New style breather tube!!
Hey Everyone. Recently had to pull the RH cylinder head off my 97 D90. It seems back in '99 when the head was pulled by Brithish Motor Car Dist. in San Francisco, something got left behind, in the head!!! Pictures attached. One day while I had the Seafoam out and was cleaning the back of the engine, I saw a breather tube laying flat on the bell housing, grabbed it to pull it up and noticed there was another that seemed to "disappear" into the block. I instantly realized where it was going. The po had complained on several ro's after the head pull of steam form the exhaust...go figure. Turns out it was the ZF extension breather and by my calculations, a full 10" of the breather tube including the hook portion was trapped in the head and burned by cylinders 5 and 7. It went 50k miles without a complete failure..amazing!!!
