My valve stem seals are reversed
I took a closer look at the cylinderhead after my wife picked it up and found that the black seals were put on the exhaust side and the yellow ones on the intake. I told the machine shop not to mix them and gave him the MB manual in case he need to look up anything and still did it wrong!!!!!!! It's going back first thing in the morning and must have it back the same day. He had it for two weeks. I guess I'll have to be late for work!
