Came across your channel just now, clicked because v8. I regret nothing
Wow this was an excellent video. I always wondered if the 4.6is motor would work in an E38 and now I have my answer. GREAT STUFF!!!!!!!!!!!!!!!!
Nice work Ed. Some notes from my E38 ACS.
When I got the car some 6.5 years ago, it was smoking like a champ! I diagnosed that the black oil separator inside the timing cover was blocked, and far too expensive to replace. So, I bypassed it the following way;
I fitted the X5 rear CCV which as you know breathes externally and doesn’t use that valve
I had a machine shop mate me an alloy dolly to block the pipe that leaves the oil separator to the inlet manifold which seals the pipe off
I then took off the near side rocker cover which has the external breather casting on it for the X5, on my E38 it had to be drilled out
I then fitted an external oil catch can near the steering reservoir and bought 19mm ID silicone piping
The camcover now breathes into the catch can, and the other end of the catch can breathes back into the X5 CCV at the rear of the inlet manifold
Job done. It’s been over 6 years now, and it’s lovely. Only in winter with moisture do you have to empty the catch can every 3 months or so due to water vapour
The piping I have used is all Matt black, as is the catch can so it looks almost stock
You also have to use a dremel to cut off the corner of the M62 noise cover to allow the silicone pipes clear access as they come out
You’ll need some jubilee clips, and potentially some 19mm barb plastic T pieces from plumbing supplies (depends how fussy you are with the piping layout)
Hope this helps, certainly saved my car for me, and now it doesn’t run crankcase gases into combustion which is always cleaner
Damn..so u left the old breather still inside the engine? Im guessing if it works why not 😀
@@The777Garage yep, still sitting there under the timing cover! I’d love to see how blocked it was, it was enough to not let the oil drain back to sump and pull the oil into the intake manifold!
When you do my vanos units and chains, we can investigate then
Nice to see this video! A big thanks to you .
excellent keep the good work up i bought a e38 728i and my son cant stop driving it lol he also bought a e39 525i and put some wheels on and alpina stripes but will let you know when its done .
reminds me of the Duratec 3L to 2.5L SVT top end swap, this one is more involved, but much easier as there is no custom parts to be made.. still have nightmares doing that swap.
I was gonna do that oil separator change myself on my M60B30, but now when i see it is acctualy behind the tcg and both front covers have to come off, im gonna rethink that one...
Wanted to do a m62tub46 in my e34 touring, but ended up doing the m62tub44 instead because I couldn't find a wrecked 4.6is anywhere. This should be awesome! Looking forward to seeing it.
Indeed hard to get decent 4.6 now days
5:35 Using the Milwaukee to remove the Harmonic Balancer Bolt. Just a year ago I tested the Harmonic Balancer Bolt on a Toyota 22R 1980's that I knew had never been removed. I put a 1/2" 3 foot breaker bar on it with a 4 foot pipe extension; ended up breaking the breaker bar head. I tried the big Milwaukee without any luck. So I tried 5 minutes of heat with a torch - then tried the big Milwaukee. The bolt still fought me but the Milwaukee after the heat finally removed the bolt; man oh man.., what a bear. Your fun reminded me of that 22R moment. From Texas and Enjoy your vids. Thx for taking the time to make them
Jesus bolt! lol
Fantastic project mate. Had a B10 4.6 a few years back, headgasket went on one bank, when I was stripped part of the cylinder wall between two of the cylinders had a chunk out of it... Scrap engine. I tried to find a alpina or x5 4.6 engine for ages (bought an alpina one but it turned out to be a single vanos version from the early e34/e36 alpina b10s, so fingers burnt yet again) and in the end scrapped the car, I read the x5 is a stronger engine as has metal headgaskets, 4.6 is a cracking engine
In one of my videos ive meant to repair e39 v8s alpina 4.8,after ive took head of turned it was to late as for repair as it damaged the bore..im assuming 4.6 would have bigger chance of failing head gasket than 4.4 as bore is 1mm bigger and obviously wall between cylinders smaller and that’s the weakest point same as on e46 m3’s...should have actually done head gasket job before swap..ohh welll
@@The777Garage I should have done my headgasket too, on checking the history one bank had been done with the upgraded metal X5 headgasket and the side that failed was the original. Shame your 4.8s engine had had it, I bet both the B10s would be worth a fair bit now, keep up the good work with the channel, there's nothing better than 80s and 90s BMW's. Cheers james
I did this swap in my e38, but with a G420 and I kept the external breather system. Well worth the work. And yes you have 2 options for the DME.
1. Swap a dme from a e53 4.6 is or from a b10 4.6
2. Flash the DME with 4.6 parameters.
Молодец, золотые руки👍👍👍
Excellent video. Love the M62tu when well sorted.
Exactly my thoughts
Another great video!
I've been thinking about doing this to my e39. Great content! I'll be watching.
Love the info your share about dirrence from the engine type and what common and dirrence on them
Great quality time watch you at the work
This is a cool swap. Love your videos and your work man😄👌 You are a very skilled mechanic🙏
Cant wait for the Alpina too😍 Greetings from Norway👍
Woohoo, at last 😍😍
very interesting episode
Brilliant mate! Good progress
Sweet glad it’s finally happening edd
It’s awesome how much this channel has grown since it’s start. Congrats on 6k subs & good luck with swap! 💪🏻 waiting for pt. 2
Great job, very well explained! Looking forward to your future videos!
Bravo and well done! Keep up the great work!
very informative, tks
Incredible as always 👌 keep going bud 👆
You better check piston compression
Are you going to mate this beast to a 420g?
Fantastic content, keep it up.
Now, to find a 4.6..... hard to find in the States.
I thought these V8s have a coolant pipe that goes from front to back within the valley ? They often leak ? Or is that just on the 4.8s?
Yes they have pipes underneath intake,but m62 doesn’t have that problem the newer generation N62 has that problem
Great project Ed. What will you do with the engine out of the 740?
Unfortunately its already dead
Any changes to DME? Will it still run on same factory settings?
Ill swap the ecu kit..will explain in next episode
Good job , interesting swap, but why you don't swat 5.0 or you want 8 cylinder ?
This is for me easy straight forward,plug and play swap..ill be happy with 345bhp for normal cruiser
@@The777Garage i see you put a charger in one of other your project, is it will stay alright on that normal cruiser ? :D
Do you have to reprogram the ECU or will it handle it?
It will be swapped..check out next episode I’ll explain
@@The777Garage I will thanks
What is the H.P. on a 4.6. Wow, that's a lot easier out of the car. From so. California
345hp
You work awesome! Why don't you clean and organize your shop?
I actually do..but sometimes got carried away with work
Brother where are you from
my engine beter
