I have a 2003 Chevy Impala, not sure engine size, approx. 52,000 miles. Bought car approx. 4 months, ago, with 48,000 miles. When checking oil, noticed using oil at a rate of 1/2 to 3/4 quart per month (approx. 1000 miles per month). Also noticed coolant changing color from orange to dark brown or black in color. I have not noticed any coolant in oil. Does this mean a blown head gasket or crack in block ? Car has a six month, 6000 mile powertrain warranty from dealer. I assume this would be covered under such warranty ? Any suggestions on how to procede ? Is car worth fixing ?

sure sounds like some of the indicators of a head gaskt, manifold issue, etc* - You want to get this checked and documented ASAP. Hopefully this was a AUTHORIZED or licensed vehicle dealer. *different engine may have different issues BUT a serious indicator for all engines.

They are telling me there is a blown intake manifold gasket. Would that account for the oil in coolant and excess oil consumption? What little I know makes sense to me, I didn't notice any coolant in oil, which would be a blown head gasket? Thanks for your help.

On certain engines the intake gasket can give those symptoms. I think the 3.1 is one of them. The 3.8 had a problem with the manifold itself. Taking it apart is the only way to find out. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.
