    Double roller timing chain rubs block

     



    Hi Everyone,
    I intalled a double roller timing chain on my 350, but the chain is rubbing the block by the center oil galley. Do I need to take out the grinder and start gringing down the oil galley boss? Is this a common problem?
    Thanks.

    Well, I took the grinder and made some clearance for the chain, problem solved. Put it all together and noticed there is NO slack in the chain at all, the chain feels really tight, in fact maybe too tight. Is this is normal? Im wondering if this is just the way double rollers are, or if there should be atleast a little bit of slack? Perhaps it will loosen up after being run for a while?

    0 slack is what you want. Yes, it will loosen up after you run it some.
