I have a 94 Ford Ranger it just hit 100k. It is leaking coolant so I believe that it is either a blown head gasket or blown intake gasket. I have talked to people about what it could be. One said its common for these to blow head gaskets while a couple other people said it is the intake gasket. Any help would be great.

 

It is often stated, "Test don't guess" ! Might I suggest that you have the cooling system pressure tested and maybe be a little more sure of the location of the leak.
Are you getting any white smoke on start up after being shut down a while?
Sometimes you can confirm things by removing the spark plugs and looking for unusual deposits on a plug that could be caused by coolant getting into that cylinder.
Ya gotta play detective sometimes ! Let us know what you find. Thanks
