That's going to be a nightmare to remove /or get access to the HVAC unit. Then finding parts. This is one of the worst cars that BMW ever built. Less than 33K, got worn Camshaft's lobes You or anyone has a tick tick dieseling engine, well that's the great BMW's camshaft defective Where can you buy camshaft /or camshaft kit that's not going to break the piggy bank? Or do they make something to compensate the worn camshaft's lobe? Somehow this series was BMW's top of the line. It did NOT live up to "The Ultimate Driving Machine" more like a gas guzzler & engine failures Which jerk of an engineer that decided to have metric wheels, metric tires, rechargeable batteries, TPMS, cheap rubber hoses in running within the HVAC installed on this series? Thank you for posting on the video repairs. Hope you can post more videos on your repairs. We mostly see people just showing off the cars. This series under KBB resale is a joke. Have a 1986 ATG M7 [modified from a 1986 735i (E23) with 1986 M635CSI]: BMW serviced
You do realize that these m30 engines have non hydraulic valves which require valve lash adjustment. That doesn't mean worn lobes that means someone never bothered doing a 20 minute service to the car. Lazy ownership. Usually new adjuster eccentrics will help with the adjustment procedure if you're having problems. The only BMW camshaft of the era really known to wear is the m21 diesel camshaft, though that was only an engine offered in the 5 series in the US for 2 years. Gas guzzler? I wouldn't say so either, my 84 733i averages 20-21mpg and I have averaged 24.5 mpg with highway only driving. The ultimate driving machine, the was a brand slogan, you're taking the heaviest car and biggest car Bmw made at the time and saying its not the ultimate car. Sure its not buts its an engaging and enjoyable car to drive especially when you optioned it with a manual trans or had a turbo grey market car in the US here. Finding A/C [arts really isn't that hard, maybe a bit pricey but not too crazy. Mercedes also used vacuum pods just the same, parts can be interchanged. Really the main let down of the system was the Bosch wing cell compressor. Those are usually tired and worn after 40 years anyways. So a system refresh with a sanden compressor swap will get that system working really well. Just can't have someone working on it that doesn't know what they're doing though. Metric wheel sizes were just an option btw, the standard wheel was a 14", super easy to get tires for. And BMW wasn't the only company to use metric wheels, domestics like ford did that too. The only rechargeable battery besides the car's actual battery that I can think of is the flashlight in the glovebox, and the SI board. Both of which are none consequential really. If the battery go bad in the cluster its an easy fix generally. TPMS wasn't a thing then either, but that was federally mandated but the government actually for safety reasons. And honestly the rubber vacuum lines in an e23 a/c system I've never seen go bad ever. It's the diaphragm in the vacuum pods that go bad, that was a common way to operate more sophisticated mechanical systems across the automotive industry so I don't think Bmw can be blamed for using it. It is just that the 7 series was the only model to use an automatic system compared to the rest of the models. So much hate for the 7 series, they were great when they were new but as with any luxury car they require upkeep.
@@7erDave The car was once once owned my a millionaire. And no he has no time to work on cars when he was out defending for our freedom. The car always was serviced by BMW dealerships /or BMW master mechanics down to wiper blades replacement. His wife, an attorney or her staff, always took the car in 4 repairs. Most of the time the car is parked & rested for sure after 9/11. Limo takes her. BMW of these claimed junks are know to have worn camshaft's lobes. I am still correct that these cars are gas guzzler that required super unleaded & dream of hitting 18mpg in the city. Putting NiCad in back of the instrument panel, TRX & TPMS (he owns a* 959 too) were dumb. Even for now, BMW can't make a better car badges. After 9 Summers, the badge logo fallen out. You are correct these series are very laughable at best in the used markets. But the parts demanded a premium prices. He lost his wife and three children from 9/11 on The World Trade Center. He was a former Col of the SAS & used to runs companies. He happened to be my uncle. *$88K to replaces four TMPS.
amazing video! thank you so much.
