Today I installed a dual roller timing chain set on my engine (edelbrock). The instructions said not to install the original oil slinger any more. What's the reason for this ?

IME, the oil slinger just keeps major oil from inundating the front cover seal....I've always left them on the engines I've built but, if the timing set folks say to leave it off, they must have their reasons...

I can't think of a good reason why it should be left off...maybe someone else can enlighten both of us...*G*

Some chain and gear companys recommend this because there may be possible interference between the slinger and the chain especially if it is a "True Roller" set due to the extra large chain links. What you can do is install the chain and slide the slinger on and see if it clears at all points. Also be sure to check to make sure the T/cover clears the slinger once it is installed in case the crank gear is a little thicker. I however have never had such an interference on any of the engines I've built, and I always use the slinger. I'm one of those guys that believes that the factory puts those things in there for a reason. Sorry for dragging on,I hope this helps you out. Scott

The oil slinger would not fit with my Cloyes double roller timing set. It hit the back of the timing cover. I left it off and I don't have any oil leaks.

When you get ready to bolt the timing cover on be sure and slide the damper on the crank enough to help you center the timing cover seal around the damper. There is enough play in the timing cover bolts that it is easy to get this misaligned and it then will leak because of oil pressure and spray.
