Thread: Knocking in Timing Cover

Tweet

There is a knocing in the timing chain cover of my 2 yea old 427 bbc. We figured out that the cam was walking out and the cam button is hitting the cover. Where do I go from here to stop this noise? Any suggestion??

do you have a gear drive on it?there shouldn't be but like a 1/16 of an inch clearance between the button and cover.the big gear(on idler drive) should be on the pass. side of engine.it provides a "mesh"and causes the cam gear to want to push cam into engine.if the big gear is on drivers side it could cause it to want to "walk" the cam out.just a thought

Remove the waterpump, drill a hole in the timin' cover, then weld a nut over it, make sure it lines up with the cam gear center, then just install a bolt in the welded on nut and tighten it 'til the noise stops... Re-install the waterpump!!

I believe a much simpler solution wood' B earplugs.

Or ............................. from my house buildin', door shimmim' dayz. A wood wedge (shim) betwixt the pump N' timing cover. Drive it in while the engine iz' runnin' soz' ya' don't get it too tight. Nuttin' worser than givin' yer Big Block a wedgie.

Replace your timing chain

YEP, and while ya got the cover off, don't ferget to drill that hole in it and weld the nut on too..

And keep some shims handy..........

or just answer the door.

In continuation of the "music depreciation hour", maybe you shouldnt answer the door. After all, Who Let The Dogs Out?

I didn't know the dog would get out if I opened the door ....... HONEST. It won't happen agian.
