DIY M52 M54 引擎的雙可變氣門升級油封（Twin Double Dual VANOS seals repair upgrade kit）

[djzeke]

我是看到國外網站下面這一段寫的，請ST大大你可以斟酌考慮換了吧，
所以我認為應該已經內漏了，拆下來沒內漏的話，來鹿港我請你吃道地小吃。

The following is an E46 & E39 double vanos piston seals R&R (remove and replace) procedure.

If the valve cover gaskets are over 40k miles (64k kilometers) old, then it’s prudent to replace them during this repair. If they are over 80k miles (128k kilometers) old, then it is a requirement to replace them during this repair, otherwise they might leak due to being dismounted and reused. These gaskets have an estimated lifespan of ~60k miles (96k kilometers) and replacing them during this repair requires no extra effort. The needed parts and replacement procedure are included as optional.

之前蛋王大大也剛剛分享DIY更換可變汽門油封，二位大大的心得分享真令人佩服。

小弟的車目前里程數都還不到，E46 330i才剛剛10萬，E60 530i也才四萬，如果哪一天也出現同樣症頭的話就可以效法二位大大了。
