Just recently my steering wheel has started howling or whining during slow turns. Used to only do it when hitting the left or right lock. Can anyone tell me what causes this and if I should be concerned? Thanks, Jeff.

Thanks Glenn. So 4valves have more power but 2valves are indestructible. I'm assuming most recent diesels (i.e. E7) are all 4valve. Right?

Could one of the great Mack experts on this site please explain which Mack motors came with 4v or had the 4v option. What's the difference? Is it like gas engines where the 4v is generally more efficient. I'm specifically interested in the E7's. I currently own a 94 E7 350 and am looking at a 93 E7 350 where the owner lists it as a "350 4valve". The 94 is electronic while the 93 I believe is mechanical (if that makes a difference). Any help is greatly appreciated!
