500hp LS 6.0L Engine Build Part 4 | AFM DoD Hardware Delete - Save Your Holden Commodore LS Engine
HTML-код
- Опубликовано: 17 дек 2020
- In this episode, we take you through one of the most important preventative maintenance upgrades you can perform on your LS 6.0L as we delete the factory Active Fuel Management (AFM) or Displacement on Demand (DoD) hardware. This factory fitted hardware assembly includes a solenoid fitted valley plate, spring-enabled lifters and specially designed lifter buckets which must all be upgraded if you are planning on fitting a high lift camshaft and want your engine to survive - otherwise it will be a case of tick, tick, boom.
Our new valley plate cost approximately $300 new and is a standard LS 6.0L item and we will also be fitting LS7 lifters when our new camshaft arrives. This upgrade is part of a series of upgrades we are performing on our L77 6.0L platform for the new race engine we are building for our Holden Commodore VE SS track ute. We will shortly be upgrading the heads and camshaft with target power output in excess of 500hp normally aspirated.

Thanks for your very informative explanation of the DOD issue. I have a VF ute series 1 6.0L L77 engine that had the DOD disabled but still inside the engine. Had an exhaust lifter failure with the indicitave tick tick sound. Investigated and found one of the DOD lifters had failed and collapsed. Luckily no other damage but with a W407 upgrade with new cam, all should be ok. Car was already fitted with a w375 package but still cost me 7.5k to fix the issue with new valley plate, headers shimmed etc. Wow a big cost for a small lifter issue that should have been addressed by Holden at the time. Plus is I now have a 750HP new package. Love you channel, thanks again for the insight.
Hell yeah! Cannot wait until you guys get the cam fitted now!
We cant wait either Tom! Frankie is leanimg towards a BTR stage 5 or circuit cam. Stay tuned.
so yeah even if you aren’t sure, do the lifters. otherwise you’ll be forced (like me) to get a new cam, pistons, rings, bearings, heads … and lifters :D
Amazing how Holden just continued making dumb mistakes through their life. Almost like they did it on purpose to create work for mechanics. Faulty V6's with plastic LIM's on earlier ones and stretched timing chains on later models. Not sure why Holden is not paying to repair all this.
Very interesting to see what the lifters look like. Great video. Thanks for that
G'day Clemmo, let us know how you go with your lifters.
Will do. I’ve got the car booked in with a mechanic that can only do the job in July. He’s snowed under with work at the moment
hI GUYS i CANT THANK YOU ENOUGH FOR THE AFM delete segment my 2012 ve ute has been done and with some small mods it performs the wayI want it to THANKS AGAIN
G'day Trevor, glad we could help and fingers crossed you removed the DoD in time. Check out this video for some more preventative maintenance - ruclips.net/video/plgGGRam5jE/видео.html
Great video now you need to show us how to swap the cam so we can do it ourselves
G'day Tone, yes we will do a full in-depth video on the cam change. Will be a much awaited video given the interest our viewers have expressed to date!
Awesome video,ive got a 2011 ve ss with afm,got it new i change oil every 7k now and i drive it normal i dont flog it,its done 225000kms should I be worried or considering the frequent oil changes and the way i drive it i can get another 50-100k out of my lifters,they don't make any noise no rattling
'DUD Lifters' hahaha
G'day mate, yes classic comment previously by Frankie! Thanks for watching our videos and commenting.
Very helpful and informative mate, can U do a video on cam timing and replacing the cam?
G'day mate, absolutely. We will do an entire episode on the cam install and will provide detailed instructions on the whole process.
Lucky the L98 didn't have any pf that AFM crap installed . although the standard lifters always go in them
Too right Michael! We dodged a bullet with the build date on the VE as it came with the L98. Lifters are still a weak point in them but they are the standard roller items and not the design debacle we showed on the video as per the L77!
Also seen US Holden Caprice police cars running the AFM system for over 200,000 miles due to correct oil changes and regular oil flush systems and most of the time the cars are sitting doing 100's of hours just sitting at 700 revs and not doing hi speeds, or hi rev's/ oil pressures are the issue and not the lifters, sometimes they do but mostly at ideal and no problems if you want to make HP different thing then, but again must do it right and with people that know what they are doing when it comes to DOD deleting systems and products used and other aspects of L77/L98 GM engines?
Hey men I’ve got a VE SSV 6 Speed auto L76 dream car I thought when I bought the car from a car yard that it had a cam kit installed in her but it seems like they just ripped me off with a few things and just put a cam in it only could you give me any advice on where to go even online also my lifters are starting to make a tapping noise so I need new lifters and delete the dod AFM I’m in qld Brisbane cheers men
She's THE duck's guts - fixed
Awesome videos guys,I've got an L77 manual with 80,000kms,im cringing at the sight of those lifters and trunnions...where do you guys buy all your BTR items? I can only find in the USA? Keep up the great work!
G'day, Inthink you can buy BTR online directly but we get all our BTR gear via our local tune and performance shop, Gentech Automotive in Canberra.
Why they would put a DOD or AFM on a v8 for is beyond me. You buy a V8 to not save fuel lol
G'day Curtis, a good question for GM! I think it was mainly so GM could compete on highway mileage figures for fleet buyers, families etc..
GM and particularly Holden always found non creative ways to meeting emission controls etc. Like those PCV valve systems many models ran to gunk the intake in oil.
I am from America, so we have the G8 version, but same car. So I bought a g8 a bit ago, and the guy said it’s supposed to have the DOD delete, and an LS9 cam. May seem like a dumb question but it possible to know if it actually has the cam and dod delete without busting the motor open? Mine doesn’t do any of the things you described, (it’s NA) but I don’t really know if the guy did what he said, and I’ve never driven a stock one before. It’s an L76 6.0L and I have plans to boost it in the future, and am being my research. Any advice would be appreciated, and great video nevertheless!
What was that book on LS engine repairs you recommended in one of your vids? I can't find the clip where you show & mention it.
G'day mate - you can order the book on Amazon. Here is the link --> www.amazon.com.au/How-Rebuild-LS-Engines-Design/dp/193249460X
Does DOD delete require tuning?
will we need a tune after this? i have to replace a broken lifter in my l77, but if im in there i might want to go with a dod delete kit instead.
Yes mate, you need to remove the hardware and also disable the AFM in the tune.
They are some strange looking lifters, those DOD lifters. Are you using Brain Tooley LS7 lifters as a replacement?
G'day Angry, yes those DoD lifters look like something from Mars. We are leaning towards BTR LS7 lifters in the new build - nice guess! Did my t-shirt give it away?
hey clunie im pretty confident of getting the lifters, DOD plate, cam and valve springs replaced but. Who can de-activate the afm and adjust the tune. Previously having afm the oil pump is already high volume from factory why would you need to change it?
Unless you're building a loose tolerance LS for high rpm race work, you don't want a high volume oil pump.
There's a pressure relief valve in the sump, that just sprays the oil all over the crank, to keep the pressure in check. Three problems with that, your fuel is providing the energy to pump that oil for no benefit, when you're pushing the motor, some of that oil will get past the oil rings, especially on compression braking and finally the increased oil mist in the crankcase, makes your PCV system work harder, potentially fouling up your intake.
Hello mate, any reputable tune shop should be able to de-activate the AFM software and adjust the tune. Our tuner uses HP tuners. Let me know if you get stuck.
First as usual 🙏🏻
Well done! Always the early bird!
Hey guys, I'm a little late to this video but just hoping for some advice.
I have a VE SS with AFM and just like you mentioned towards end of video, it rattles at low rpm when it's in 4 cyl mode and the occasional tick at idle. How far gone is it and am I in trouble? Or do I go do an AFM delete asap?
Much appreciated
also intersted, currently in same boat
Tune out your AFM and put a little of the thick oil additive in for one oil change. I still have the shitty dod lifters and was having that problem so i tuned it out and put in the thicker additive and it helped for now. It still ticks on startup sometimes but goes away after it idles for a minute
@@Str8Ripper1776 I had to get rid of it because it was starting to become drama after drama on top of the lifter issue. I did put a thicker oil in it but didn't delete afm, not sure how much better that made it because it would still tick for a couple minutes on cold start. I think safe bets that majority afm models would have the same dramas. I think that's my first and last afm. Thanks for your reply though
What was the plastic under the valley cover for ?
G'day Proper Aussie, I believe it is part of the PCV system/vent. Will do some more investigation and will let you know when we assembly it fully.
I am looking to get this done to my VE SS (Auto L76)
I purchased the car 4 years ago with 103xxxkm and went and got the AFM disabled via software because I wanted to put a catback on the car and didn''t want to hear it drone in 4 cylinder mode.
Car now has 122xxxkm, I cannot hear any signs of lifter issues... yet! Just don't have the knowledge to do it myself or the equipment! Will need to find someone in Melbourne
G'day James, well worth doing as the AFM software may be disabled but its the hardware of the lifters that is the key issue. Lots of performance shops will be able to fix for you. Get a cam at the same time and do a job of it!
@@ClunieGarage Yep defs getting the cam changed while I am there!"
I was going to get a manual V8 and sell my VE Auto V8 but the VE is such a clean car compared what is out there, plus the pricing Commodores these days...
Is this l76 engine
Hey guys - I friggin hope you are still there. I am 65 and about to embark on my dream - to make a replica 70's Sandman Panel Van. Problem is the van I have chosen is a 2010 VE (one old owner) with 134,000k's L77. The one and only mechanic to ever work on this car made this comment -
"Previous notes carried forward.
-Crankshaft making noise (squeak noise) known problem
Lifters or possibly camshaft
-Serv light not on."
Is this valid?
Should I be expecting big bucks in the future if lifters etc are screwed. Please help. Appreciate it.
Do you do this work for paying customers at your place?
G'day Dan, unfortunately not. We are just an enthusiast channel workimg on our race cars. However, all our professional mechanical work is performed by Gentech Performance. Their link is in the description of the video if you are interested.
Ok thanks, for a DOD delete, cam, bigger clutch. performance mechanics are asking around $10,000 some even $11,000 here in Brisbane.
That’s a huge price tag, I wish I could do it cheaper
@@dankoz3286 yes, these cars are not cheap! I know that a cam upgrade inclusive of DoD delete is $6k drive in and drive out at the performance shop I mentioned. However, even if you go with a Mantic clutch or similiar you should have change from $9k.
I have the manual L77 so it's not activated but does the DOD still effect my engine
I think you already know the answer to that one. 😩
@@angry9901 Dammmmmn gonna have to get it done 😔 there goes 1k
G'day Dr, yes unfortunately you will have the same hardware as shown in the video. Unless someone did the DoD delete before you bought the car!
I had L76 had AFM shit 120000km fully serviced if solarnoid goes kills engine now I have L98
@@rodrum7478 Does it destroy the engine?
How much you charge to rebuild my 6.0 l76
G'day mate, we don't work on engines other than our own race cars but I can connect you to Gen-Tech for a quote if you are interested mate for a good deal?
What's the estimate cost of an L77 DOD DELETE?
The tune shop we go to normally charges about $6k but this includes cam, tune and all the lifters, valley plate etc..
yeah thought as much.. Holden should never have done DOD.. The petrol savings were so minor compared to the to damage cost it would cause later
2nd
Well done Dan Sunny Boy. Are you thinking of doing a DoD delete?
Hi I have the l98 in a ve ss ute similar to snot box ,it's ignition orange ,so don't need dod ,but I enjoy watching
@@Dan-oj7cd thats good news that is has the L98! Thanks for watching the channel mate.
