 Hey everyone, welcome back Look what the cat dragged in. This is a 1984 BMW 733 Something it's actually in pretty good condition. It's just dirty. It's been sitting outside for About two years Totally dead. I actually took the battery out of my Subaru This one would not even charge. It is not too bad Just needs a good cleanup. No rust well Minimal rust Original wheels. I'm pretty sure this battery has some juice in it Now the last time it drove was two years ago, then it did not want to start So it was just left Let's see what happens. That's exactly what it was doing two years ago. It's still doing it transmission Fluid leak probably this line here. I'm guessing or maybe the main seal This could also be the main seal in the front Look how rusty the rotor is fuel lines So something made it. It's not the fuel lines that are leaking. It's oil that just made it made it there Brake lines fuel lines a bit rusty here Check out these cracks old rubber rear differential small leak And the oil seal here both sides Also on the cover Same story with the rear rotors Yeah, everything's binding on the rust Yep Rusty ball joint Or whatever is in there. Where is this the sway bar link? Is this a 80s sway bar? No, it's a control arm lower rear control arm and I guess Control arm link no idea what to call this but it does sure look like a just some kind of a link between the subframe here or the cross member and the control arm The floor is not too bad. I mean it's It's almost perfect, I would say there are rust spots here and there but nothing serious all the six spark plugs This one gave me a workout but they look just Terrible awful Especially this one. I mean look at the carbon build-up and the the porcelain on top is missing Here half of it is missing on this one All of it. I Mean this is yeah, I don't know if I should laugh or cry See, I mean it should look well I was gonna say it should look more or less like this. Let's say like this one, but see how this one is Barely sticking out. Yeah, they've been there for a while So I think BMW the far Cylinder from the front of the car is number one two three four five six so Number six being the worst Then five Yeah, I would say then four and Then one through three. They're above the same and these are Bosch BMW R6 862 did the spark plugs. They're still Maybe a problem with fuel delivery, but I'm gonna try it anyways with the new spark plugs Yep, okay, I added fuel just for the hell of it Let's see what happens. It's actually not cranking very healthy you hear the little how do I explain this It's not you know even an even crank is But it's seen much faster obviously. I wonder if there is no compression in in one of the cylinders but that wouldn't cause it to not start so there's definitely a fuel problem I'm gonna raise it up and remove the fuel filter okay let's see what we got here looks like this guy here is the fuel filter and this guy here is the fuel pump all right two wires going into the pump upper says ground lower says ground with the key off let's see what happens with the key on key is on I didn't hear the pump at all ground also ground got no power to the pump just to be sure I'm gonna jump the fuel pump sounds like it's working okay I checked all the fuses the relays the fuses are good there is no list what relay does what not even it doesn't exist in the book so switch them around here and there is seven relays eight relays switched worse was switching them around no luck there I'm gonna try and power up the fuel pump from a different source different battery and try starting it so it's not starting with the pump being on all the time hmm we may be faced with two issues electrical to the pump and fuel delivery to the engine think I'm gonna remove the fuel line from the filter fuel filter and run them run the pump and see if any fuel comes out okay as you can see some fuel came out when I took the line out from the fuel filter there was pressure build up on the line the guy on the left and then when I go to short the fuel pump there goes from the fuel pump so I'm gonna put this back together and go back to two under the hood I got fuel going by shorting the fuel pump looks like you know what old fuel but it's not too bad it's not that bad I've seen much worse so fuel is going in into the fuel rail did I check for spark I think it's safe to say that we got no spark okay now testing straight from the coil need one weak spark got the coil out this is the positive side ignition is on got power it should be open okay so power I know we got power what I just didn't get power right switched wires using the number five I believe wire from cylinder number five all right decided to do a compression test still know not getting fuel right before the fuel line and not getting spark it's kind of suspicious that's two that we're having the two issues together no fuel no spark I do I do get power at the coil but no spark straight from the coil now if I had fuel if I had power to the fuel pump then I would dig into the crank shaft sensor and and test that but since it's not easy not a it's not a five minute job the crank sensor is actually wired into this plug this is this is the wire from the crank sensor and there's no plug in between this this guy here and the actual sensor yeah not have any schematics I don't know which pain is for the sensor but since I don't like the way this thing cranks I decided to do a compression test because if the engine is shut it doesn't matter what it is if it's the one of the valves you know the head needs to needs rebuilt or one of the piston rings or maybe any of the piston rings are bad then the issue with the fuel and the no spark which is probably a totally different issue separate issue then we're looking at a big bill over here so maybe it's just not worth getting into it that deep okay did a test started with cylinder 6 I got 149 okay so number 5 55 about 55 number 4 151 2 3 maybe I know it's hard to say there's numbers are only read 150 180 so whatever it's good another 150 that was number 3 number 2 150 number 1 155 yep as suspected now at this point I could go on and do a leak down test to determine if it's the an exhaust valve intake valve or piston rings but you got to take it apart anyways at this point with this kind of old engine I don't even know how many miles this thing has so it's got 114,000 you know it's it's what it says maybe more who knows so yeah I think I'm done with this I'm gonna put it back together and color a day see what the owner will say an ECU and a whole and a full engine rebuild that's gonna cost quite a bit the car in my opinion it's not worth doing it it's not that special it is a nice car you know if this was the turbo version I don't really know much about these these models but I'm pretty sure this is not something special that was made back then is it worth it it's only up to the customer alright guys thanks for watching on this unfortunate outcome I'll see you soon
