Why does this 42 Year Old BMW NOT start? E24 635 CSI - Restoration Part 1

Welcome to my first ever KZbin Video!
This is the first episode of my red E24 Restoration Series. Our first goal is to get the engine running so we can bring this beautiful 635 CSI back on the road! After that we will restore this car as good as we can!

I have learned a lot thank you

[@Adam-wu7vt]

Great work, and your trouble shooting is well explained 👍

[@SundayMotorWorks]

Thank you very much!

Love it, I just got a 1987 E24 L6 2 weeks ago so I will come along with you on this project. Mine has been off the road since 2017

[@SundayMotorWorks]

Congratulations on your e24! I will guarantee you that you won't regret it :) Actually I am quite far on the project now, recorded everything but I need to find some time to cut the video material. That part is extremely time consuming. See you on the next one!

@@SundayMotorWorks great to hear! My senson broke off and Im picking away at it.

Hi again SMW , I ran the engine without the rocker cover ( AFM /LMM plugged in but not in airflow ) to find major oil leak from the camshaft oil spray bar banjo bolt being loose . I tightened it and reset the valve clearances at the valve stem side and double checked them . Ticking gone ..... Wunderbar Hugo

[@SundayMotorWorks]

Hello Hugo, I am really happy to hear that you found your issue. As I said in the video these Banjo bold can absolutely ruin you day. I would recommend the check them every Oil change / valve clearance adjustment! Have a great weekend!

[@hugomonteith9284]

Thanks for that info . I will run the engine with the feeler guage between the valve and rocker to see if get rid of the tick . It’s only one cylinder and the tick is half engine speed . Difficult to isolate with rocker cover on ! Could be piston noise ( slap ) ? Vielen Dank Aufwieder Horen Hugo

Excellent purchase and diagnostics . I have a big coupe 635csi Shadow line 1987 model here in Neu Seeland { NZ } that I have what sounds like a valve clearance problem ( ticking noise ) . The cylinder head has been rebuilt ( 330,000 km ) after Gasket failure , Engine runs sweet with no oil consumption but after a recheck of valve clearance and reset again a fraction tighter I still have this tick ( Just like a tappet ) that starts to appear as the engine temperature rises from cold . Have you any ideas that may assist with this problem . Auf Wiederhoren Hugo Monteith

Hello Hugo, It's really hard to give you a diagnoses without actually hearing the car. Overall what can be said is that these engines do tick. You can reduce the valve clearance tighter and the ticking will be less, BUT the risk of cam wear is significantly higher then. I would recommend to go with OE clearances. However this dies not explain your ticking voice. I have seen calves which had damaged contact surfaces. Maybe doe to the wrong cleances over a long time. The contact surface between valve and rocker arm was extremely uneven and bits have broken out. If you adjust the clearance on such a valve I can imagine that once the engine runs the clearance is out of spec after some time eventually. So maybe check your valve surfaces.

Coll warte auf neue Videos , habe das gleiche Projekt in der Garage Bj. 88 . ; bei mir lief er nach neuen Einspritzdüsen.

[@SundayMotorWorks]

Die Düsen werde ich auch noch zur Reinigung zu "Vierliter" einschicken. Das tut denen sicher gut, auch wenn der Motor jetzt ja schon läuft. Der worst case wäre jedoch, wenn ein Ventil nicht richtig arbeitet und ein Zylinder zu Mager läuft. Das kann schnell zum Motorschaden führen.
