So Day 1 of it being in the shop. I was nervous to say the least, dropping her off for open-heart surgery lol. On the plus side, again this dealership (Murray GM in Abbotsford, BC) has consistently provided amazing service and no hassles. I mean, its not THIER fault that the AFM engines are burning so much oil. They even provided me with a 2011 Silverado to drive for three days while its being fixed! Fingers crossed. After the piston and rings replacement, has anyone had improvements?? I had my pistons and rings replaced just over 5000 miles ago...I burned 1/2 quart at about 4000 miles..then I changed the oil and I haven't used any in the last 1600 miles..I'm not sure if it just took a few thousand miles for the rings to seat or not. All is good for now...In any case the ring and piston change has made a huge improvement..

Its not the oil...Mine was on Mobil one from the beginning. Its the engine design that is flawed..The mileage on your son's hoe is in the range where these 5.3 start using oil..Keep an eye on it..If you one of the lucky ones you wont see any oil consumption...My buddy has a 07 GMC and his is burning oil as well. I love my truck and I hope now that my pistions and rings are replaced that I'm good to go...Having said that, I won't buy another AFM engine.

"Damage" = Carboned up rings...No magic solution poured into the cylnders will fix it. You have a very valid point though! and you could be right. So for now only time will tell. My dealer tells me that once the pistons and rings are replaced he has seen Zero returns for oil consumption..We'll have to see.. I know I'm keeping a close watch on the Tundras as my next truck.

6000 miles plus...If your truck is using oil and they install the new drivers side valve cover and oil deflector. The damage has already been done and will solve nothing..Once those repairs have been done and then you have the pistons and rings replaced at least for me the problem has been solved.

To the guys going through this Oil consumption deal...I was sceptical as well....After the dealer replaced my pistons and rings along with the oil pan deflector the problem has been fixed. Truck runs like a champ and doesn't use any oil..A good dealer is a must...If your getting the run around find another dealer.

Sounds like its time for new pistons and rings as the damage has already been done.

Time to take it to the dealer and start an oil consumption test..The dealer just installed new pistons and rings in my truck. Don't wait for your warranty to expire...

As note I have just shy of 1000 miles on the new lower end now and have not used a drop of oil..I think the new pistons and rings along with the oil deflector has done the trick.

I would say..Find another dealer...They are all different in how they handle warranty issues....My dealer has been fantastic and has addressed my problems without any grief.

I got my truck back today..New Pistons and rings where installed. The cylinders where honed in the process...The truck runs like a champ. So Now I'm doing another Oil consumption test to see if I burn any oil...I'm keeping my fingers crossed and hope this does the trick..

The New improved valve cover is suppose to help elminate the amount of oil being pulled up into the intake manifold. Thus decreasing oils consumption. I have heard that it works in alot of cases. Keep your fingers crossed.
