My daughters 07hondacivic is losing coolant somewhere, thinking it may b thru headgasket. and when my husband changed the oil in it, it was sludgsy, don’t know if she hadn’t changed it for awhile(will never admit if she hadn’t), or is there some else wrong with it hoping not a blown motor, she just keeps adding antifreeze every week when it runs low
Well at least she’s doing THAT. Very likely a bad head gasket. If it isn’t confirmed and fixed very soon it can completely destroy the engine - water doesn’t compress!
