Great informative post. I am guessing you have personal experience using both products and they did not work??...
Like I said in the original post. I am not claiming this is a 100% proven way to solve leaky valve stem seals, only that it did work for me (for now). I have only 1k miles on the car after putting the above said products in. The X5 is a winter beater basically an awd that can get me to the Mtn for skiing. Valve guide replacement is a heavy cost and if this works in the meantime why not. I know a lot of people suffer with this issue and not sure if this have been tried by some as a last resort. It's a very inexpensive to test as each product is only about $10 a bottle.
I will update this thread as I put more miles on the car.
