Collapsed lifter AFM issue

ndestounis · March 3, 2017

My Silverado 5.3 cre cab was at dealer again for air conditioner issue. I picked it up drove 1/4 mile and all hell broke loose every light light up and it went into safe mode very loud knock started. Drove back and the service manager thought a bad wire or plug.turns out its a colapsed lifter. They are only replacing that lifter nothing else. I would think they would at least do the whole side. Any thoughts or suggestions would be great. Thank you

I had my 2014 Silverado crew cab at dealer again for warranty work. When I drove off I got 1/4 mile and the truck went into safe mode and all the lights went off. I turned around and service manager thought it was a plug wire. Turns out its a colapsed lifter. They will only replace that lifter. Any suggestions please.

Have your dealer read into this document 15-06-01-002E.

Condition
Some customers may comment on a malfunction indicator lamp (MIL) on and/or an engine misfire/tick noise.

Technicians may find DTC P0300 set or in history.
Cause
This may be the result of an active fuel management (AFM) lifter that is mechanically collapsed and/or stuck all of the time.

This may be the result of internal locking pin damage in the lifter, due to oil aeration.

This may be the result of a lifter that has collapsed and is stuck in the lifter bore.
Correction

Note: Inspect the camshaft for damage while the lifters are removed from the engine. If damage is found, replace the camshaft per SI.

If SI diagnosis does not isolate the cause of this concern, technicians should inspect for valve operation.

If the valve(s) are not moving, replace the valve lifter oil manifold and affected bank of AFM lifters. Refer to Valve Lifter Oil Manifold Replacement and Valve Lifter Replacement in SI.

If the lifter has spun the bore, the guides should also be replaced.

RECOMMENDATION/INSTRUCTIONS

There are two approved processes for removing the lifter when stuck in the bore.

Use vice grips with a slide hammer.
NOTE:
Be sure not to pry on the sealing surface of the block.

Use vice grips with a small pry bar.

Typically one of the above approved processes will remove the lifter that is stuck in the bore. If not, the engine will need to be replaced.

With the lifter removed, be sure to inspect the bore for any damage. Typically the lifter bores will look good with no indication of damage.

Service Manager refused to do anything else besides replace the lifter that collapsed. Would not look up bulletin on the issue. Said the warranty would back any other issues. Not sure what else I can do at this point.

Make a copy of the bulletin as provided in the previous posts and show it to the service manager. Ask why he isn't doing what GM states should be done. Escalate issue to dealership General Manager and then to local GM ombudsman (or whatever they are called today). Seems like a known problem with a well-documented solution. Good luck.

Agreed! Take it with you and if that doesn't work go higher

Help new here and...My 2015 Sierra Crew Cab All terrain model has collapsed lifter out of warranty. What do you all recommend? No help from GM complaint line. I’ve only had oil changes done at dealerships and only burn premium gasoline.

Your dealer can perform the work under Goodwill, which may cover part or all of the repair if they value you as a customer. This usually works if you bought the truck at that dealership. Be polite, but firm.

@2017SierraSLT Thank you! Unfortunately we moved across the country and have not established a relationship with this dealership except for a couple oil changes. I’ve called GM complaint and working with them hopefully better news than what this Moran Buick GMC service dept is telling me. $3200 for collapsed lifters and head gaskets.

Don't you still have a warranty?

@Obscenejesster No as I stated in my original post I’m out of warranty. I have 120,000 miles on it. Burn only premium and all oil changes have been done at a GM dealer.
