Dude I cannot stress how well you've recorded this video, it was very easy to follow along, hopefully it's not too hard in person
Thanks changed xi front diff in process I found broken oil hoses and also the disa piece that was in your video.killing 5 birds with 1 stone .
6:39 :D how many times that has happened to me... hahah
“Iiiiits a freakin miracle” I hear you man xD every hose in my engine bay is brittle at 200k miles
Hi mister, I've an N52 too, and started make a strange noise from the front part of the engine, passenger side, it's like a ticking noise...i've posted the video on my CZcams channel, what it can be?
I can not believe i did not see you video, when i was fixing the purge valve ,
You have a new subscriber, thank you,
MY QUESTION TO YOU WHAT WERE THE SISTOMS YOU HAVE,
AND CODE ,
Help please i have E60 N52
Rough idle when warn 6500rpm , just a vibration and zoommmm sound, also reverse and stop signal and red light , when driving is a smooth,
I have change the purge valve (P0444) sparks plugs, coils, solenoids (vanos ), and still have the same vibration now i have 3 codes
P2098 (POST CATALYST TOO LEAN BANK 2 ) AND SHOWS TWICE SAME CODE AND P2272 o2 sensor signal stuck bank 2 sensor 2
And a lot of forums says is these the visa ,
Can you help me please i so frustrated, of keeping fixing these car has 150000 miles
Thank you in advance
Nice
Make sure that you find the steel pivot pin that fell out of the DISA valve. Mine did the same thing, disa valve came apart but the steel pin went into cylinder #5 and punched a hole right through the piston and fell into the oil pan! That's an automatic new engine!
Found it just above the plate that covers the pistons from the bottom of the block. Removed it. I managed to fix it without buying a whole new engine. Kept the steel pivot and piston
You don't have to remove the intake manifold. Just move the alternator out of the way. There's plenty of room to remove the small Disa from the "inside" of the manifold. I've done this at least twice.
Hi, Jeff. don't have to remove the manifold? Thats good to know! now the question for me is how to remove the alternator! I have a 2007 530xi E60 N52 - i hope NOT removing the manifold still applies. if anyone knows of a video for the alternator removal i would appreciate it. This was a great video and thanks!
@@doogiehowser1124 did you find any help on removing the alternator ,
I have to remove mine because of the house from the vacuum pump broke , fucking bmw, all plastic mothers fuckers, .
How did you remove the second disa valve? Did you have to unscrew the 1st disa valve outside the manifold?
Small Disa valve has it's own set of screws to be removed without the need of removing the Big disa valve
@@N5XGaragethanks, ended up following your process. Should've just done that from the beginning shortcuts turn out longer.
Ended up finding the big disa flappers in my cylinder 6. No wonder I was never able to fix that misfire. Luckily these thing run big
I puzzled it back together to see if anything was missing and looked completely snapped in two pieces. Hope this clears it, I won't find out till tomorrow.
Thanks again for the video man! Really appreciate it!
How do I put new disk valve on
Verify that you have the stage 3 intake manifold. Only that one uses the Disa valves. It uses 2, one in the outside near the throttle body (big disa valve) and the other one on the inside side (small disa valve).
@@N5XGarage I guess it's a stage 3 found broken disa piece in engine valve hole
@@riciodarenagade Same thing that happened to me. Did you find which one broke?
Is that the stage 3 intake?
Correct, stage 3 intake manifold
So DISA failure on an N52 is NOT catastrophic, is that correct?
In my case yes, in most cases, not as bad
@@N5XGarage Thanks! What mileage did yours fail? I'm at 90K.
@@oumaniac mine failed at around 80K Miles,
Not sure but I suspect the steel pin goes down inside its hole and allows the flap to get out from its place then the pin can fall out of the hole and sucked by the engine. Otherwise the pin cannot get out since it’s held in place by the wall of the manifold.
But usually it fails to work before the pin gets out.
How did you know the disa failed?
Heard a really weird noise coming from the intake side before the engine started misfiring. More info on that on the following video
You may not have any warning (or very little warning). I started the car and heard rattling, wasn't sure what it was so shut it off immediately. Waited a few seconds and attempted to restart. As soon as it restarted the steel pin from the large Disa valve was sucked into the #5 cylinder and punched a hole through the piston and fell into the oil pan. The head was also damaged to the point that it had to be replaced. The walls of the #5 cylinder were scratched badly so I needed a new block. In other words, a total engine replacement! My advise is check/ replace your Disa valves if you have any codes related to variable intake or have over 80k miles.
@@jeffdoughty1256 RIP
Don't know yet the piece was found in the car back valve hole not at car yet
On mine, the bolt that holds the disa flap inside went inside cylinder 5 and damaged the piston. More information on the on the next upload
@@N5XGarage I checked pistons looks fine .lucky me
You dont need to take off manifold
Air flow director stuff WOW.... Once I heard that thumbs down ,obviously you do not know what you are doing....hope you don't ruin that engine
shut up dude
