greg Posted March 1, 2006 Share Posted March 1, 2006 I know this is going to sound like a stupid question to all you veteran mack owners but I'm just a newbie on owning one. I have a 300 e-6 , how do you tell if it's a 2 or 4 valve. Don't pick on me too bad. Lol. Aww go ahead I've got broad shoulders , I can take it. Lol.

You will find we are all quite friendly so you dont have to worry bout being a total n00b Go to this topic I started a while back. You might find the info you need there.As a quick note, someone said all the 4 valve heads had front mounted after coolers, the 2 valve had the side mounted after cooler. Might be wrong but read up anyways. Quote -Thad What America needs is less bull and more Bulldog!

HK Trucking Posted March 1, 2006 Share Posted March 1, 2006 Look at the valve covers. If they are the sort of flat looking aluminum ones, then its a 4 valve. If the valve covers are the rounded looking stamped steel kind with 3 hold down bolts on top, then its a 2 valve engine. theres lots of other differences too but thats the easiest way to tell.
