@@brando7655 I mean the engine was built by a professional, with good quality parts. And it will be tuned by a very reputable LS tuner, so I don’t really agree with that.
@@brando7655 definitely not the case. The highest quality parts, built by professionals, tuned by a reputable LS specialist, with support from the manufacturers themselves…. People do always make mistakes but as a whole this isn’t due to Brian’s quality of work. He’s shown over and over how high is quality of work is on multiple channels.
B-haul! To me you're a critical part of the gang that tied me closer to Jimmy and this channel than other builders. I can see the pain in your heart through your eyes. I can see Jimmy feeling the pain since he's putting so much wrench time trying to diagnose. Definitely hurts to see but keep pushing!
I was having some weird misfire issues with my ls swapped e46 and I found that the grounds on the back of the heads on my setup were a little lose and made mine misfire, but I'm sure you smart men have checked it out.
I had this issue as well even on my stock vette, found out one of the ground cables were destroyed at the back of the head. That area grounds the ecu/coilpacks
A couple things to check. Coils are going to the proper cylinders, coil harness plugs are on the proper cylinders, and also make sure the settings in the ECU are for the respective reluctor ring on the engine.
@@ChittyPA I was slightly impressed when he said that. Then I seen how he treats other people, on camera, in front of others, and well he might have a half mil but that doesn't make him any better than anyone else.
I had a decent length response typed out , realized you just tried to tell me, that because Derek is jokingly an asshole to his friends on camera, he obviously doesn't know 3 very basic things to check while diagnosing a misfire 😑

Brian definitely feels like he’s part of making everyone else’s car look good and come to reality and his just keeps hitting a brick wall but rest assured you guys will overcome this! And i wouldn’t mind the next 2-3 videos making sure this car gets right, after all Brian deserves it!
Not the video title I want to see Brian is such a great person hes worked so hard on this build and is always helping his friends he deserves a win....sending nothing but positive vibes to you brian!❤
Just a wild guess, are the rockers hitting the valve cover? Did you change the valve covers to accommodate the new valve train? Was tough to determine watching the video. Anyways, good luck, Brian, you deserve a win - hoping you get the issue squared away.
Hope you guys figure out the valve train! I always stick to johnson lifters and the do the BTR bearing upgrade in factory rocker arms. It’s pretty tried and true. Sometimes if it’s simple and works don’t over complicate it. Stay away from ls7 lifters tho.
Big Cam + sketchy behavior Hydraulic lifters + unknown ratio rockers = lots of questions. I would look into the compatibility of those parts. The problem is in the valvetrain Jimmy ...sounds like the valves are randomly being over-lifted and not seating on the seats(which WILL cause them to be damaged by overheating).
Go back to oem ls7 lifters and oem rockers (with a trunnion upgrade for reliablity, and check pushrod length. Put in the right length pushrods and shell be mint
Not trying to backseat mechanic, and I'm sorry if it comes off that way. Could it be a voltage issue in the harness possibly? I would imagine you would see that in the data once you get it to the dyno right? Just spitballing ideas around. I'm sure you've already had that thought! I tend to over look or assume things when I'm frustrated, but who knows! I'm sure you boys will get it right!
Yeah it feels like one of those weird electrical issues where a ground isn't quite tight, a wire isn't quite connected fully or something. Absolute bitch to hunt down but who knows really, can't really tell over the internet and I'm sure the guys know more than I do anyway
@@helplmchoking yeah, like I said just spitballing! Never hurts to have extra brains. When everyone is frustrated and over worked things get looked over. I'm sure they'll figure it out once it's on the dyno and they have more data to look at as far as tuning goes.
Double check the injectors and coils are pinned end to end correctly to the correct cylinders. Having two coils out of order will make a hell of a time
In the world of Fox Bodies, hydraulic lifters and stud mount rockers are common. You typically would always set valve lash with the lifters pumped up. On a SBF you start with cylinder number one at top dead center, rotate the engine by hand until you see the intake valve start to open and set the exhaust rocker and then rotate until the exhaust valve starts to open and set the intake rocker. You follow your firing order to get through the hole sequence. When setting them, zero lash is achieved when you snug the adjuster by hand until you feel the slightest resistance when trying to spin the pushrod. On a SBF you typically set your rockers @ zero lash plus 5/8 of a turn to compensate for slight hydraulic compression of the lifter. No feeler gauges required, that's a solid lifter thing. Hopefully you see this and it helps! Good luck fellas!
As a diagnostic technician who doesn’t work on modified cars/engines and just looking at this as a potential multi-cylinder misfire, here is what I would do at this point. Use a PC based oscilloscope. Install an exhaust back-pressure sensor somewhere downstream of where the headers meet. Install a lead on cylinder 1 ignition coil or injector as a sync. Run engine and look at data. All exhaust pulses should be almost identical. If any are abnormal, you will know which cylinder(s) are having issues since you know the firing order and you can see cyl 1 firing. The only problem here is that a scope that is capable of this test is very expensive… however maybe you could borrow one from someone.
LS GANG! I can't wait to see Brian's car rip!!! I love the LS3 in my 2016 Chevrolet SS sedan. This video is encouraging me to get my SS out of the garage and take it for a rip on this 46 degree Ohio winter day. Much love to the Oaks crew.
Exhaust pulse is gaining to much speed from high flow head ,so the pulse from the long side is more powerful than the short side ,causing Exhaust pulse to reenter cylinders or at least back them up ,this will change with higher rpm ,the reason people don't come across this is this engine is flowing so much more than a stock LS with the one backwards header/Exhaust manifold ,just thinking.
We've been there before where we double checked everything as it went together all brand new parts but it still didn't work. Faulty new parts are getting more common now. Fingers crossed 🤞 that's it works for Brian
Jimmy, great job teaching/explaining that to us/DJ. Your approach to teaching/ checking for understanding of the rocker arms was better than some of the teachers I work work …
Dammm Brian such a good guy he needs a win cars been down too long. Wanna see him smile drifting. He always helps everyone he needs a W. Rooting for him.
Brian deserves to have a 100% working and reliable car I've never seen anyone work harder to get what he wants, I'm sending my good vibes to Brian hoping it gives him luck to finally have a fully working and reliable car
Since the heads are cnc'd, the rocker boss will be machined off inside the intake runner. If the bolts are not sealed off with rtv, they can cause issues also. Or if you have an open pcv system at some point, it will introduce more air into the system behind the TB which is also an issue. Thats why most builds should not have a breather on the valve cover or be vented to atmosphere.
one thing I have actually run into with unequal length headers is try running them open, no pipes, see if the pressures from cylinders arent causing issues due to the duration of the cam and lobe seperation. I know ir sounds wierd but I have seen this cause idle and low rpm issues. EDIT, your manifold issues are causing problems, not to mention after the last reassembly you were having serious lifter tick. I love your vids Jimmy but this car as more than one issue that is causing problems. One suggestion try the gto manifolds from holley and join them behind the trans.
Yes let go b hall!!! so happy you get to see the light at the end, you have worked so dam hard everyone has. Hope it does good on the dyno... and you need to start callin him magic man spoon, that dudes a wizard!!
Buy factory rockers and measure for proper pushrod length. I had a buddy that had the same setup and could never get the preload correct with adjustable lash on the rockers. He went to solid roller lifters.
Jimmy, as much as I appreciate your hard work ethics and style that you put in cars, your skills at troubleshooting are extremely impressive. This is what I admire most about you and your channel. Hope B.Hall gets it all figured out but I'm sure with time, it'll be just fine. P.S. I miss Yung Tuck.
A super tight high compression NA motor can take a bit to seat. A few heat cycles and some running time can seriously make a huge difference in completing the build. Nice job on diagnostic testing. I'm sure it's gonna work out. BHall deserves a Win!!!
said this like a year ago that stock LS3 with a mild cam would have been enough for Brian. It sucks that hes still fighting this thing. As an E46 Sedan owner and LS fan, i hope to see it sail. My 04 HCI GTO was a blast to drive.
The adjustable rockers are questionable and recheck rod length. Stock rockers with a trunion kit is the way to go. Made well over 6-700 HP with them. Also lifters fail right out the box and seems like you guys have some stubborn lifters there. Johnson lifters or OEM ls7 lifters are the move. Used them in a lot of builds. Excited to see the e46 make some jam!
Man, I fully expected this video to end with spun bearings or failed dry sumps again. Glad it isn't the case. You'll get it figured out, we're all confident in you.
I've actually had a similar issue with my 4g94 Mivec (mitsubishi version of the honda b20 vtec).The hydraulic lifters were the problem and as soon as i swapped them out with new lifters and readjusted my valve clearance..she was as good as new..i hope that y'all make progress and the next video to be uploaded will be impressive dyno numbers and smiles from Brian
@23:33 make sure fuel pump isnt over drawing the circuit, an amp meter can easily test this while the pump is under load, more often then not people upgrade pumps and never upgrade to a new relay circuit capable of handling the amp draw of a larger fuel pump. this will cause idle/ load issues. not saying this is your issue, but is a place to look
Are the coil harnesses swapped side to side? This can cause issues.. also, are the ignition harnesses grounded to their corresponding cylinder heads? Holley is SUPER picky when it is not grounded to the correct cylinder heads.
Check the coil pack harness pins to make sure they are fully seated. I had an LS give the same issues and backfired on the dyno just like your explaining.
Just shooting in the dark, would it benefit to switch to regular rocker arms, soak the lifters over night and measure for proper pushrod length with an adjustable push rod and narrow that out the equation? Hoping for the best for B-Hall and his 8 cylinder boxer engine lol
I would honestly throw stock style rockers on it with the right pushrod then run normal ls7 lifters along with checking grounds you can make good power with stock rockers with the trunnion upgrade
Good luck Brian, I feel you, struggled with an old Honda CX 500 for years, loved that damn thing and kept throwing money at it but never got it to be just right
Ls7 lifters, correct push rod length, trunion upgrade rockers= mint. I feel like those rockers that are unnecessary are unnecessarily causing you guys issues. Best of luck
Idk if ls engines are 100% the same, but I've done a couple sbc engines and no matter what if you have hydraulic lifters, you set preload, not lash, on small blocks I'd always go to 0 lash plus a half a turn of preload
@@flamin5.833 okay. That makes more sense of the wording you used. Didn't know what you had experience wise with LS. Between my brother and I, we have 5 Ls swaps, 3 swaps including turbos making 850+ at the wheels.
Aftermarket cam, ls7 lifters (soked for some time). 7.4 LS Chromoloy push rods, oem ls2 rockers with trunion upgrade. .660 valve springs. And send it! Tride and true
Man you can feel the frustration through the screen. Unfortunate for BHall, hopefully it’s a simple fix and nothing major. With everything that’s gone down with this build, Brian deserves a big W.
LS isn’t that complicated. Idk how someone can have this much bad luck. I barely knew how to do an oil change but built my LS; even cut my own rings. Almost 2 years later no issue. Banging rev limiter. Best of luck to Brian

Normally, you would not set lash or have adjustable rockers on an LS. They would be pedestal mounted and you just torque them down.
@@Axial32 normally yeah, I have a 6.0 in an S10 that has the factory pedastal mount rockers, I was more so referring to the adjustable ones
@@flamin5.833 okay. That makes more sense of the wording you used. Didn't know what you had experience wise with LS. Between my brother and I, we have 5 Ls swaps, 3 swaps including turbos making 850+ at the wheels.
Appreciate all the team coming together to help out Brian, this car deserves to rip
Monster cam and super custom valvetrain gonna be a pain in the ass.
Aftermarket cam, ls7 lifters (soked for some time). 7.4 LS Chromoloy push rods, oem ls2 rockers with trunion upgrade. .660 valve springs. And send it! Tride and true
If DJ's gonna get it, you guys have to get it!
WOW xD
Man you can feel the frustration through the screen. Unfortunate for BHall, hopefully it’s a simple fix and nothing major. With everything that’s gone down with this build, Brian deserves a big W.
so happy to see brian's car getting ready to shred!!
LS isn’t that complicated. Idk how someone can have this much bad luck. I barely knew how to do an oil change but built my LS; even cut my own rings. Almost 2 years later no issue. Banging rev limiter. Best of luck to Brian
Spray brake clean around the intake manifold if ur idle goes up u have leaking gaskets
So good to see Derek and Jimmy helping out Brian. Damn that car hates Brian! I gotta see Brian win!
