the problem possibly is that the crankshaft you used may be a longer stroke that the one you removed ( you state that you change the crankshaft of the m43 with another crankshaft) Assuming that the engine is not a diesel engine problems that you will have besides the extra height, is an over the top compression pressure which will require top octane fuel or special fuel one way to lower the compression pressure is to fit pistons with a hollow in the crown ( low compression pistons) go to a speed shop and you may be able to get an over thick head gasket to stop the piston from hitting the head and to lower the compression pressure as well look around and talk with speed shops and engine reconditioning engineering shops as there are different sized pistons that have the gudgeon pin set closer to the crown which will make the crown flush with the block I think that you will have to research the bore and stroke of your engine and the engine that the crank came out of to see if there is a difference and work on that angle if such a difference exists of course if it is a diesel, it is probably right it you use the correct head gasket as diesel engines have very little clearance between the head and the piston crown

what do you want to know

check brake and gear box fluid

bmw have twin turbo when move from first to second could be possible check engine and gear box oil

starter not working

low water low on coolant

low water

change plugs and air filter and fuel filter also change coil ht leads

check mass air flow sensor

Lights on these cars all run through an LKM box = light control module. It's purpose is to turn on a warning on the dash when some bulb is not working, and all models up to 1994 have terrible problems with failing headlamps, turn signals, brake lights, etc.due to poor solder joints in these modules. Very common for headlamps to fail driving down the road, or fail when changing from dim to bright. It is possible to repair by heating and re-soldering every connection in the box, but far easier to get one from a 1994 or later junk car, if you can find one.

My 1989 735i is.

Poor antenna connection? Bad ground fr antenna?

Check coolant temp sensor (not the sender for the dash indicator but the one that talks to the ECU). These fail often and will tell the ECU wrong temperature data such that the fuel mix can be way off. They usually do not cause check engine light to be on. This can be tested with ohm meter if you have a temp chart with readings. Easy fix.

You don't have radiator cap? If not, fill it through top radiator hose fitting. If no radiator cap, I guess you have a surge tank? You should be able to top it off in the surge tank. You will have to keep an eye on the coolant level. I don't know if your cooling system has air bleeder valves? If you don't get the engine and radiator full of coolant, the liability is yours. I can't see anything from here. I didn't see model year listed or I would look up your radiator info.

Well the warning light is probably on because the cam timing is not right. So yes it will probably stay on until you get it fixed.

I would guess it would cost you about 350 dollars to have that done.

Check rear shockabsorbers!

do you have fuel pressure at rail when the injector gets the ok to open
