[Shop-talk] I'm embarrassed to ask, but I need a little help.

OK, I really hate to admit that I'm stumped on this one.  But hopefully 
someone here will have an answer.

I have a 2007 Mercedes GL450. The VIN is 4JGDF71EX7A185071. I bought 3rd 
hand. So I don't have all the paperwork.
I am getting conflicting information on whether it is a 4.6L or 4.7L. My 
dealer is telling me it's 4.6*, but the VIN search I did is coming up 4.7. 

(*dealer is only telling me that after he looked on his system when I gave 
him the VIN on the phone. I was on hold for a long time, so I'm not 
confident.)

Is there a place I can look find this out for sure? (can some of you run 
it in any of your systems so I can get a consensus?)
No one on MBWorld answered my question.
The VIN decoder there (and in other places) gives me "We could not find 
any information for VIN 4JGDF71EX7A185071"

I need to replace the valve seals and the there are two different kits 
depending on what engine.
I took off the covers and found this Motor number -0077941. Can anyone 
tell me what engine it is from that? Thanks.

Thanks a ton.

BTW, does anyone have a recommendation for a place to buy the valve stem 
seals? I plan on doing a whole youtube on the replacement, so I want to 
make sure I have the right ones when I tear into the motor.
Thanks again. 

BTW2- who offers a 4.6L AND a 4.7L engine in the same year and model?
