My 1986 BMW E28 has been sitting for ages without me knowing if the engine is any good. In today's episode we are going to find out if the engine is going to stay or not.

Just realised how much better everything has gotten since first videos, garage, equipment, editing, everything😀👍
Thanks!
Milky residue! Someone call Ethan from CarThrottle to get an expert opinion.
LOL just what I thought about that moment...
Call the milkman fast
Love your videos, the funniest one was when u f*cked up the door's paint
I'm so glad that TH-cam recommended me this channel. I'm enjoying every video. Greetings from Croatia.
Craftsmanship gone into that shed is beautiful 👌
It's astounding how fast they are bulding the garage, few weeks ago it was nowhere.
Hey man, I had a weird issue with my idle on my e34. Check to make sure your throttle position sensor is correctly adjusted. I changed gaskets, fixed all the vacuum leaks and it would not idle right. The TPS is on the bottom of the throttle body and has two Phillips head screws. It has two little contacts in it. Take the throttle body off, loosen those screws and turn the tps as clockwise as you can and you’ll hear a little “tick”. That’s the sound of the two contacts meeting. Essentially zeroing itself out. When it’s at point, lock it down. It’s a dumb design but if that thing is misadjusted, the car doesn’t know where the throttle plate is and idles horribly.
That is a nice piece of advice
@@memphis5220 I was just about to write the same,i think engine bypasses icv when throttle is anywere but resting position,you can hear if it clicks in resting position ( no throttle) with car turned off, i had the same problem on my e28 518i l-jet ( i think your 520i has same injection),basicly somebody just cranked throttle cable adjuster to give more idle speed because throttle body was dirty so to ecu it wasnt idling at all,it was part throttle
I wouldnt adjust tps if it wasnt messed with before,clean throttle body and adjust cable first,it think tps location is marked from factory with yellow paint
Man, alot of people would be willing to have that info. Irregular lope of the idle means Throttle positioning sensor. Needs calibration! Thanks!

Don‘t worry about the rust in the cylinders. Keep an eye on the cooling fluid level. If there is constant water ingress, the cylinders might have excessive wear.
Having had an E34 and an E39 you can't really beat the straight 6 in M50 and M52 guises but the M20 is still a decent engine and easy to work on. Wouldn't worry about the cylinder rust if you are planning to run it soon and to me it sounds really strong. I have a VW Passat 3C2 now and have performed much DIY work on it over the years. Impressed with your tackle anything attitude and your willingness to learn new skills. Keep it up!
0 dislikes for the beemer.. my guess is everyone wants more bmw videos ❤
960 likes / 0 dislike wow. You're doing great mate!
Interesting Video!
Personally, I think that the rust in the cylinders are not that bad.
They will disappear after a few drives but i wouldn't wait too long....
"disappear"... Weight reduction just disappearing - mmm
I think the Water in the Oil Cap is normal. My M40 in e36 does also get white slime there when i drive short distances (10km or shorter) to keep it clean you need to drive 100kms with high load. I never needed to refill coolant on the last 50k km. Greetings from Germany. You have the best Content in Car repairs. I love watching your videos ;)
Man, I had the same early m20b20 in my e28 and it too had a high idle problem. This older version has the weird vacuum system that controls idle but later models have the idle control valve which makes life much easier. I fought with the high idle problem for years, but then swapped a m20b25 in it. Nice power gain compared to b20.
Great video and good luck!
I always like the period sounding music in these episodes.
Leerzame video met een goede uitleg van sommige zaken waar niet iedereen direct iets van begrijpt. De auto loopt nu al een stuk beter met de uitlaat en kleppen die gesteld zijn (als ik het tenminste goed begrepen heb ) en zou als alles technisch oké is toch een keer de bestuurdersportier opnieuw spuiten vanwege het kleurverschil, maar weet ook dat je geen fan bent van carrosserie werk...Al met al weer een fijne aflevering en kijk alweer uit naar de volgende!
Never clicked so quickly on notification!
24mins of heaven :))
Amazing video , if it was not for covid i'd come meet , i'd love to learn some things like changing brakes etc :f
*Memphis gets in the car while still on the air*
OSHA: :O
Great as always Memphis :)
Learning so much from you 👌🏼👌🏼 Keep up the great work...
amazing video!! love to see the e28 evolve!! keep up the good work!
It is an early M20 since the distributor is underneath the inlet manifold.
L jetronic engine management which I honestly prefer. You can play with the ignition timing a bit.
You guys are great, doing a great job and lovely Videos! Subscribed!
LOVE seeing e28 content. Keep up the the good work
Great that the stickers are ready! I have just placed my order - can't wait to get it haha. Keep up the great work, hope it helps a bit :)
Great work on the lovely e28 Memphis, workshop looks superb by the way 👍
As always another brilliant video, thanks Memphis ✌
BMW is always a joy to watch want to see you work on it more :D
Great videos keep it up. Watching from Liège, Belgium :)
Really enjoyed to video, I have a 87' 528i that had a similar issue with the idle, the idle are control valve looks identical to mine and had to turn it quite a few turns for it to make a noticeable difference, in addition I'd say just replace the vacuum hoses because the ones from factory are not made from the best rubber. Also, you could try doing some fine tuning with the distributor timing and air flow meter, as mine had been sitting for 16 yrs and had been adjusted wrong. The combination of all of these thing led to it idling around 750. Finally, there is a guy in Denmark that repairs instrument clusters called Ivo Christov, as there is a battery on the SI board that runs flat if it hasn't been used. just sent the cluster to him and he will fix it for a cheap(ish). Keep up the work on the e28, it makes a great series, Luke
Yours is an M30 engine.
@@SkywalkerTibor yes, m30b28 but with a very similar LE jetronic Bosch fuel injection.
@@lukestockbridge8569 Yeah, they resamble each other, thus the problems with them do so, as weel.
Bij starten klinkt ze nogal arm in mengsel. Zit er ergens een koude start injector op? Meestal hebben deze een timer en activeren ongeveer 8 seconden lang nadat je het contact opzet. Als deze niet injecteerd kan dit ook het stationair beïnvloeden, soms werkt deze mee als stationair verrijker. Hang er eens een co meter op, misschien draaid de motor te arm. Dus overvloed van lucht of valse lucht. Mss injector seals, inlaat, bekabeling. Ook lamda sonde is mogelijk indien deze dat al heeft. Uitlaat lek aan kop flens kan dan bv ook de lamda beïnvloeden.....
It has really low mileage, so don't need to have a reason why need to replace whole engine.
Brilliant video Memphis love your BMW 👍🇬🇧🇬🇧
Great video, Memphis. Very enjoyable indeed.
Learned a bunch of new things specailly the pestone heads ideling very well done
YES back to the E28, love it, thanks Memphis, love the stickers too
underrated channel, congrats from Guate
Hello from Ukraine🖐️ Great videos man, I enjoy every minute of it. Like and follow! Keep going)👍
I'm working on the coupe version the E24 and know most of these problems first hand.
First of all get the idle screw out and check for the rubber seal. Either it desintegrated or it is just missing. Both cases will make idle setup impossible.
Get a workshop rev counter. The cluster one is not accurate enough to setup. Also I highly reccomend to start with the base setup of the engine and adjust from there. The settings are in the workshop manual. That will point out easier if anything is broken or was messed with.
Just a tip to your first no start issue. Without the air flow sensor the car won't get gas because the gas pump is enabled by the switch in the air flow sensor.
Like also how you managed to check the celenders with the camera that saved alot of time and money
Great video :)
Informative video, keep ‘em coming. I have an E30 with an m20b27. So, I’m taking notes!
that white milky looking stuff is normal unless the rocker cover is full of it, its condensation of water on the inside of the engine, all it shows is that this car is not a daily driver.
Keep up the good work on your BMW E28.
Always so great (:
Job we done. Amazed what you have achieved so far. Very anxious how it will run and looks at the end. Keep up the good work. GreetZ from Holland. Proud Golf MK3 driver
Hi thank you for this episode I m waiting for next episode I wish you a great night
Hey I'm learning some new stuff here , and I love those old bmw , I have an E36.
Great cars, great videos!
Keep it up.
I'm pretty sure that your problem is the additional air slide valve that unfortunately is no more in production since 2018. You can find the valve following the hose that goes to the idle switch that you have cleaned in the video. Bypassing it will help your idle at warm but not at cold. You might like to use a manual switch so you can close the additional air when the engine is warm. Good luck
Top om je filmpjes te volgen! Inspireert mij ook om meer te klussen aan mijn auto. Nu alleen nog een garage om in te werken :), momenteel is dat de openbare parkeerplaats.
I have a 1984 6 series. I highly suggest the M30 engine, it's bullet proof, easy to work on, and is smooth. The injector's sound is normal.
The idle is handled by the ECM to my knowledge on all BMW's in the 80's with the motronic system. On my car in my case, the only thing a throttle body plate adjustment does is make sure it's not rubbing against the throttle body. If it's too open, it will raise the idle, but it's not meant to be a idle adjustment.
Your best bet with the idle issue, check all your temperature sensors on the engine and any hoses for vaccum leaks. (oil dip stick, oil cap, hoses that may be hidden under the intake) There should be a sensor for the ECM that tells the car if it is at operating temperature. It's very common for the wire to be broken causing a high idle. You should also investigate your AFM or MAF. I think the 86's still had the AFM.
With a lot of used 80's BMW's (mine included), the last owners opened up the AFM and messed with the gear in order to "fix" idle and power issues. This 'fix' only hides the real issue and can cause more engine issues down the road.
Your O2 sensor (if it has one) may be bad and can cause high idle.
Hunting down idle issues on those cars is not fun, but don't discount anything just because it looks good! I learned that the hard way and wasted a lot of time.
Valuable comment. Thanks!
Liking your posts. A methodical approach to trouble shooting. Got my own VW Scirocco 1983 1.6 GL Auto. Based on your BMW brake refurb video I bought some parts and will do a 'Memphis' on them when I get time! Keep up the good work. 👍
Cool videos man! Very useful as I am working on my e28 (m20B27) and am now in proces of installing new control arms, bushings, coilovers and rear subframe bushings. Watching your video I am now tempted to remove the rear completely to change everything and not just the silent blocks.
Love the old beemers. Got a E21 2.0 6 cyl now. Love it👍
Great video, in fact this channel is the one which I see effortlessly all the videos end to end. This was needed to be said. As for the idle, I would connect a diagnostic software to read all the parameters. Surely that for Bosh L Jetronic there is somerhing available. Also cleaning the inhectors might be a good thing to do in order to solve this issue (injectors could be sticking a bit, leading to an increased amount of fuel delivery ) and it could reduce fuel consumption. Keep up the good work cheers Memphys
I subbed 1 and a half week ago. I'm so glad I did
Sleeve clamps or V-band clamps are all I use anymore on my exhaust systems. As well Permatex Ultra copper silicone gasket maker helps on all the rusted, pitted and slightly untrue and distorted surfaces that you are trying to seal on old exhaust systems
Great video, the E28 is the coolest car in your stable in my opinion. Really looking forward to seeing more E28 vids :-)
Thank you for this video. Very interesting. I think those compressions are very healthy indeed. The corrosion on the cylinder walls do not look serious. I think this car just needs a good going over and service and then more regular use.
I must say I really love this car of yours. When I was in high school my father bought one of these new. Also 520i Manual in Dolphin Grey. To this day after 30 years thís is the car I most regret not being in the family anymore.
Interesting, my father's car was a 1987 model with Shadowline trim, but it had twin exhausts right to the back. It sounded só beautiful.
Built by BMW in South Africa in Rosslyn factory. Did late European versions also come with twin exhausts?
I think that the next video is about the differential, I heard the noise when you came out the vehicle ! So good luck
compression test proves that M20’s (& probably m30) are solid motors with great longevity when taken care of .
Eish🤔,this Matchbox is few kilometres away from running a good lap on Nurburgring 😎.
wow you make interesting and good quality content! i subscribe.
Video is al wel een jaar oud maar mooie video weer Memphis!! Je maakt leuke eerlijke content.. groeten uit Canada.. oh ik volg M539 restoration op TH-cam ook.. hij is helemaal in BMW
Nice to meet you,
I'm looking forward to it
I'm from Japan, and I own E28 for 25 years.
never been this early, have a nice day everyone (:
Great video Memphis really enjoyed it! Hopefully you used some heat resistant paint for that bracket ;). I would make the BMW road worthy first before modifying (the engine). You have done some important things already on it. (Brakes, welding, tires, suspension, fuel system and exhaust). It shouldn't be that much more work for inspection. Inspected it, drive it and enjoy! That way you can make the best decisions for modifying it in the future!
Awesome Car! And now you're all ready for that Garret 68mm Turbo you're putting into it!! As well as the BMW "M" Limited Slip Differential you're putting in. Good choice! That will give you just the right amount of power and ultimate control required for modern motoring! LOL. Great video and thank you for making it. I can't wait for the burn outs and drifting!!
Both of your cars are awesome. You have a taste
This beamer is so beautiful,im in love
You should never mess with those icv factory settings and you need a smoke test kit for vac leaks 👍👍
Also, M20s require valve lash adjustment every 10,000 miles (22.000km.)
my bmw e30 aslo has the m20b20 engine and its sounds soo good
good video, greetings from brazil
I’m getting my hands on a -89 E34 with the same engine. Yes not the quickest, but it’s been extremely well taken care of. Looking forward to watching your video!
I don't get it why u didn't check for exhaust leaks before welding the muffler, but ur doing a great job, ur a perfectionist, just like me :)
To be fair if you want on budget clear all rust and paint. 🙂 And good luck on next video ♥️
My e28 also didn`t have a rear muffler (only straight pipe) - it could be a common issue :D
0:10 i like that sound of closing doors at my car.
Hi memphis! Greetings from Argentina! Are you going to do stickers for the golf? I love your videos!
Super al je filmpjes heb sinds 2 dagen een e28 520ia uit 82 project auto moet alles aan gebeuren en heel veel zal ik je clips gaan gebruiken super gaaf doe je het en heel duidelijk echt top
oh boooi een nieuw video 😍
Awesome video with fantastic content. How successful was the camera? What brand of camera is it and would you recommend it?
Please, do more video about this car!
Kei leuke video! Ik heb vroeger een E30 320i (1990) gehad, prachtige auto was het. Iets wat bij mij heel goed hielp was het gasklep en heel het inlaat systeem eens goed reinigen. Wat ik ook deed was, net voor het ik ging starten, het gaspedaal hele indrukken en loslaten. En dan pas starten. Voor één of andere reden hielp dat. Probeer het maar is een paar keer. Kort helemaal indrukken, en dan loslaten en dan pas starten. 😙
really enjoying this series as myself and my dad both had E28 525e models in my opinion they are the last true BMW cars
cylinderwanden uithonen is het beste dan nieuwe schraagveren in de zuiger plaatsen scheelt ook in olieverbruik
Love the Beamer
I would put swing doors on the back of your garage if you have space behind to extend in the future 😁
Really enjoy the series/project. Really good workmanship. Only thing on my mind is the stance doesn't look right...... is the offset right from the wheels?
Nice video
Cars that make many short trips and don’t spend enough time at operating temp can collect a lot of water in the oil
Klepspeling wordt kleiner bij slijtage! Kleppen slijpen in de zitting waardoor de speling kleiner wordt. Mvg Pieter
Where is this? I live in Belgium too!
Cold start idle seems a bit high to me?
Nice videob
I hate to be that person asking about something else, but any idea when you'll start your Golf 2l Weber build? I literally can't wait, I'm so excited for that
After the bmw is on the road :)
Carbon buildup can increase compression ratio too
Well seeing the poor state of the intermediate muffler, do you think it will pass Belgian technical inspection?
Otherwise it is great to see someone of my age working on same type of cars ;)
MORE VIDEOS OF THE BMW!!
my favorite part is when you did the thing
