Hi, i'm from Chile and i bought an used 100km 550i with the n62 engine, tough i had some steam seals problems because of small smoke but it seems its only the oil passed service, this week a lot of maintenance its going to be done and its great to know about wynn product to save the seals!, really love this car, my 4th bmw and i really like it more than others. Very very informative video adressing important things to look for and take care of them in time. Pardon my english, thanks!!

I work in software and a big concept I’ve learned is bugs in software have a root cause. I really enjoy your videos because you attempt to explain the root cause of issues. Components fail randomly, but most the time they fail to a root cause, and just throwing parts at a car isn’t always the answer. Appreciate the videos thanks

My pleasure! I'm a C+ programmer as well!

[@boulecoq1700]

I bought my 2004 645 Ci about three years ago. After about a month the engine smoked like no tomorrow. Rings were checked; ok. Turned out to be the valve stem seals. Luckily it was still under warranty. It disappeared for a few weeks and came back beautiful. I guess I was lucky to catch it so soon after buying it.

[@TimmsBMWRepairsandInformation]

Good thing for the warranty

[@alpachlavi]

Dear Tim! Thank you for your detailed videos and advice. This helps us e63/e64 lovers a lot to keep their car alive for a long time. For me, as a non-native English speaker and non-mechanic, it is very difficult to get a good overview and to understand everything exactly. Could you imagine creating a maintenance plan that says exactly when, after what mileage and with which oils, seals and spare parts which work is to be carried out? We could then give this document to our workshop. That would help a lot and I would be happy to pay for it. Is there a chance? Thanks very much!

Amazing knowledge well put into a great video. Thank you for that! I'm currently halfway through fixing a 17 years old BMW 750i and unfortunately, I am noticing most of the usual N62 issues.

Hi do you recommend swapping the thermostat for a 90c one, and changing the radiator cap to a lower bar version

Yes, I agree with the change of thermostat to 88C or 90C - but leave the cap as it is

Been watching all of your videos they are great, I’ve recently rescued a tired 2007 116i as a project cost me £700😂 I don’t mind the running repairs, it’s the sacrificing goats to the gods of timing chains(and guides) that I don’t like. My last vehicle was a 97 RT 1100 so any modern Bmw car is a dream

[@TimmsBMWRepairsandInformation]

Thanks!

[@KhanNakash]

Hi Tim, on the gearbox, I spent perhaps a few years trying to pin point the harsh shifts. As you mentioned oil, filter and mechatronic seals are crucial to change however the biggest difference I saw was with a software update for the EGS. All the clunking and shifts just disappeared immediately. Also the solenoids have a high failure rate and so changing just the shift solenoids while you have the valve body out is also a good idea.

[@TimmsBMWRepairsandInformation]

Thanks Nakash!

I did seals, solenoids (cause I had bad reverse, bit slow) and a reset. Gear changes are smooth as.

hello mate love all your videos and the information on the n62 engines keep them coming mate. i saved my 650 from scrapping it after some low lifes put in old used oil in the coolant reservoir and luckily the oil was sitting at the top of the coolant reservoir and never managed to mix in with the coolant in the engine so i done a full coolant flush a few times and havent seen a single drip of oil in it since then and the car runs as good as new, i use it as my daily and do about 12-13 thousand miles every year and enjoy every minute and second of it, keep the videos coming mate and wish you all the best

[@davidszczawinski7712]

Stem seals along with the rocker cover gaskets and the timing chain gaskets are £790+VAT so not as bad as years before. Definitely worth to spend that to keep these on the road.

[@gotmylk]

Great advice Tim! I’ve owned a 2004 645ci for about 6 yrs now and 48k miles (bought it at 70k miles now it’s about 118k ). Two other proactive maintenance fixes I recommend on older models 6 series...one is the upper radiator hose ($95 USD) which will likely come apart at a not so ideal time and leave you stranded. The second is the right and left side Crank Case Vent Valve Breather Hoses ($59 USD for the set). Especially if you currently have the older version Y pipe that connects both sides at the center. This hose gets dry rot and brittle from the heat and will split and crack causing major misfires across all cylinders due to the vacuum leak. These preventative repairs are a must do as well if one plans to keep their N62 in good order for the duration of ownership. Cheers!

[@TimmsBMWRepairsandInformation]

Thanks for the info, great stuff!

[@JesseSalmi]

Just exploded my upper radiator hose last week from the joint and waiting for the new to arrive. Quite common part to fail and should be changed if not done in while.

[@gotmylk]

Jesse Salmi similar happened to me a few weeks back. Spent the morning detailing the car, headed out on a road trip with the Mrs.. Got on the interstate and accelerated hard to cross lanes and lost power. Windshield was freckled with water droplets so I knew I blew a hose. Exited the interstate and found the top radiator hose split in half at the plastic connection. Luckily I had a few assorted hose clamps in the boot. No tools though...so used the wife’s tweezers to tighten the clamp. Let the car cool down roadside. Then limped a few miles to the auto parts store to refill the coolant enough to get me home an additional 2 miles. Ordered the new OEM hose on Amazon and replaced it in 10 minutes. It was a crap day but it could have been a lot worse...better yet it could have been prevented had I replaced the hose at 100k miles. Ps...small metal hook tool and extra long flathead screw driver to pop the clips made the job a piece of cake.

[@TimmsBMWRepairsandInformation]

Time to check your engine mounts - when they fail the engine will pull hoses off under harsh acceleration!

[@JesseSalmi]

I also accelerated hard when the hose popped off.

I am Polish user of the E63. There is even better solution to prevent for all the seals going brittle. Replace the OE thermostate that opens up on 105 °C, to one that opens at 90°C This will save your N62 for sure.

[@chuckschreiber2365]

Excellent video Tim. Another sad issue with the 650i is the cost of body damage repairs after an accident. The aluminum components are very expensive to fix leading insurance companies to just scrap the car and paying you the low wholesale price. That said, if you do need parts these vehicles are starting to show up regularly in salvage yards. Although many of these places think they are BMW dealers and believe all BMW owners a very rich. Also mention to everyone to change power steering fluid, and replace brake fluid regularly.

[@TimmsBMWRepairsandInformation]

Yes, good points there!

[@alvintobe5566]

Hi Timm this is Alvin. Thank you for replying with this video for my situation. You stated that every oil change you use Wynn's engine stop leak for the alternator gasket. You also have the Liquid Moly oil additive listed below. Do both of these products do the same thing? If so which one is better, for protecting rubber and plastic parts of the engine.

Hey man, great video! I have a e70 with the N62 and I have 300,000km on her! At around 140 I started using 5w30 and after idling for a few minutes it would start smoking so I switched to 5w40 and it fixed that and fast track to 260 I used a engine flush fluid and after that it smoked so bad after almost every start after it cooled down. Seen this video at around 300 and never thought that would of had played a part of it so ordered a set and replaced them and like you said after 400km or so the start up smoke went away!

Drove an N62B44 (545i) for 100,000 km. The car would start in the open loop but not go to closed loop by itself. The solution was starting, driving 100m, stop and restart the car. In almost every occasion, the engine would run in closed loop then. The engine already had the known coolant leaking problem (rubber O ring wearing out causing leaks; impossible to resolve financially) but it did not get worse. Refilling coolant every 4-6 months was sufficient. It would sometimes blow some smoke upon driving away after idling for more than a minute. But this was occasionally. BMW = oil leaks. Valve cover, other areas. It's a marriage, those two. Gear changes were rough when cold, but nice once warmed up. I never had the gearbox flushed. Now driving a B58. It's more modern, faster and efficient (and no restarting needed), but I do miss that V8. It was worth the trouble.

Thanks! I'm using Wynn's only at the moment

[@ENERGYCORP]

Best explanation ever! Thanks. Really love my n62.

[@TimmsBMWRepairsandInformation]

Thanks and glad you like it!

[@forzaferrari9912]

I own both 650i and 116i as my daily. I feel... well, weird now.

[@TimmsBMWRepairsandInformation]

You can be both indignant and superior at the same time then!

Thank you so much for this video I'm sure you saved me alot of money!

Glad I could help!

I have one job here, its bmw 750i. Gearbox mechanically works sometimes perfect but sometimes randomly comes up on dash saying transmission fail and car goes into limp mode. Done the oil change but still the same, could this seal be the problem?

[@TimmsBMWRepairsandInformation]

There are a few reasons why you get TRANS FAIL-SAFE PROG, the seal could be one of them, but have a watch of this: kzbin.info/www/bejne/ZqvFmaGios-Leac

[@chuckschreiber2365]

Tim, any opinion on replacing the stock 105 C thermostat with a 90 C one. A decreased heat load would also seem to extend the life of the various seals.

[@TimmsBMWRepairsandInformation]

It is certainly worth reducing the base temperature - and 85C - 90C is perfect

[@naeemyamin4925]

Fantastic Timm. Top man

[@TimmsBMWRepairsandInformation]

Thanks, and always my pleasure!

[@accuracychannel.7242]

I did an oil change every 4000km except during the break in period when the car done its first 2000km but still the smoke came. used Castrol edge 5w-40 till 60000km then edge titanium till 120000km. changed it to shell helix ultra 0w-40.

Great video!

Had a 645 that smoked like crazy. People loved to tell me my BMW was smoking lol.

[@iiirydeblaithiniii6185]

Dear Timm, I've recently encountered an issue with my right window (E63 650i 2009). It doesn't work anymore as I use the window control panel. I then went to a local triple A service center and they stated that it was the window motor that was broken. After they put everything back on, I went back and forth several times to the service center to fix the follow-up problems they brought me such as a the right door was not installed correctly (there was a big gap between the interior and the door cover), airbag mulfunction, speaker not working, and etc. Most importantly, the right window air vent was shattered due to their carelessness when they installed the door interior (the little air outlet that is adjacent to the window and the triangle speaker. It would be easier if I could sent you a picture and explain). They now told me that they are looking for the part name for several days, but I don't trust them anymore after all this and I want to attempt to replace this part by myself. However, I couldn't find the part name/number of this specific plastic air vent anywhere online. After viewing several videos of yours I can tell that you have real knowledge and passion of those BMW cars. So I comment here to see if I could get some information from you. Do you know the part name of the air vent that is adjacent to the door windows and where can I order it from?

[@TimmsBMWRepairsandInformation]

Good to hear from you! Yes, the best place to buy new is obviously from BMW, trim parts are usually pretty cheap. But, also try Ebay - there are loads of breakers for the 6-Series. To find the correct part use RealOEM, here's a link to a 2009 E64 trim parts: www.realoem.com/bmw/enUS/partgrp?id=EA52-EUR-06-2009-E63N-BMW-650i&mg=51

[@iiirydeblaithiniii6185]

@@TimmsBMWRepairsandInformation Thanks! I found the part on the website you gave me.

[@jasoneyes01]

Thanks Tim. My E70 has the 4.8 also. I drain the cooling system from the radiator once a year and refill. Change the coolant pressure cap with oem 1.4 bar ever 4-5 years. never had a cooling system problem in 13 years. I recently started using a quart of oil between changes(8000 miles). I added Lubromoly Oil saver with oil change and no more consumption.170000 miles on the odometer.

[@TimmsBMWRepairsandInformation]

Good tip!

[@davidredmond932]

Tim I like your videos please do more. I also own a 2007 650I and love it. Have you tried Wipe New on the black plastic parts

[@TimmsBMWRepairsandInformation]

Thanks! I'm glad to report that the Teak Oil and Maguires seems to have done the trick!

[@Bighardbass]

Hi Tim! First of all, thanks for great videos indeed, i really appreciate the videos you make since i'm looking out for such a car. I've a question: I'm about to look on a 2007 BMW 650 where everything looks good except some of the service intervals made on the car. it's serviced with new oil -08, -09, -10, -11, -12, -13, -14, -17 and -20. Would you consider it be a major thing to look out for? The total mileage on the car is 56.000 miles. The car has been driven 5000 miles between the oilchanges -14 to -17 and 4000 miles -17 to -20. I would really love your opinion on this. All the best,

[@TimmsBMWRepairsandInformation]

I would certainly go and look at it and leave it idling for a while - you could well have found a good one - and Thanks!

[@SwartFlowers]

Which engine is the better one on these 6 series 630, 645 or the 650?

[@TimmsBMWRepairsandInformation]

The 650 V8 is the most powerful, the 630 is the most reliable, and the 645 is the worse of both worlds!

[@setogatto]

Hey Tim! I've heard that the engines which those problems occur with more frequency are the 4.4l ones, rather then the 4.8l because of the oil cooler... Is that true? I'm thinking of buying a 650i from this era, so it would help me a lot if you could help me with that!

[@TimmsBMWRepairsandInformation]

Yes, they certainly have a better reputation, but I am not sure the truth of it!

[@arunprasadh1929]

I know this is 8 months late, but I have E70 with 4.8L V8(N62B48), and all the issues that Timm outlines in this video are applicable to my engine as well.

[@blackamile3168]

Hello timm love the knowledge you give to us about our BMW's I'm in the u.s and would like to know were do I get forte valve seal conditioner from

[@TimmsBMWRepairsandInformation]

I had a look on Amazon but could not find it - try the search "forte seal conditioner usa" in your web browser and you should find a supplier....

[@biggie_d298]

Wait 18,000 miles? So what if i did it every 3,000 km with some cheaper sybthetic oil?

[@SauceBabyP]

@Tim question for you! I have some throttle response issues. I did some research and heard its the VANOS Solenoid that could be causing this. when I put it in sport mode its not as bad and sometimes goes back to being punchy on the throttle. Any ideas how to fix this?

[@TimmsBMWRepairsandInformation]

I'm afraid that is standard operation - when driven gently the DME assumes a lazy control over the engine power - once you have giving it some welly it wakes up and responds to throttle much quicker

[@SauceBabyP]

@@TimmsBMWRepairsandInformation Interesting thanks for that Tim. I never noticed that delay in throttle response before. I also notice when I put it in Sport it becomes snappy again and has no issues. I have oil leaking all over from my valve seals and my local guy said we should do a BMW engine maintenance where he drops the whole engine and take care of the leaks. Either than that I love my 645Ci. Just put Magnaflow mufflers and love the sound. Plan to keep this for life so I want to get it right. I do 5K oil changes with LiquiMolly 5-30. I want to refresh the spark plugs as its at 170000kms now. BTW thank you for your videos on this car your a legend!

[@mikesherwood5497]

Just bought a 2007 550i E60 with 95,000kms all good but yep oil leaks... getting all sorted.... what oil do you suggest for future use and changes every 10,000ks thereafter ?

[@tjkoko2001]

If u already did oil gaskets well too late for my advice but from my own experience i wish i would have taken the whole engine out and reseal the whole thing including valve seals and secondary air buildup rather than deal with each item as ir came up, probably would have been cheper

[@gudmundurjonasson1334]

Hi,i use green bootle from casstrol 5-30pstop start

[@TimmsBMWRepairsandInformation]

That should do the job!

[@BAC_Mono]

Tim, thanks as always for a fantastic resource. I've followed your advice and kept my 2007 650i in good health plus saved a ton of money! Could I ask your opinion on timing chain tensioners? My car is on 103K miles. It's always had regular servicing including oil changes every year with the Castrol FST (changed on time and not waiting for the iDrive to recommend it.) I've also been gadding the Wynn's in recent years. That's kept my valve stem seals in good shape with no leaks (yet!). Would you advise getting the timing chain tensioners replaced as a safety measure though, or is that going too far? Thanks as always.

[@TimmsBMWRepairsandInformation]

My pleasure Doc! The chain tensioners don't usually need changing, they are very robust compared to those on the M62. The only time I would change them is if there was varnish everywhere in the engine - but if the engine has been looked after then no need.

[@tbitsilly3497]

What's your opinion of liqimoly oil in the Transmission

[@TimmsBMWRepairsandInformation]

They make excellent products - if they specify it for our cars then you can be sure it will be fine

Hi Timm. The spark plugs on my M54 engine (530i) need replacing and I am bewildered by the choice out there as well as the plethora of 'alternative' opinions on which make is good and which is not! Your previous advice on how to fix my front wheel shimmy proved invaluable so I wonder if you dont mind doing something on spark plugs for our various engines? Many thanks!

[@TimmsBMWRepairsandInformation]

Thanks and good to hear from you! The correct plugs are BKR6EQUP - these can be bought anywhere with loads on Ebay!

[@andrem7718]

In all fairness, having owned Land Rovers. I’m institutionalized to expect oil leaks.

[@TimmsBMWRepairsandInformation]

Me too - I've had 7 V8's in a row, and they all leaked - but the N62 gets first place!

[@RichieRich845]

Castrol Edge is the best oil you can use, I use on my 3 cars and two of my friends cars. I couldn't find any information online to see what additives is in Castrol Edge, do you have any?

[@michaelmcdonald9177]

Hi, great video! How many tubes of the forte conditioner do you recommend? Mines started to smoke, I’ve changed the PCV valves that were bad (after watching your video! So thank you very much) and it’s still smoking but only after idling for 5 minutes, short idles it doesn’t smoke, hopefully catch the seals before they break down to much... and do you add 1 or 1.5 cans of Wynns at every oil change?

[@TimmsBMWRepairsandInformation]

Well worth a go with the Forte seal conditioner, 3 tubes for the 4.8Ltr engine! I just use one can of the Wynns

[@mhsurfer6713]

Great information, thanks Tim. I’ve a 650 and 540 with the M62TUB44 engine so lots in common. My 650 has done 82k with no problems with either the valve seals, or alternator bracket so maybe my investment with good oils is paying off. I’m currently replacing oil at a max of 2 yrs, at 2kmiles per year. Do you think adding a can of wyns at the end of year 1 be sufficient? I didn’t know the oil or water had special seal preserving additives so that’s really interesting. I’ve just pulled my 540 apart to replace vanos seals at 84k. I know this engine has had synthetic oil from new and the engine is unbelievably clean, just like new. The water ways too! In contrast my previous 1998 M62 535 was only run on semi-synthetic and that engine had a horrid orange tint. So many thanks for the info. Long live these V8s, and thanks for sharing your knowledge. 👍

[@TimmsBMWRepairsandInformation]

Bunging in some Wynns will certainly help at any time!

[@Erik-sw8wm]

Hello Tim thank you for the great videos. I have a 2008 650i here in the states. Very clean car has 70,000 miles did a lot of work on the engine, valve stem seals, various gaskets etc. my problem is the car bucks and has a slight hesitation when you floor it from a standstill or moving. If you go easy on the gas pedal it has amazing torque and power. I have read many theories and I believe I had the mechanic clean the throttle PCR valves. It did improve acceleration but did not fix the problem at hand. Any suggestions would be greatly appreciated
