BMW E46 Project: The Big Delete, Part 1 (CCV and ICV delete, catch can install) 

Look for a youtube channel called Nuisance Carl. He did a turbo build in an E46, and documented the whole thing. Lots of good info there.

I figured out the fuel injector clips after making the video. LOL

Same

thanks!

I have to disagree with this. If you do that, you'll be dumping oil on the ground.

@@michaelblacktree only if the engine surfers blowby, which in that situation one would have a bigger issue. The idea of the ccv is to eliminate oil vapour venting atmosphericly and satisfy certain emission regs.

All engines have blowby. It's just a question of how much. Dumping that stuff directly onto the ground is irresponsible.

@@michaelblacktree my engine doesn't have excessive blowby which is what you're describing so it doesn't drip any oil on the ground from the breather hose. And in any case, if you look inside the oil filler cap, you might notice that you can't see the valve train ! This is because there is a baffle plate which effectively acts as a catch can only it keeps oil from escaping in the first place , and allows the top end to breath waste vapour and pressure.

@@rjhtrucking5429 yeah I did what you said and I blew a crack in my valve cover from the excessive pressure. The engine NEEDs vacuum

I'll let you know when I find out! Still waiting on parts. But yes, the ECU needs to be reprogrammed for the ICV delete. I'll cover that in the next video.

I used plastic plugs for furniture legs. I found them at the local hardware store.

@@michaelblacktree isn't it too hot for plastic in there? im afraid it will melt down

Yeah, don't do this stuff to your daily driver. This is a race car.

Just random stuff I picked up at the hardware store.

You know what's funny? Last time I removed the intake, I could have removed that vacuum canister. But at the time, I didn't know what the canister was for. So I left it there.

@@michaelblacktree Haha. I guess mine's staying for a while!

I decided against the M50 manifold swap.

It's drive by wire. I had to tweak the driver's wish table a little bit, for a more stable idle with the ICV delete.

@@michaelblacktree Ahhh. I was wanting to do the same with my car since it's supercharged. I feel the intake has some vacuum leaks. But I don't know if it's possible to make the car idle without icv on a cable throttle.

On a cable throttle body, you need the ICV. On drive-by-wire, not so much. That said, if the throttle stop is adjustable, you could fiddle with that. But it won't be the same as having a self-adjusting idle.

I have a screaming noise after deleting the ccv system. Only that I returned the line into the manifold. I have no catchcan and I hear a screaming noise from the back of the engine where this vakum valve is located along with a few more additional hole that has ben plugged up. I also blocked the line that comes from the vakuum valve. I don't know what i did wrong.. I removed the intake ofc. Everything seems to be in order but I get confused idle and that screaming noise I mentioned. Oh and also my oil preasure may go down because I get the oil warning light when the rpm drops. Any ideas? Thanks!

Are you saying that you deleted the CCV system, and just hooked the CCV line up to the intake manifold? That would be bad, because it's pulling manifold vacuum in the crankcase. If you delete the CCV system, you need to either vent to atmosphere or install a PCV valve.

@@michaelblacktree can I call you somewhere and ask some questions? I can also explain it in more detail. Thank you!

@@michaelblacktree okay so turns out installing a PCV valve in the tube solved everything. Thank you Michael!

cool 😎

There's a spreadsheet on that page. You have to copy the data from the spreadsheet into the appropriate spots in the tune. Also, after you're done you may need to fine-tune the idle a bit. Or at least, I had to.

Random stuff I found at the hardware store...

@@michaelblacktree how have they all held up ?

So far, so good. The small ports in the manifold (where the vacuum tree used to be) have rubber plugs. They're glued in with black RTV. I used chair leg caps for the ICV connections, also glued in with black RTV. That said, the MS4X website has a 3d printer file for the ICV caps, if you'd rather do that.

@@michaelblacktree awesome thanks for a quick reply . Did you ever end up throwing the idle control valve back in ?

I'm still running the ICV delete. The throttle response is so much better! Although it can be touchy at light throttle. So probably not the best for a street car.

My line seems to run up towards the blower motor area and into the firewall

You only need to plug the manifold port. The vacuum line goes back to the muffler.

The ECU needs to be reprogrammed. There are instructions on MS4x.com

Good question. Personally, I don't think so. If you want better throttle response, you don't need to delete the ICV. You can tweak the throttle response in the programming.

@@michaelblacktree Does icv need to be removed for turbo setup?

I don't think so. I removed it, because it's malfunctioning. And I'm too cheap to replace it. 😛

The MS4X website has 3D printer files for those plugs.

@@michaelblacktree do you have a link for me please I can’t find it online

That's what everybody else does. So I figured I'd do something different.

@@michaelblacktree alright i see good luck!

I got rid of a bunch of crusty old parts, and helped prepare the engine for boost.

Can someone help a brother out? If there's no response, you can try BimmerForums or E46Fanatics. They both have active communities.

Whatchu need man?

Necesita configuración de ecu???

Preparing the engine for boost. The stock CCV system can't handle boost.

I'm not on instagram. The CCV delete shouldn't trigger a check engine light. But the idle valve delete requires tuning. Honestly, I wouldn't suggest the idle valve delete, unless you're building a race car or something.

@@michaelblacktreeThank you. I’m just dreading putting the intake manifold back on since I busted so many hoses (200k miles) and I really only wanted to daily this car until the Summer (Gathering all the parts for my K-Swap), and figured if I removed the CCV it would be less of a worry later down the line, and shorten the reinstallation process? I only took it off due to starter going out.
