You might want to look into the vanos pump failing. Symptoms: "Some of the first symptoms of a Vanos problem in these creatures is a knocking noise in the cam hubs when cranking it over. Other signs include jerky power at low RPM and a gentle knocking sound coming from the front of the heads while running"
In a world where people can watch experts put anything in anything, I'm perfectly happy to watch driftworks side projects come along at a real world pace. Just enjoy the ride 😎
That knock when cranking is the vanos hubs , your vanos solenoids are leaking the oil back down or the accumulator on the side of the block is leaking past and not holding pressure
I’ll also say it won’t actually hurt it phill it just sounds crap ! There is a vanos bleeding procedure on the stock dme with holds the revs up and swings the cam timing about to get any possible air out of the system Your car will eventually expel any possible air out of the system once driven and the vanos is activated and id assume it won’t be quite so picky over cam timing as the stock dme which is what the bleeding procedure was originally designed for as the cars would have a total melt down if they couldn’t accurately target cam angle 😂
@@driftworks If it has had the pan off and has not been running since, the internal vanos line may have not been torqued up properly. This is another consideration (don’t ask me how I know 😂)
Get a vacuum cooling filler. Especially for bmw’s a gamechanger. Makes filling much easier with less chance for air pockets and its a nice way to test for leaks
Going to be really interested to see what you come up with to keep the under bonnet temps sensible and prevention of the coil packs being melted by the manifold.
@@spazda_mx5 Totally agree as can see some form of fire starting at some stage sadly due to the intense heat the manifold will generate and the lack of cooling ducts in the bonnet etc.
@@stephenreed1080 stainless steel tube grows in length a lot when it gets hot…. You see it sometimes when TH-camrs video exhaust noise with a camera focused on the exhaust tips, every time they accelerate the exhaust tips stick out by a few extra inches 👍
@@boost3d831 Nope… if that’s the case the torque reaction from the engine is pushing forward so the exhaust would appear to shorten… it is definitely tube length growth… 100mm of stainless tube grows by approximately 3mm from room temperature to approximately 1000’C so 4m long exhaust grows a lot in length!
I'm glad you guys picked up the knock during cranking. I heard it last time and I was going to mention it. I would tread very carefully until you know what's causing it. I'm not familiar with the VANOS in the S85, but in the S54, there is an accumulator that can sometimes fail. IMO, this doesn't sound like a VANOS knock., but if you want to see if it's operating properly, there is a VANOS test in DIS for the S54. Perhaps it's the same for this engine.
The knocking sounds like the VANOS hubs rattling until theres oil pressure, would definitely be worth testing the pressure from the vanos oil pump and also test the accumulator, a failed accumulator will cause low oil pressure to the VANOS on start-up.
@driftworks No worries 👍 there is also a bleed procedure for the VANOS system with ISTA but I'm going to assume your ECU won't support that, but it may be worth seeing if there's a way you can manually bleed it
Admittedly this is my first video of the series. It looks crazy but I can’t stop thinking about the inevitable valve cover gasket failures, the complexity of standard maintenance on the engine, the excessive introduction of high heat environments from the manifolds. I don’t know the expectations of the usability of the car, but I’m seeing a sema build rather than a weekend cruiser. Looks dope though.
Without actually being there, When i first heard the knock when first cranking sounded like it was the engine rocking on cranking and hitting something especially looking how tight a fit the engine bay is
Have you guys bled the vanos since the rebuild? If not then that vanos knock on turn over will go away once bled but bleed it 2 or 3 times one after the other it takes 18 or so minutes per bleed then reset adaptations and run a vanos test and see what numbers you get. Also vanos solenoids can play up if left to sit a while they can be cleaned/checked using a 9 volt household battery and change the seals to viton ones as std bmw ones perish. The knocking is just air in the vanos system
Vanos needs bleeding. There is a test plan on bmw ista that opens the solenoids at incresed idle. With your stand alone, can you activate them to help bleed them out ?
Maybe you need some roll in counterweighted plank type deal to lie down on while you do your ITB set up mate to keep you away from the monster exhaust haha
Sounds properly knocky on startup - is that something in the Vanos knocking without oil pressure? Doesn't sound like bottom end. The mic can be a bit deceiving though too. Ah you just mentioned it! The mercs have a locking pin on the cam variators which fail & causes the same sort of noise
@@driftworksAs far as I know, the throttles restrict the airflow - 6x! - that's why we changed it on our bikes after 1985! I don't know, but I thought this was more common in the US - maybe it's too complicated and time-consuming? greetz from AUSTRIA🤠🥳

Zircotec for starters
@@Hybridesque Absolutely but Zicrotec alone is unlikely to be enough especially under track day use.
He's going to have a laptop on the car to tell him, DANGER TO COILPACKS...... 🤣
I think I'd plumb a fire extinguisher in there too.
@@spazda_mx5 Totally agree as can see some form of fire starting at some stage sadly due to the intense heat the manifold will generate and the lack of cooling ducts in the bonnet etc.
30 seconds after each fire up, you can see the manifolds very visibly move and arch up as soon as the get warm.. hope they don’t crack 🙏
I thought I could see that too but wasn't sure if it was trick on the eye

@jamest5149 that's nothing to do with heat, that's the engine mounts compressing under load
@@boost3d831 Nope… if that’s the case the torque reaction from the engine is pushing forward so the exhaust would appear to shorten… it is definitely tube length growth… 100mm of stainless tube grows by approximately 3mm from room temperature to approximately 1000’C so 4m long exhaust grows a lot in length!
@@jamest5149Its the mounts while yes they do expand and grow that's not why the exhaust tip moves its engine torque and rubber mounts move.

@@Invad3rsMustD1e Late response, but I'm fairly certain the bleeding procedure is just swinging the cam timing at a higher rpm until air is all out
Lovely to see you and Vitten making sounds.
That knocking sound is vanos related. Check your pumps/solenoids and pull the vanos unit to inspect that everything is in good order.
Good to see some progress on the V10 M3. Hopefully that gives you and Jay more motivation to keep at it. Sounds sick.
Have you considered trying big cams like schrick 296/284? That'd really make it sound crazy in conjunction with those headers I think
I physically can’t wait for updates on this build 🥵

“I’m just gonna tidy it up” ….Pt. 50 😂 gotta love Phil!
😄
So happy to see these videos coming thick and fast on the M3 ❤
Keep it up guys, love the motivation! Real step forward, keep going, keep the videos coming we all love it!
"What were you doing cooking?! That's not like you!"
"Pizza" 😂
this is the most beastly looking e46 EVER. LOVE IT
This is going to sound insane on full chat!! One Question, what are you going to about heat management? That manifold is right next to the intake!
Looking forward too seeing how the intake temps are kept down.
@m539 restorations could diagnose that knock noise for you
Without actually being there, When i first heard the knock when first cranking sounded like it was the engine rocking on cranking and hitting something especially looking how tight a fit the engine bay is
Having felt similar pain, the vanos pump was my devil
Possibly vanos knock… I had the same noise from my M5
Thanks man. I have my suspicions it's that too.
Holy Grail V10 Headers in world 🥇💪❤️😁
Hello master ,
This is the best and craziest build in the best engine v10 for ever
In the world ,, beutiful , and speachless bro ❤❤❤❤❤❤❤
Its sounds like sportbike like yamaha H2 stock , wow man ❤
Absolute machine
Missing some D&B but starting to sound about right :D

This thing gonna heat soak worse than the 1st wave of C7 Z06’s 😆
This time next year Jay.....we'll be drifting........ 🤣

Thanks man. I'll look into it 👍
Silly question Phil but with a complicated cooking system with lots of pipes and rads why not just vacuum fill the system. ?
12:32 something about to enter a throttle body 😮😮😮😮
That's what Jay was onbout when we shut down.
When cranking you will hear a "crack", this is the vanos and is normal. Happens to every S85 I've ever heard.
cant wait to see the intake design with all that hot air from the fanny moulds right there ....
Maybe you need some roll in counterweighted plank type deal to lie down on while you do your ITB set up mate to keep you away from the monster exhaust haha
Forklift is always good for that. We've been there with the Lambo before 😄

sounds great
I’d happily be as amateur as you guys 😊😊
Interested to see what you come up with for intake/air box, as to not being sucking hot air into the engine???
What was the fix in the end you lads never mentioned it??
Multiple things, but the biggest issue was the exhaust blow on a few cylinders.
6:00 it sounds like a two stroke
mee too !
Sounds epic fellas 👌🏻 what’s the oil pressure at the right hand vanos ? Loading slow ? Filters clean ?
Its a shame you can't have an electronic water pump and oil pump. Being able to prime to get pressure before the startup
There’s bound to be some heat in below that bonnet
After it Fixed Please Make Video Full Send under A bridge or Tunnel 🙏❤️😁🙏😊
What is that handheld flow meter?
Fully built V10 screamer inbound?👀😍
v10 is winning the battle so far! haha Loved this car when you first built it long ago. The forum days!
Sorry if I missed it but what did you do to get the back cylinders working? Love the progress
you didn’t miss it… we all missed it
I pulled the plugs, cleaned them and put them back in. We're not entirely sure it's fixed, but it's getting better every time we mess with it.
@@driftworks get yourself a thermal camera you will be able to tell instantly which cylinders are down plus blocked rads etc
@@eliotmansfield@8:00 they are doing exactly that
@@eliotmansfield They have a heat gun in this video
Those headers going to damage the bonnet?
she'll never run super smooth till you get that belt on it. the alternator makes a big difference on idle
The belt is on. The altenator is running and the car has 13.8v at idle.
why no slider instead of a throttle valve ??🧐🧐
Why would I want that? The ITBs are standard S85 parts.
@@driftworksAs far as I know, the throttles restrict the airflow - 6x! - that's why we changed it on our bikes after 1985! I don't know, but I thought this was more common in the US - maybe it's too complicated and time-consuming?

You guys need some welding sleeves to work on this car 😂
Pulley solenoid ?
Vanos springs 🤔🤔
Well done guys.
Rattle... Ask Sreten at #M5E39
I think under hood will be very hot and it's not good.
and you have a lovely spot to put a kettle in the middle of that collector
Sounds like vanos system failure.
I still think this is just the strangest set up and makes absolutely no sense.
100 😂 Comment ❤
thermal barrier has to be put on those coil & vale train cover before it start to make any pull🤣
