Hi DonCherry,

老车开始烧机油： 车每次发动后3秒之内冒蓝烟，然后就没有了。换机油大约一月后每星期要添0.25L. 朋友说换valve guide seals。不知道是否值得？ 若不换，还能开多久？

DonCherry

Most things you can do is to try with high grade "stop smoke"
sealer and oil treatment, which you can find in Canadiantire.
Repairing the valve stem is a job, cost would be as same as
the value of the car.

Yes, it sounds like valve stem sealer problem.

多谢DonCherry。 祝好。
