Intake Rivets C3

[Sheldon S.]

I recently ordered some of the rivets that hold the oil splash pan on the underside of the intake manifold for my 71 BB 454, cast iron manifold. When I started to remove the splash pan I noticed that the pins that I took out are more of a split rivet and the new ones I purchased GM#10229247 are not split but have fine splines on them. Are these correct to use for my application and any special installation instructions?
Thanks in advance

i would put a little red loctite on them . some

people drill and tap for machine screws but i any case use the loctite. if they drive in tight they should stay in place

If they require gental tapping with a hammer into the holes and are the correct length, they will work. Terry

I would never put rivets back in the holes. Nobody will ever see them, and I feel a lot better knowing that there are screws in there with red loctite on them!

Terry's right, if you took the old rivets out gently, the new rivets just have to be tapped in with a hammer.

I agree, if you want to make it bullet proof. Put some machine screws in there. Tap the holes and screw them in. But, I am comfortable with the way GM did it. Take care, Terry
