OK, so I really no nothing about Mercedes engines, but I do know how to
google. Are you sure there are really two different engines with
different valve seals? It looks like there is just one engine that
is 4663cc, and it's just a matter of whether you round up or down.
The subject is discussed on this forum:<br>

More info on the engine and its variations is here:<br>

Edmunds talks about the <h2>2007 Mercedes-Benz GL-Class SUV with the
</h2>4.7L V8 AWD 7-speed Automatic. then in further down it says
the all-new 4.6-liter gasoline engine will be the only one powering the
all-wheel-drive GL450 in the U.S. market. That article is

I can see why you would be confused. I have looked through all this
stuff and it's not very clear. <br><br>

BTW, does anyone have a recommendation for a place to buy the valve stem

make sure I have the right ones when I tear into the motor.<br>
Thanks again.</font> <br><br>
BTW2- who offers a 4.6L AND a 4.7L engine in the same year and model?
