Great videos!!! Thanks for your previous help! I did the VLOM mod and cut the gaskets around the oil towers and removed the solenoids. Also blocked the oil pressure sensor port (cut a wedge out of the passageway from the pressure sensor to the galley that feeds the solenoids, and brazed a solid wedge back in its place while leaving pressure access to the oil pressure sensor). Also used your source to turn off the AFM. My new question is with everything done will this trip a CEL? California smog stations don't use the sniffer on vehicles newer than 2000, they just run a scan at the OBDII port. If the is light on, smog fail...Thanks...

Love all the video's, thanks again! But once i free up the valve, do i have to do the vlom mod still? How long would no mod last? Or how am i to be sure that was the cause of it collapsing to begin with?

[@CrazedPerformanceRepair]

The VLOM isn't why it collapsed. Lack of oil pressure during activation is why it collapses. This can be caused from several things but if you want all that message me on my website or search the forum. If you don't do the VLOM mod and tune out of AFM the already internally damaged AFM side of the lifter will collapse the first time AFM activates. So it could fail on first start or shortly after you start driving it but it wont take long. Everything I do has a purpose.

First off, thanks for the videos! I ordered the VLOM mod parts from you yesterday, because of a collapsed #1 intake lifter. Replaced lifter an still didn't do the trick. Start engine and lifter would work for 3 to 4 revols and stop working. Narrowed down to the VLOM solenoids so decided to try your Mod. Question is this..... If the Mod fixes my issue< will this Mod cause any engine lights? What do I do with the plug that ran the solenoids, do I plug it back in? Thanks again for the helpful vids!!!

[@CrazedPerformanceRepair]

The lifter could also be spun, you can determine this by looking at the side of the lifter. To see the side of the lifter you need to pull the VLOM and clean out the oil tower of the suspected lifter with cleaner and shop air. Once cleaned you can look down the oil tower and if you see a hole in the lifter it is not spun. If however you see only shiny metal or a flat surface then the lifter has spun due to a bad plastic lifter guide. When this happens you will need to replace the camshaft and all lifters. This would be a good time to do a full AFM/DOD delete where you remove all AFM components and replace them with non AFM components. Did you old lifter have any damage on the roller if so your lifter was spun.

[@miffyleslie]

@@CrazedPerformanceRepair lifter is right orientation. Blew air in top of tower on cyl of concern and blew air somewhat easily. Other 7 no air passage with air blower

Ask yourself, If it blew different than all the others, wouldn't that be indication of that lifter being in the incorrect position?

Great Video! I have a couple questions though that I'm sure have been answered but I 've read but cant find them. I purchased the lifter release trick and the plug. No luck getting it to release unfortunately. 1. If I do the Vlom Mod including the block off, what term would I use when asking my tuner to delete the system? AFM delete? should it be pretty self explanatory for a knowledgeable tuner? 2. Is it anything to do with E85 capability? never run it either way, just curious. thanks for the knowledge. Hopefully putting her back together tomorrow.

[@CrazedPerformanceRepair]

no, VLOM mod isn't needed for a full mechanical delete.

[@southseapirate1]

I need to do a full delete. Can I simply use the stock VLOM, cut gasket, your machined plug, and just use plugs for the oil towers?

If you plug the oil towers there's no need for VLOM mod with full mechanical delete.

Long story short: I have the plug inserted. Can I take the VLOM plate out and "remove" the plug? I assume some sort of fixturing the plate and carefully drill pressing it out, or based on your helpful experience whats the better way to go? Thank you so much.

[@catbird1759]

What doesn't make sense, if I did a complete lifter delete, and I'm plugging the holes in the block, why can't I use the original VLOM and block the oil passage from the oil pressure sensor going to the solenoids?

[@bcshumatey89]

Is a vlom modification necessary if you go ahead and get a afm/ dod delete tune after releasing the lifter but before cranking it for the first time? Would that still protect from it collapsing again?

[@CrazedPerformanceRepair]

It's need on the direct injection engines. The older pre 2014 can get away without it I suppose but you better test the VLOM for leaks first.

[@PeterBranco]

Doesn’t cutting the gaskets cause low oil pressure in the end?

[@mu9627]

I thought same, yet remembered the oil pump for those models is a higher volume pump than non afm motors and apparently is able to keep up with the bleed down from when the afm is activated and also with the vlom modification because the afm is now taken out of the equation. My interpretation anyhow. Great question!

When doing the Vlom mod to plug the passage, is it necessary to do anything to the computer to avoid a cel? My current issue is number 7 is bypassing oil and activating to both intake and exhaust Do essentially it’s a dead cylinder. I’m assuming that’s needing the vlom replaced… can I get by just plugging the passages in the vlom?

[@CrazedPerformanceRepair]

You would need a tune as well. I recommend lt1swap.com for this. However, keep in mind that your situation is extremely unlikely. If you haven't, you should verify that both rockers stop moving. You might only have one that's not moving and in that case it's most likely a spun lifter. This happens when the plastic guide tray fails. If it doesn't happen to be a spun lifter your camshaft will also be wiped out. In that case a full delete would be the best option.

Received my VLOM mod kit with tool today. Found your videos after suffering a collapsed lifter on cylinder 4 last week. Really wasn't hoping to spend the time and money on a full AFM DOD delete where I would use the opportunity to spend big bucks on performance heads and cam. If I had know about his crappy system being such a flaw I would have disabled it long ago. Light taps, heavy taps, big hammer, small hammer, slows taps, fast taps... After about 30 minutes I was about to give up hope and then POP out came the pushrod just like your videos. I sent you a message from the website, but figured I'd ask here. I did the second part of the lifter release to tap it back down a bit, but mine didn't move. Is it possible it just freed itself up to the correct position and didn't overshoot? I bolted the rocker back on and turned the crank over several times. The valve opens and closes fine now with proper tension on the rocker. Computer went off to LT1SWAP this morning before the tools came so I'll leave the truck off until it comes back. Just want to make sure I'm good before buttoning it all back up. FYI, the instructions showed the oil passage block off as in the videos here, but not the gasket mods. I did those because of the videos, of course, but others may not depending on which video they find your site from.

[@CrazedPerformanceRepair]

It doesn't always overshoot, you are most likely golden. If you can, bolt the vlom on and use the starter relay to crank it over until the rocker moves about 5 times. Then you are set.

Did it do it immediately after the repair? Was it multiple lifters? Once a lifter fails the system should be shut off even when replacing lifters. The lifters don't fail on their own. They fail from lack of oil pressure during activation.

I have a5.3 vortex in my 06 trailblazer and I replaced the lifters but now I am getting a piping noise when it shifts in and out of overdrive but not in 3 Rd if I drive it in that any thoughts

[@knotical689]

I'm seeing a similar problem. Pops when it goes from 8 to 4 cylinder mode. Ever sort out your problem?

[@Cherokee-sz7xi]

Ok ,, so what is the cheapest easiest most effective way to disable this afm system without a full delete?

[@CrazedPerformanceRepair]

Lt1swap.com pre l83/l86 and lt1swap.com plus my VLOM plug post.

[@MoDave82]

I have a question sir but does my 08 gmc sierra 2500hd 6.0 liter gas have a vlom ? I know it doesn't have active fuel management

[@CrazedPerformanceRepair]

No, because its not equipped with AFM.

[@MoDave82]

Are the 6.0 liter vortecs 2500 prone to lifter collapse or failure like the 5.3 ?

[@CrazedPerformanceRepair]

@@MoDave82 only if they are equipped with AFM. That that lifter issue is exclusively for AFM engines basically.

Would it be possible if I record the sound it's making and give me your opinion?

[@fhackman5863]

Hello, first of all thanks a million again for this hack! I'm back a year and a half after releasing a stuck lifter and doing the VLOM mod (07 Tahoe 5.3). Lately I've been dealing with low oil pressure warnings plus a heavy lifter tick only at startup that has grown louder, and I've tried a few fixes... Replaced a bad o ring on pickup tube and replaced oil pump. Tested oil pressure at filter to rule out pressure relief valve in oil pan. It looks like my last resort is worn bearings. Anyway I'm about to get a entirely new engine and my question is can I just plug the passage port on the new engine without removing the VLOM gaskets possibly voiding the warranty, or will the tower passages in the plate eventually clog over time and put pressure back on the lifters?

[@CrazedPerformanceRepair]

On a new engine just having system turned off is all that's needed. However, I wouldn't put a new engine in yet. the tick at start up is likely a broken manifold bolt, I have a video on the topic. As for the oil pressure, it's likely the second camshaft bearing causing this. I'm sure you guessed it, I also have a video on replacing camshaft bearings and I talk about it's relationship to oil pressure in it. When doing the bearings it would be a perfect time to do an actual AFM delete. Where you replace camshaft, lifters, valley cover and trays with all non AFM components. Sure you won't have a warranty but you will have saved probably $2500.

[@fhackman5863]

@@CrazedPerformanceRepair OK I just watched both videos and I must say you're the man! However with no shop, very little time now and pushing 350k miles on a former rental vehicle, I think I'll go ahead and retire her. Spend that extra for piece of mind on things. But I will feel around my exhaust bolts just out of curiosity. Thank you so much for your help!

[@richie818]

Do I need to do a vlom mod if I already did afm delete on the pcm ? Lifters never failed just did the pcm afm delete for preventative maintenance.

[@CrazedPerformanceRepair]

No but I would check for loose VLOM bolts and tighten them if need be.

[@nathanls14]

Does this work on a 2019 Silverado? Getting mixed findings.

[@CrazedPerformanceRepair]

If it still has afm. Some 2019 have DFM and it doesn't work on them. There is also a good chance that you just have a bent pushrod because of interference from the factory.

[@CrazedPerformanceRepair]

I should also note I have an updated video for the newer AFM engines.

[@mauricecleveland906]

Thank you so much.

[@davidmcdonald3654]

Will the lifter release tool work if the rocker is not moving?

[@CrazedPerformanceRepair]

If the rocker arm is floppy loose while the camshaft is not at the top of the cam lobe. Then it has a good chance of working.

[@keithlivingston1221]

@@CrazedPerformanceRepair Hey brother I appreciate your videos I am a fellow tech just learning about this trick from you, I ordered your kit from your website and my customer has this issue on cylinder 6 on a 2013 Sierra, I had the valve cover off for inspection and saw the intake valve does not move when cranked... But the rocker is not floppy, it is still spring loaded... Will your method not work in this scenario?

@@keithlivingston1221 no, that's most likely a spun lifter or one with bad locks. When it's not cranking can you rock it buy hand to compress the lifter?

There are other videos where guys are plugging off the oil passage towers . This may be for the full DOD delete with the DOD lifters replaced with non DOD lifters ! I'm sure this is were your getting the repeated questions from !

[@CrazedPerformanceRepair]

Yes, folks don't comprehend the difference between AFM and not when it comes to how it works.

[@TheEvan770]

Instead of the tuning can I order the afm delete module that plugs into the obd2 port?

[@CrazedPerformanceRepair]

Sure but it cost much more money and can come unplugged among other things.

[@colesampson9016]

If i just cut the gaskets do i need to tune

[@CrazedPerformanceRepair]

Yes, I recommend lt1swap.com for this. I also wouldn't just cut the gaskets. If your VLOM leaks it will cause oil pressure issues.

[@charlesstpierre8]

Around how many kilometers or miles in your case would you say this mod would be needed? Or should it be done because of a certain behavior with the engine?

[@CrazedPerformanceRepair]

It's done after having a collapsed lifter and using my release trick.

[@Bigolmutumbo]

Do I have to do the VLOM modification after releasing a lifter or is it optional?

[@CrazedPerformanceRepair]

You have to at bare minimum turn the system off in the tune. I highly recommend doing the VLOM mod though.

[@Bigolmutumbo]

@@CrazedPerformanceRepair I appreciate the reply sir ..... Reason I was asking is because I read in another comment that doing the VLOM mod with DOD lifters would cause them to collapse is that correct?

[@CrazedPerformanceRepair]

@@Bigolmutumbo Not sure where you heard that but it is completely incorrect. The entire point of my VLOM mod is for the lifter release trick I came up with for the AFM/DOD lifters. Did you actually watch the above video or just start commenting without watching it?

I removed all the mechanism under cover after vlom plug is that okay?

[@CrazedPerformanceRepair]

Yeah so long as vlom plug is in.

[@josephdillinger5538]

I just replaced all dod lifters on passengers side and less then 100 mile and the number 4 cylinder collapsed. Any ideas.

[@CrazedPerformanceRepair]

That is exactly why I came up with the solution that I did. It all comes down to low oil pressure at activation.

[@omararaujo5971]

Can a bad VLOM cause low oil pressure?

[@CrazedPerformanceRepair]

The screen filter in the VLOM can. The VLOM its self could but is incredibly unlikely and if it did would likely cause other issues.

i have 6.2 Gmc Denali 2007 deleted DOD , i am having low oil pressure when idling & i hear lifters ticking when cold start , at cold the pressure goes up to 40psi , when comes to hot it drops between 10 to 20 psi , i changed camshaft bearing and crank bearing , new oil pump & o'ring with new piston rings and every thing is sealed up tight , i am not sure about the valley cover o'ring since i am not the person who rebuild it , do u think the o'rings in the valley cover if not installed or become flat or weak have something to do the oil pressure drop ? i hope you can help me .

[@CrazedPerformanceRepair]

So with a full delete camshaft and all, some people will put the standard volume pump in place of the high volume pump. When this is done the oil pressure will be much lower. Do you know if you have high or standard volume pump?

@@CrazedPerformanceRepair i bought the oil pump oem by vin number ..i believe dod equiped engines comes with high volume oil pump ..

That being the case, I don't think the o-rings would be enough to drop the pressure that far. I would start to be concerned about bearing clearances. Did the crank need machining? where the rods checked for being out of round? How were bearing clearances checked?

When we talked you mentioned donating on my website.

It is interesting KZbin limits the thanks button though. Normally I only see $5-20 in that type of donation. I do greatly appreciate it though and look forward to a potential visit from a Canada customer. You would become the first non USA customer to actually service a non USA vehicle in my shop.
