    Galvanic protection of the engine aluminium parts for any BMW from 70/80/90

    Galvanic refers to the flow of electrons between dissimilar metals. It acts as a battery and oxidizes the least noble metal and can protect the most noble metal (cathode). Galvanic action does happen without trying to protect another metal but can be used for that purpose. Galvanic action...

    Matching number engines // does your car have it?

    I have a numbers matching engine, but the head is not. When I had a new upgraded head installed, I gave the shop my original head to transfer all the useable parts. I asked for the original head to be returned but they threw it in a pile of old heads. I was told they found my head, but when...

    Vapor Lock? How to Prevent?

    I have an electric fuel pump on my firewall that I use to fill the carburetors after leaving my Coupe sitting for a week or more. The few times I've had a problem with vapor lock on a very hot day, as soon as the engine starts misfiring, I turn on the electric pump, and the engine begins to run...

    2800CS front brake rotors

    I don't go to O'Reilly's to get my rotors turned. My brother is a professional mechanic and has a resurfacing machine. The drawback is he is in Kansas and I am in CA. Fortunately, I will be there in a few weeks for an event on a ghost track that I participate in every year. Cost to me is $0...

    2800CS front brake rotors

    I am looking to see if I can buy them directly from dynamic friction. I also checked my rotors closer, and it looks like I have enough material to resurface mine. My Coupe will be disabled for a while until I get this resolved.

    2800CS front brake rotors

    I considered going to the 3.0 CS rotors but i don't like the idea of breaking the calipers open to install the spacers. If may be my only option unless I can find some dynamic friction rotors that fit my 2800CS.

    2800CS front brake rotors

    Jim doesn't know where to get them either. We discussed it when I got brake pads from him. I have had some issues with Rock Auto in the past, but this is the first time I got the wrong part.

    2800CS front brake rotors

    I knew finding new brake rotors for my 2800CS would not be easy, but it ended up being more of a hassle than I anticipated. I found Rock Auto had 3 Raybestos rotors, but all other brands were sold out. I ordered 2 of the Raybestos rotors trusting them indicating they would fit my 2800CS and...

    2800 CS brake problem

    That diagram explains what happened to my brakes. I knew there were two lines going to each front caliper, but I am used to dual brake systems separating front and rear brakes. I had a suspicion the two caliper lines were for the two separate dual brake systems but thought that is not a good...

    2800 CS brake problem

    I am a chemist and understand how liquids can become a gas and compressible. I also understand brake fluid does not need water in it to boil, water just lowers the boiling point. I do not understand how a hot caliper can cause both brake circuits to boil. I read the description in my Blue...

    2800 CS brake problem

    jmackro was partially correct on my issue. Even though I did not have any leaks initially, I had a lot of brake fluid on the garage floor under the left caliper two days later. That helped me to remember when I installed the pads, I bought a rebuild kit and decided to just replace the outer...

    2800 CS brake problem

    Yes, that would have helped. I did touch both front wheels and they were pretty much the same temperature, and I would estimate both under 150F. I think that is hotter than normal for the driving I was doing, but not excessively hot. I did not check the rear drums because the issue was...

    2800 CS brake problem

    I do have rear drums, but I am sure the front brakes that were dragging. That is where the smoke was coming from. The smell seemed to be more concentrated i the front too.

    2800 CS brake problem

    I can't get my Coupe on my lift right now but thought I would describe what happened to see if anyone has a good idea what happened. I was driving from Huntington Beach to Costa Mesa on the 405 freeway. As I got close to Costa Mesa, I felt a little vibration like a wheel slightly out of...

    FS: Golde wind deflector reproduction

    My sunroof is an original dealer (Hoffman?) order and installed by American Sunroof Corp. It is electric operated. What are the chances your deflector would fit my sunroof? I understand the install cost about half as much as the car back then. This was due them having to cut the hole...
