DOD Delete - Advice Needed

[ctrow]

I'm looking for advice on what direction I should go. We recently bought a 2007 Yukon with the 5.3L. It currently has 125K miles. I have a oil usage issue and I'm aware of the likelihood it is due to the cylinder deactivation. My question is, should I just have it programmed out or should I do one of the DOD delete kits?

My concern is longevity for the engine, and reliability. It's my wife's vehicle and I don't want her to be stranded with the kid somewhere due to a lifter locking up at some point after just programming it out. We've only had the vehicle for about 3000 miles and already ran through 2 quarts to replenish the lost oil.

If I have to go the route of tearing down the engine to install the DOD delete kit, I'm going to replace the cam as well. I'm wondering if I will be able to clean the pistons/rings with something like Seafoam and letting it soak in before cleaning. I'd just hate to go through that much effort and still have a oil consumption issue.

Any real world experiences are appreciated.

I'm dealer for Diablo sport tuners so I added a intune 2 on my 07 Yukon when was having issues with dod and been 3 months with not one engine code or problem! Before it would throw code every time went into dod mode!

If you want to rebuild the top half of the motor my engine build post has all the DOD removal parts listed. This was a bit over the top for DOD removal but if you read the first post you will see all the parts you will need. http://www.silveradosierra.com/vortec-5-3l-v8/ati-procharger-engine-build-t17320.html

See what motor you have, mine was an LMG series

Range makes a dod delete I had issues with check engine lights I ended up going with a hypertech tuner and just turned off the afm so it stays in 8cyl all the time

Also to be safe I changed the valve cover to the updated one with the pvc that is different

They also recommend changing something down in the oil pan area I don't remember what but it was going to be to much work for me so I did not do it

Happy to report I had a local tuner remove the functionality and I have not had any oil consumption issues since!

Much easier than tearing into the motor. Just hope the damage isn't already done to a lifter that might seize later down the road. If it does such is life. I'll deal with it then.

For interest here are the spark plugs I changed last night.
