    rough running

    The fact that you report the engine runs well when cold suggests (to me) that the problem does not lie with the integrity of your points. However, the screws fastening the points show "use," prompting the question, what gap setting are you employing and have you possibly measured dwell? (This...

    rough running

    Food for thought? Although your ignition points setting can affect your ignition timing, I doubt your problem lies there. You describe the symptoms as only occurring when the engine has reached normal operating temperature. In other words, when the engine is kalt, it runs "acceptably."...

    M5 Guibo fail

    Without additional images of the giubo, I would not be so quick to condemn it as "going bad." (I have yet to see a giubo "going good") Per Andrew's observation, rag joints are the so-called weak link in the drive train and designed to absorb repeated shock, loads and naturally-occurring...

    WTB-gauge cluster

    Bear in mind that while the E3 gauge set may fit, not all speedometers/odometers will read the same - unless your rear axle ratio matches the replacement gauge. 3.64/1 is typical, but not necessarily. https://e9coupe.com/forum/threads/what-differential-gear-ratio-to-what-speedo.8252/ Also...

    Brake pads: Textar, Jurid or ATE?

    Over the eons, I have experience with Pagid, Mintex, Textar, Jurid, Ferrodo, REPCO/PBR and PBR/Axxis "branded" pads on numerous German cars, including E9, E3, and type 114. My preference leans toward what used to be labeled Repco Metal Master pads. They have been around from the '80s and...

    Suddenly blue smoke while idling

    I did not consider the photos due to a small viewing screen. However, upon closer inspection, even without the newer images, it would seem that the cylinder walls were merely "rehoned" rather that bored and honed. If there was any reboring, it may have only been to remove the upper cylinder...

    Suddenly blue smoke while idling

    I am not fully certain that I understand your concerns or the magnitude of those concerns. First, as to the engine oil leak from the front of the engine, your photographs suggest leakage from a stud or above the stud. This suggests the leak is from the cylinder head gasket or (far more...

    Hand signals

    I've been guilty of focusing on inattentive drivers behind mine - and have had passengers who have chided me for doing so. Once I pulled far ahead of an inattentive driver but managed to get stuck at a long red light. Watching the rear view mirror, it was obvious (to me) that the other driver...

    Period radio (1972) info?

    It may sound like sacrilege, but there were other choices besides Becker and Blaupunkt available in the early '70s. To be sure, the two Bs were probably the most popular of the higher end radios, but Philips and Grundig also come to mind. There were likely various dealer incentives to sell and...

    First time started after 4 months

    Do not resort to hacksaw or prybar. This image is similar to E9 knob. Note hole at 6 o'clock position. Take "L" shaped allen wrench or similar probe and push from backside through hole forcing cover from perch.

    Pulling brakes

    Easily overlooked is the road surface and, in particular, what is often termed "road crown pull." This, of course, should be obvious with or without any braking application, but a minor drift can be magnified by braking. While improbable, if you have glazed brake pads or rotors, or even...

    CSi engine dies after start up —> injectors

    Glad you have some answers to your quandary, even though they may be bittersweet. We tend to take a lot of things for granted, including the fact that possibly 45+ year old fuel injectors might not live forever. This is especially true if any fuel that might act as a preservative, is allowed...

    CSi engine dies after start up —> injectors

    Unfortunately, much of what is described in English can be lost in translation from the original German. The simplest question to answer is trigger point maintenance. There is no obvious adjustment for this unit and thus no ordinary maintenance is recommended. The trigger points were...

    SOLVED: L-jet Runner Differences

    Your initial post left me to assume that your were concerned about "basic" interchangeability between the pictured manifold runners, and whether the differences were merely cosmetic. (Curiously, the parts book describes these runners as "suction pipes" and "intake tubes.") FWIW, typical E9...

    SOLVED: L-jet Runner Differences

    As best I can recall, the runners are basically the same. Extra material can be carefully removed with grinder. https://www.e9coupe.com/forum/threads/anybody-else-do-the-e21-intake-runner-conversion.4258/ One of these vehicles may employ e-21 intake runners. (But maybe not.)o_O

    Are E9 brake master cylinders interchangeable?

    I am unfamiliar with RHD master cylinder applications. However, in a general sense, the bore diameter differences you describe would not significantly impede interchangeability. In theory, all things being equal, smaller bore diameter would affect pedal effort so that increased pedal travel...

    Brake Booster Delete or Downsize

    https://www.e9coupe.com/forum/threads/brake-booster-delete.15489/ Have heard that the FI Volvo P1800 used the same tii booster, or that they they can be made to interchange. That said, I recall seeing the same model Volvo with a slightly smaller aftermarket booster, that may have had a Bosch...

    Non Run issue....any ideas....Scratching my head.

    If the spark plugs are "sparking," how did you determine this? Did you actually remove the plugs, and if so, were they wet, dry, fouled, etc.? Unless you recently submerged your car, I would place the ecu last on the culprit list. Having pressure at the fuel rail is good, but the pressure...
