My 1998 Olds Silhouette with 3.4L Engine is shooting water out somewhere from the block/heads under the front heat shield. Are there freeze/expansion plugs located under there that may have blown or rotten out? My Haynes manuals says nothing about freeze plugs.

Note: There is no signs of antifreeze in the oil when I checked the dip stick.

I hate to be the bearer of bad news..

But what your describing sounds like a blown head gasket, maybe intake manifold but most likely head gasket. Might be only leaking out and not in.

Good luck with that.
