Gentil79 Posted September 15, 2022 Share Posted September 15, 2022 Hi everyone, Progress has been made on my South African 1974 BMW 520 E12. After more than 10 years of not being used, I attempt the first start. Of course, I had to do a few jobs beforehand. Here is the video I’ve made: First start in over 10 years - 1974 BMW 520 E12https://youtu.be/ms6BaA9Kctw cort1977, Asimo, JJ0063 and 14 others 17 Link to comment Share on other sites More sharing options...
sutty2006 Posted September 15, 2022 Share Posted September 15, 2022 Love it. I wanted to do the same with the Carlton. 14 years that hadn’t ran for. Engine wasn’t as seized as yours. It freed off pretty easily with some wd40 down the plug holes. Compression test came next, then the fuel hoses and filter. Drained the tank, then with some fresh fuel she ran. im too impatient to do these videos though. The wife said she’d help me with her decent camera and some basic editing skills but I’d already got it running by the time she’d found her camera.

Spiny Norman Posted September 15, 2022 Share Posted September 15, 2022 Excellent! Always love seeing an engine fire back into life after a long slumber, top work. Gentil79 1 Link to comment Share on other sites More sharing options...
Nullzwei Posted September 15, 2022 Share Posted September 15, 2022 That looks to be very unrusty for a 1970's BMW. Very rare. Mayo in filler cap is probably just condensation. Those 4 cylinder m10 engines are difficult to kill. Used in F1 in turbocharged form they made stupid horsepower. Gentil79 1 Link to comment Share on other sites More sharing options...

I use my old iPhone XR to record and edit and I’m happy with the results. Compression test is next once it find it, as well as an oil and filter change. sutty2006 1 Link to comment Share on other sites More sharing options...

Yes, it has spent 5 years in South Africa then 43 in Portugal. There’s a scab here and there, but not too bad. I need to douse it in Lanoguard before the winter kicks in! tough engines and not bad to work on either. Link to comment Share on other sites More sharing options...

Yes, bought new in SA in 74 and imported to Portugal in 79 where it remained until the Summer of this year. anonymous user, sutty2006, tooSavvy and 1 other 4 Link to comment Share on other sites More sharing options...

Gentil79 Posted September 25, 2022 Author Share Posted September 25, 2022 More work yesterday on the 1974 BMW 520 E12. Oil & filter change and looked at the spark plugs. They’re the wrong ones and gap was too wide. Went for another mini drive and idle still crap. New ignition parts to be ordered (dizzy cap, rotor arm, condenser and plugs) valve clearance to be adjusted and timing to be check. Only after all that is sorted the. I can start the carb tuning… which I still need to learn. djim and BlankFrank 2 Link to comment Share on other sites More sharing options...
