4. Reported cause

   油を頻繁に交換してスラッジを洗浄するようアドバイスされたが、スラッジは堆積を続け、冷却水と油圧の喪失の謎は二回さらに底を尽き、インターネット上の記事で、自分の車を含む複数のGMC車は、時間経過に伴いひび割れが生じた欠陥シリンダーヘッドで製造されており、このひび割れにより冷却水がエンジン内に漏れてオイルと混合し、スラッジが堆積することを発見した。 Machine translation (unreviewed)

   I WAS ADVISED TO CHANGE THE OIL FREQUENTLY TO CLEAN THE SLUG OUT BUT IT CONTINUED TO BUILD UP AND THE MYSTERY OF LOOSING COOLANT OIL PRESSURE HAS BOTTOMED OUT TWO MORE TIMES AND I FOUND A ARTICLE ON THE INTERNET THAT A NUMBER OF GMC VEHICLES INCLUDING MINE WERE BUILT WITH DEFECTIVE CYLINDER HEADS DUE TO CRACKS OVER TIME WHICH ALLOWS COOLANT TO LEAK INTO ENGINE AND MIX WITH THE OIL WHICH BUILDS UP SLUG.
