I have never been so nervous watching a tear down video, lol. Glad the bearings look good. I'm honestly shocked that all that metal was contained within the pan and there wasn't any additional noise from the VANOS. I was not expecting that debris field in the pan at all. Insane. I'll still ask about the engine though to see if I can verify if it was replaced.
Like i said when we picked it up, the best thing is that you will get to see what was wrong and not have to fund it lol, we will post again tomorrow, i wasnt happy with the focus on the camera without phil being here to control it, but i have some more updates on the vanos hose and alternator .
@@NathansBMWWorkshop Got word from my buddy. He's not aware of the engine ever being replaced. When he bought the car it had around 40,000 miles and had been damaged on the front right fender.
Someone probably rotated that engine backwards (which can cause that exact issue on the vanos pump when there is pressure in the line - splits the bearing race). I never park S85 cars in gear as something as simple as pushing the car in the wrong gear can rotoate the engine backwards and crack the vanos bearing race. On a manual car this could happen very easy if you are in first with the car on a hill (not running). If you roll it back and let the clutch out you have rotated the none running engine backwards a little bit damaging the race.
Good video. That's similar to what I found in my pan. Btw internal gears in the regular oil pump were scratched in my case, so I replaced it as well. Good luck with bearing measurement!
Yeah - BMW's always leave you a present. When I did my rod bearings I found a bolt in the pan, a broken upper and lower rod bearing on #1, was wondering why it was rattling when it got to temp, and the usual oil leaks and snapped oil pan bolts.. Once fix she's a dream. I expect other issues but otherwise it's sound and safe as I did the work myself - like you. Hoping you don't have to pull the engine.. Great Content bro!
no suprise if same rod bolts put back some time past. true if that debris was run thru the motor rod brgs would show it. possible to push up a piston to mic jounal? you da man to make something of lasting value/save this car
Hey Nathan ,would you recommend AT205 reseal for BMW X6M gasket and valve seals leak ?? Will this product harm the engin or worsen anything else in car Please let me know
IM FIRSTTT, Had a feeling the car was gonna have a serious issue due to that vanos code, whenever a s85 has that it’s always a good idea to run away unless you get the car for price of a 95 civic
My stomach was turning as you were going through the rod bearings one at a time. Then when you said the last one might be the one I basically died cus I thought you cursed it!!!!!! Don’t say it out loud and it won’t happen 🤣 . The CLOSEST os close calls ! God I can breath now.
E60 M5’s are notorious for rod bearing problems from the beginning, Nathan with all your experience, you must have known this, a monster of a car no doubt
Is there a good reason not to use factory rod bolts when replacing the bearings on the s85? On the s54 people have pretty much concluded that factory is the way to go.
The thin streaks of wear on bearings is from running with no oil due to vanos pump failure leading to oil pump not spinning. Your primary wear will be on front main bearing which you will never check in the car. Secondary, the cam journals all get significant wear when this happens. To the point of failure on most which takes out the cylinder head. I would recommend remove valve covers and check each cam cap one by one for wear. Torque back down each after checking. Don't remove all at once or cam will get loose.
The passenger valve cover is leaking , i believe from someone removing it so i will check the cam journals when we do the gasket , After we pulled the crank snout gear off the tooth wasnt missing it was crap stuck in the gear , so i believe it was turning the main pump still , the bearings would have been all gone if it stopped turning i think at this point
@@NathansBMWWorkshop I see. Best of luck with your endeavor. I'm sure we all can learn somethings from you, including myself. I've always wanted to learn about these engines.
@@troyjeup2861 😂yes I heard you just did your first build , I wasn’t trying to be a asshole I was just saying the gear was still good so the main pump was still turning , cylinder 3 and 4 top bearing were down to copper but not the bottom half, the tops looked like they had lines in them but not the bottom side of the bearing , that’s why I was screaming hard detonation , but as I’m typing this I realize this is on the older video , todays video shows everything much better and give a more clear view of what’s going on
😳this guy dropped a fractured rod cap from 5 feet off the ground, made a funny face,and states “we will put that back in” that’s all bad my man. It probably won’t seat properly with the connecting rod. Best of luck.
@@user-oj6vl8io3f Doesn't matter who owned or previously worked on it, E60 M5's are notorious for fkn up. Great cars when they behave and run properly, once they get over 3/4 year old they're just too fragile and pretty much constant maintenance if you run it as a daily.
I actually have seen people like these, I saw a 5 year review of someone who owned it and put 60k miles on it and it had 130k miles but he did the rod bearings just to be safe because the oil sample showed up with more metal over time. He used it as a daily and had the typical small things happen but other than that he was happy with his ownership
Of course for a fee, I just don't trust mechanics in my area. I purchased the car recently it's been through 4 owners, I want to completely restore it to its factory state and hopefully one day pass it to my son.
In my experience, oversize engine bearings are always stamped on their back sides with the oversize of the bearings. If they are not oversize, there is nothing stamped or they are stamped "std."
So why exactly do these fail so often? Thick oil, unbalanced rotating assembly, is there too much thrust causing them to get ate up every time you put your foot in it?
@@terencegalati970 I just stumbled on this video, but I have to wonder if the engine has been operated in an extremely cold environment. I run an N52, which is a good engine if you take care of it. I cross my fingers and cringe starting it in my upper Midwest winter mornings. I have seen -20F. I'm using the recommended 5w-30 oil, which makes me nervous. I sent a sample to Blackstone, and my engine is doing great at 152,000 miles. Strict discipline during warm-up seems to be paying off. Fingers still crossed!
S85's are notorious for catastrophic failures, and I've rarely seen them last above 100k. Racecar F1 engine technology with F1 Racecar engine reliability/longevity. Hopefully no metal fragments made it thru the oil pickup screen otherwise you can kiss that motor goodbye. Best of luck.
How is it a junk car? People didn’t do proper work to this specific one. For what this car is the work and money is worth having a V10 monster sedan. You probably haven’t even sat in one. You’ll never understand unless you drive one. Nathan will have it figured out and someone will have a manual V10 sedan that will be good for another 80k miles +
@@MrTruthAddict The E60 M5 is on any BMW aficionado legendary M car list, even with its problems. Definitely not a junk car and if i could buy a broken one for a fair price, I would not hesitate. If you make it good, no problem selling it.
BMW's are over engineered, that is why some engines are unreliable. The 6 pot non-turbo motor was BMW's legacy, but no more. I will agree with you about quality engineering in some of the engines, in particular the V8's, what a fu*k up with the timing chain guides. I drive a 330i with the N52 motor, currently 245K KM's on the clock and still going strong, definitely one of their best engines BMW ever made.
@@Shane-fk2gz loaded question. The recalls on the new stuff won't be out for 30-40 months...... but the reason you do not see E46 out there is the con rods, VANOS, rear subframe. 3.3L, the size of the 2002 M3, that's a big engine, yet they are long gone as though they were little turbo 4 cylinders...... lol.
