like a band-aid fix that will probably work just long enough for my drivetrain warranty to run out.

Any advice is appreciated.

Best,
Rob

"cscott97" In reply to your query as to the CD player running down the battery on your '07: This may not be the CD player doing this at all. I have an '07 GMC CC, 5.3 Sierra and at about 12,000 miles it started having the infamous "dead battery" syndrome. The local dealer had it four times and told me they could not find anything wrong with it. I called the selling dealer, 110 miles away and they knew exactly what the problem was. They also called and made arrangements for me to take it to a Chevy dealer just 40 miles away to have this fixed. There were some bad BCM units which would not shut down and would drain the battery. A new BCM, a new battery and all has been well since. Have a dealer check you VIN number for this. There was NO TSB on this.

..back to the oil consumption issue

this '07 5.3L will have AFM.... and it is a known fact that these are prone to high oil consumption... (not every 5.3AFM does this but it is becoming more common all the time... right about at 30,000 miles) ....GM is 'looking into this issue'.. if you bring this to the attention of your dealer he will likely put you on an oil consumption monitoring list.. which means wait because GM does not know what to do about it.... sometimes the dealers will replace all the lifters on warranty, sometimes they will deny that they know anything about the issue/problem.

Some people will tell you that if you turn the AFM off (GM will not do that, you need to get an aftermarket tune or a handheld tuner) then the oil consumption goes away ..... BUT..SO DOES YOUR POWERTRAIN WARRANTY...!!!

I have heard about the proposed deflector 'fix' mentioned in a post above this... but I have not heard that GM is actually doing this yet... it has something to do with keeping the oil away from the cylinders when they are deactivated (ie., when driving and AFM kicks on to deactivated 4 of the cylinders)... I consider this effort to be a band-aid duct tape approach.

I'll never buy a truck with a 5.3AFM engine... I will keep my 5.7L running for a long time yet!!

UPDATE: TSB 10-6-01-008A was completed. Paraphrased on another site by a GM mechanic "GM states that there is a new design oil scraper that is to now be used, to shield the pistons from nearby AFM valve oil splash. To install this special part, the oil pan must be dropped and reinstalled."

I am changing my oil this weekend and will begin my own "oil consumption test" to see if this fixes the problem.

If anyone has had this TSB completed, please let me know how it went. Just a refresher, I have 50K on my 5.3 (with AFM), and the oil light came on after 2700 mi while completing the oil comsumption test for the dealer.

I have a 2007 Suburban (vortec 5.3)with 35k miles. I just had the 1st step of bulletin 10-06-01-008a completed. After completion of work, I was 1 1/2 quarts of oil low after driving 1650 miles. I believe next step is to replace the rings and pistons. However, the dealership that completed the first phase of work with guidance from the bulletin, and did my oil consumption report, just went out of business. I'm really hoping I don't have to start over...especially when it has all been documented!

... good grief! It looks like more and more '07 and newer 5.3L AFM engines are falling right into the oil consumption report lineup! 1 quart in 1000 miles ... hmmmmmh!!!

you'd think your EPA down in the states would start to wonder where this oil is going ... (like into the atmosphere..)

you guys with your '08 and '09 trucks with 5.3AFM better keep reading these posts so you know what you have to do when yours starts consuming oil...

if it were me, I would trade it off quick before GM ends up with parking lots full of these oil consuming things... GM has trucks with a good selection of other engine options that are not AFM!!!!!

"GM has trucks with a good selection of other engine options that are not AFM!!!!!"

Like what, 4.8? V-6?

Everything 5.3 and up is AFM, some with VVT also.

And I'm not so sure that a 4.8 non AFM has enough common parts that it would subject to the same stuff.

For the record, my 5.3 hasn't used a drop yet, 17000+. When this happens, do you go from NO oil consumption to 1 quart/1000 miles?

My 2009 C1500 Sierra has 10K on it's 5.3L now. I has stayed right on the mark between it's two (2) Mobile 1 5W30 synthetic oil changes.

I am starting to get what sounds like the lifter rattle for like 2-3 seconds at start-ups though...

the 6.2L does not have AFM in the new trucks (except for Denali's)

... there is nothing wrong with a non-AFM 4.8L if you are just running a light duty pickup

... and there is also the 2500HD with the non-AFM 6.0 Vortec

... or pick up a good used '06 and older truck with a 5.3L (non-AFM)

Neither of my 5.3 motors (2003 with 125k miles and 2006 with 66k miles) use any oil at all. And I run them 6,000 to 10,000 miles between oil changes on Synthetic.

This has to be related to the newer design of the AFM on these engines. I hope they can figure it out and come up with an easy and free fix for all of y'all with this problem.

.. yes, it seems that the AFM (Active Fuel Management) is the smoking gun (... pun intended..)

.. people with '99 to '06 non-AFM 5.3 engines do not report this kind of oil consumption

I'm still very confused as to how AFM would create this problem.

Can someone educate me?

It seems like all they're doing with the AFM is shutting off spark and fuel...how does that create an oil burning issue?

Thanks much.
