１月末の１０日間、私は、慶應病院に入院、耳下腺腫瘍の摘出手術をしました。直径５センチもの大きな腫瘍を左耳の下、首との間の顔面神経をかいくぐって、摘出。幸いにも良性腫瘍ということで、若干の左顔面神経に後遺症は残るものの、月末には退院することが出来ました。いわば「タケシさん顔」で、目下リハビリに励んでおります。ちょうど、この間、「・１２２」のエンジンは、田中工業（JUN MACHINE SHOP）にオーバーホールに出していました。そして、私が退院すると、ほぼ同時に、オーバーホールされたエンジンが、工場に帰ってきました。田中工業は、エンジンのオーバーホールとチューニングでは老舗です。シリンダーは、「MAHLE」の１ｍｍオーバーサイズピストンに合わせてピカピカに研磨され、メタル合わせもすべてバランス取りが行われました。シリンダーヘッド上面は０．２０ｍｍ、下面は０．１８ｍｍ、シリンダー面は０．０７ｍｍと、実に繊細に磨きこまれ、きちんと「シリンダー加工成績表」と「メタル合わせ成績表」が添付されて戻ってきました。これから、エンジン各部の組み付けを行い、Ｎさんからお借りしているスペアエンジンとの換装作業に入ります。「メタル合わせ成績表」によると、クリアランスが０．０７５〜０．０９ｍｍと、ちょっと広く、ばらつきがありますが、旧いエンジンですし、多少オイルの逃げはあると思いますが、エンジンオイルを少し硬めの鉱物性シングルグレード（４０番くらいか、、）を入れて、じっくり「慣らし」をやろうと思っています。私もリハビリで「慣らし」、「・１２２」のエンジンも、じっくりと「慣らし」、をして、春のクラシックカーシーズンを迎えようと思います。
For 10 days at the end of January, I was at the Keio Hospital to take out a parotid tumor burried below my left ear, neck and facial nerve. Fortunately, I have now found that it was benign and I was able to leave the hospital by the end of the month, albeit with some facial difficulties. One half of my face does not easymove and I am now doing rehabilitation excercises. During my hospitalization, my .122 engine was out for an overhaul ”Jun Machine Shop/Tanaka Kogyo” which is an old establishment well known for its skill for overhauling and engine tuning. The cylinders were polished to match the "Mahle "1mm oversized pistons and the sealing was professionally finished. The cylinderoverhead was 0.20mm above, 0.18mm below and the face 0.07mm. It came with a score card showing the results of the work and metal matching. According to this data, the clearance is a bit wide at 0.075-0.09mm and with some variance but this cannot be helped being an old engine. A bit of oil - perhaps a #40 mineral single grade oil - for breaking the engine in. Along with my health my .122 and I will be working our way back to full tuned health in anticipation for the upcoming Spring classic car season.
