Being as there've been so many posts about intake manifold gaskets in
here lately (great stuff) I figured it's time to ask this question...
Is it a head gasket or intake manifold gasket (or both?):
The woman has a 95 Olds Cutlass Supreme SL, 3100 motor, and it's
eating coolant like crazy, roughly 1/2gal a week or so (this is just
an estimate so please don't take it literally). It's definitely not
leaking it, no puddles, etc. There is no coolant in the engine oil
itself, she just had an oil change and there was no coolant in it. It
had dex-cool but we flushed and filled with universal coolant (amazing
universal coolant looks more green than anything, but that's besides
the point...) The overfill tank has the tell-tale brown "crud" in it,
as does the upper neck of the radiator. The old coolant looked like
it was so disgusting.
Anyway, looking for advice, procedures, "make sure you do this and
this and that" info, et al. Any and all help is appreciated, and if
you need any more info I'll provide what I can, thanks in advance.
