valve stem seals 4.8is
I need advice on how easy it is to DIY the replacement of Valve Stem Seals on my X5 4.8is. The ODO meter reading is 110 000km and recon the Valve guides should be fine.
If I take the cams of and mark each position and mark the timing chains in relation the the sprockets, how will the Vanos setting be effected?
To take the car to the Dealer will kill me financially as their Quote is like changing the whole engine!
