Love the vids and love how you own your mistakes so others don’t have to go through the same !!
Towards to end of the video you sounded depressed Scotty, don't stress about it.
As my old man said to me when I was young, If it has tits or tyres it going have problems and cost a shit ton of money
Your dads name isn’t Geoff is it because that’s exactly what my old man said to me 😂
@@shaunpc2512 hahaha no no
Another piece of advice. If it floats , flys or fks ...rent it
Truer words have never been spoken.
@@trentmarlowe7655 cheers mate
Block the 2 coolant ports on the top of the LIM (yellow O rings), either weld or tap and plug (1/4" NPT). Than you can remove the blower in the future without needing to drop the coolant. Whilst the heads are away, have them check the valve springs installed height, and full lift etc to make sure you have enough available valve lift for the cam as stock heads are only good for about .520" lift and your cam has much more.
You and the crew do a great job doing what you do. Set backs will happen, keep kicking butt and continue making great vids.
Cheers.
Ah far out. Bloody Supa Mang!! It will be worth it in the end. Thanks for sharing.
The trials and tribulations of performance modifications. Keep up the good work love the channel.
Back when I worked at a large engine building place. At least 50% of the heads we took off the V6s were binned due to cracks. Only if we couldn’t get spares would they repair them.
Proof that "crack" is bad. That is all.
Whats the common reason they crack so often?
@@smithy2 Likely poor casting. Other than that extreme heat cycling.
@@Burn377 wonder if they'd do better running on meth or ethanol rather than petrol? 🤔 bit of a power gain too
@@smithy2 just a design flaw. Heat mostly, it’s always between the cylinders. The VR/VS were worse.
Bwahahahah love the title. Always look forwards to these coming out on Fridays
Smooth off the sharp edges on that piston damage or you'll get some pre-ignition/pinging. They'll get hot. Good show. Always fun opening boxes of new stuff
Thanks for another quality episode Scotty If it was easy everybody would be doing it . Keep up the good work
Keep pumping out the vids scotty. No matter what
I am keenly interested to see how the Super Mang goes once all the problems are solved. Love your work Scotty.
Can't wait to seee future videos of the supermang
I remember changing the head on the hj45 and the "replacement head" had 12 cracks in it before I got it half way out of the packaging. The skippy badged head I put on it 12 years ago is still doing it after some HUGE petrol radiator drama... The hj47 radiator has stopped the #4 pot combustion chamber from beading... The new heads will be good. So worth it!
Mighty 2H
Sorry to hear about what's happened to your Supermang VN Commodore unfortunately these things do happen surprises to happen so it does take a little bit longer for things that we want
Plenty of time . Best of luck, keep up the great content..
Bloody Supermangs...I had one in the shop today running very poorly and I recon the heads are cracked on that bugger too.!
Gonna have to take me for a spin once we finish those heads, then once I get my turbo on I'll show ya how the l27 3800 partys
Flappy disk the piston and send it, if it explodes/damaged the rod bearings you get to make a "Mo mang? No mang" episode title.
A bit of bad luck with the T chain Scotty, but you wouldn’t of known the heads were that badly cracked mate.the dark cloud has a silver lining and with the new bits you have for it it should have good Dyno results.Good luck. 👍👍👍
Chin up scotty it wouldn’t be carnage without shit going wrong. Love your work buddy
Cant wait for the next update on this rig so much goodies going on
Scotty mate you should have the mechanic's trolley set up with small plastic containers labeled so you have every important items taken off put in the right place, so that when it comes time to put everything back together you have not lost anything, my friend did this and had a 9 second White HR ute NO Plate was SWAN 01 and he built the engine himself, sure got everything from performance aftermarket items, but still done well and this was back in the 1980's? I told him to go auto from a top loader and he dropped a 1.5 second just from 4 speed to auto, also no turbo just straight out engine performance?
Silver lining mate she will be even more of a beast now!
*Scotty: You were correct in your assumption however that this build would be "Off the chain!"* 😉
I just fitted the a2a plate to mine, there is a few mods that need to be done to make it fit properly. I can give you the changes I made if you want to save you time
Please lol. My motors at the machinist for another week.
Im doing a cam kit now and double row is a must. I would pull this motor put some new rings, hone cyls, bearings and oil pump gears from mace. It aint going to last long at 400k+. Rodney will decide soon hes had enough. Btw your et to beat is 13.0.
I called it from the announcement of this project that supermang would go superbang, its not that you did a bad job but those L67 are a base Buick motor which runs okay na but had many weak points which surface quickly when boost is added. There no barra and need alot of supporting mods to make and keep them happy but then again once road kill became country restricted carnage filled that slot quite well right down to the consistent problem but a bonus like mcm is aussie content. Like why haven't you guys done a collab yet with
Is it worth while doing a strong bottom end with new rods and pistons. While down and bearings. 🤔🤔👍
Fingers crossed you get a hold of a decent set of heads .... L67 heads loved cracking between the valves 😣
Tough break man. But now you have an excuse to upgrade and the Mrs/Boss can't complain as much :)
Do you need to change the blower snout? I believe yella Terra make one that bolts to the m90. The smaller pulley looks like it would interfere on the standard blower snout.
We have a snout
Looking forward to the next mang video.
Are you guys doing an a2a or a2w intercooler?
I just had an l67 built and I'm doing a a2w set up. Shit loads less cooler piping work needed, and been proven over and over to be way more efficient with intake temps. Its just a little more wiring for the water pump and fan/s (don't need to run fans but it always helps)
My mate was actually talking to one of you guys about a start up tune for my build for the haltech
I love this but I think I would be wanting to look at those con rod bearings - they have taken a big hit to mark the pistons so much. Want to see this go forward strong not backwards, keep it going👍👍
Hi scotty will you need to work out piston to valve clearance again? I reckon timing chain broke cause of the valves hitting, putting strain on chain.
If valves were hitting every piston would have marks
Hindsight is a wonderful thing...
have you looked at zzp online they specializes in l67 engines
Yeah i remember seeing years ago they brought out alloy heads
Don't beat yourself up about the timing chain man... we've all been there fitting a part only for it to fail. Keep up the good work and keep smiling.
Genuine question though... how far can you take an M90? In my experience I have found them to be a heat pump, even with water/meth injection..
MMM last time I pulled a Commodore V6 with a cam and a broken chain it cracked the ring grove at the top of the piston.
Scotty just pull the dented piston to check block in car. You have a hoist.
High load and boost top rings never ever seize and take out chunks of piston. Do they?
The more I think about it, I might just pull the bottom end and do another. Swap the cam from this one to that one.
@@STREETMACHINETV Might as well just put in a Forged bottom end with the appropriate ring gap. Far less messing around when turbo time comes around.
@@dazaspc the idea was to see how we could do on a standard bottom end
Welcome to this episode of Re-Do Garage.....😂
What can you do Scotty It’d be boring if everything went to plan.
Thanks for the great content cheers Pat
Scotty has the Dream Garage...
Can you put flat top pistons with valve reliefs in that motor? More compression would wake it up some
Scotty, have a spare set of l67 heads, I believe they are off a 2002 calis or xu6
Flicked you a photo on instagram
I'll check it out, thanks
LOL I did when scotty did the count drac count, LMFAO keep up the great work scotty mate?
You can tell who has kids :)
@@STREETMACHINETV Scotty I think is also the fact that you probably grew up on Sesame St as I did because we are the same age, and it was on the ABC during our early childhood
Now that there is a lockdown in Victoria you should work on the valiant wagon. Good video though, I love carnage so much
That's what I'll be doing next week.
V6 engines are cheap, it's just that the hot up parts are expensive. Indy guys were getting 700HP+ back in the day, so the potential is there.
Shocking that a chain like that failed so quickly. It looks way beefier than what they use in a Barra. First time I saw a Barra chain, I though someone just pulled it from some kids 10 speed!
And of course the L67 used different heads to the L36 so you can't just go to any junk yard and source what is required.
The 6.3 hemi into the vn 😁😁
Ouch, that really sucks. Thought yep, valves, pistons, port, all good. The amount of cracks in that made me wince for ya. 🥺
After looking like being the first to race you last year, then Covid swapped everything around and looking like being the last to race you after Big Dawg and Zane, seems like I'm now gonna be the first again in a few weeks. 🤷🤣
The vl Calais rims look nice 🤤🤤🤤
Curious why you went an air to air for the charge cooler and not a water plate?
Simplicity
@@STREETMACHINETV makes sense haha
@@TheBondy666 the w2a plate is too thin to effectively cool the boost mate, a2a plate with external w2a core is the best setup for this engine
Should've gone double row. Straight up!
hind sight is always 20/20
like to add to piston swapping is turn piston front to rear as well whoops peace
Scotty need to replace pistons could cause a hotspot at the least get some from mace.when replacing swap piston around like 1 to 2 and 2 to 1 so on.why it off set the pin angle piston will sit straight at tdc quicker acceleration. Peace
This is a good lesson to those who want to upgrade their V6. Chuck it in the rubbish receptacle and do something else, an LS conversion would be cheaper and more reliable, probably weigh less.
Aren't you replacing the pistons? Are they ok like that?
i was thinking whilst the engine is stripped down this much, would it really break the budget to put a set of new bearings and pistons for added safety and insurance? just saying........
More Mangs, More Problems sounds like it could be the title to a Bogan love song
throw a nitrous port in the outlet of that plate ? now that's some spicy mang 😂 I know theres a bad joke there somewhere 😂
I'm calling it, Supermang is the new Trolvo.
The look to camera at 7:30-7:32 killed me. I saw the look in your eyes, the look of; can’t any toy in this workshop be right? Why me?
is that the i wanna swear but i won't look?????
The moment I saw your face, and the colour of that coolant... You had an idea there was some fuckage in the head region.. 😉
BTW, where can I get a longer extension?? 🤣😂
Could u use an air to water intercooler underneath the bower keeping the air path short. Or is it a $$ problem
Everything is a dollars problem. But we might try both
trying to remember what size cam you put in her ? probably a biggun being an Aussie.
You've gone from Supermang to Nomangsland
Did you get a timing chain from an Alloytec 🤣
The Trolvo took a while to get sorted but look at it now. All part of the journey.
exactly
How’s the clearance to the bonnet going to go with the A2A plate Scotty?
Yeah that'll be interesting
I’d love to know what your plans are for the xr6 would really love to try and do the same to my au3 falcon
With a lot of power chasing it's 1 step forward and 3 steps back especially when you're not going the tried and tested way. It will be a weapon as will the Trolvo just a lot of trial and error...........
Time to pull the bottom end out and stroke it whilst waiting 👌👌👌
Scotty why don't you stroke the bottom end while you wait for heads. I suspect you probably have a cracked piston anyway.
What's the stainless steel pipe that the coolant was in called I need one to install in my VY HOLDEN COMMODORE ACCLAIM 04
The main problem is that it's a Holden right?
don't forget the jb weld on that piston
I like how long that extension bar is
I want one that big 🤣🤣
Hey scotty. I have a wl stato ls1. It's off the road atm as I'm not sure what is wrong with it, it overheated a few times and went in to limp mode. Changed the water pump thermostat, rad and still no good. I was told head gaskets, I had it running and sounds a bit fkd. Pls help
If the water pump and radiator are new then head gaskets are likely. What does the oil look like?
@@STREETMACHINETV looks a bit milky, I have a video of the car running if that helps to diagnose the problem
@@redemptiongarage5856 if its milky it'll be head gasket for surr
Ever considered putting wing nuts on that engine??
LOL
L67: costs twice as much money to make half as much power as an XR6 turbo and still bends valves, cracks heads and breaks timing chains.
Man, I feel so sorry for Scotty. He's such a nice guy and just always seems to get let down. Keep your chin up, mang!
I question how serious those cracks really are if half of all ecotecs/L67s are driving around with them and having no problems. They seem to be blind and not a source of leaks.
good excuse to practice your welding?? lol
You're an American youtuber now, build blow up repeat. Did the heads on both my L67 Calais, not as bad as that though, shibby.
Was it an iwis ??
Is what is mate, but you'd of thought, you'd get more than 2weeks out of a timing chain, find the very odd, it's like that chain was defective before you fitted it, like a manufacturer issue.. understand the mods to the engine, but 2 weeks... anyway..least your sorting out now
.
Are the manifold insulation kits from mace worth the pop ?
have friend with an L67 in an escort, 400Kw, low 10's. that's a flogging and he has had no probs with them, well worth the cash
YO YO YO MY FAV FRIDAY MAN LOL
HAY SCOTTY PS I WILL SO ITS ON THE BACK-BURNER LOL
Oooof, that chain gave all she got Cpt.
The double wasn't in the budget, but head work was... :P
As I mentioned in another comment we put the engine together back when Coronavirus first started and budgets were slashed. Since then things are better and we have money to spend again
@@STREETMACHINETV Yep, i know it is just that funny thing of small thing leads to a big thing.
Though the big thing is the end goal.
How about porting the blower while it's off?
Thinking about it
@@STREETMACHINETV it's definitely worth it for the extra gains
Just commenting to get my like from Scotty :)
Dont forget to regap the rings or you WILL rip the tops off . When you put the cooler in and the silicone bends you need to slide a metal bend inside the silicone pipes because they suck in under vacuum . My friend leon owns awesome auto in adelaide and is the gm guru on the v6 engines and knows all the ins and outs of all gm software and engines . Go ring him up for advice if you want . You really should have gone for a water to air cooler instead . The air to air suffers from heat soak . They put out good hp but do have trouble . Get intouch with zz performance in the states and try to get a set of their alloy heads if they still have them . Go hard or go home i say . You really should change the pistons because they are shit stock . I uesd engine tech ones from the states or go some je forged pistons but they are pricey though .
What's up with the 1 metre long extension bar? 🤷♂️😂
Hope new valves are in your budget. Probs more expensive than timing chain
They are now. Got the remember we put the bottom end together during the start of covid, everyone's budget was slashed
Only about 12 bucks each for stockers, or Mace used to do good quality stainless for not much more.
What do you expect it's buick v6
DUDE did I spy a Ryobi (Cryobi) green battery wrench..... if so the budget REALLY IS tight..........
Yeah flappy disc it, the comments would be priceless.
Is head cracking on the 3.8 common?
yes, but more common on the L67 or if overheated.
Scott, Excellent Hungarian accent while doing the "Bent Valve" count. Be careful, you don't want vampires to suck out your coolant ;)
I was thinking more along the lines of the count from sesame street 😅 the number of the day is .. 3 ah ah aaah 😂😂
@@jamesmitchell811 Exactly! The Count (Dracula) is supposedly Hungarian (as is my wife ;) ).
what about a forged bottom end?
One day
