following up on my previous post about coolant loss, the grand am w/
3400 engine w/65k miles on it went to the dealer after i'd gone through a gallon of coolant in about a month and a half , with no visible external leakage.I'd noticed some emulsified crap in the front valve cover when I changed oil about 400 miles ago. The oil I'd drained was dirty , but not a bit milky.The Dealer did a compression test which indicated pressures of 181# - 192# , and didn't notice any of the plugs looking any different / cleaner than the others.They also did a pressure test on the cooling system , and said the pressure never dropped. On my own I took an oil sample and sent it to a lab and am awaiting results. The dealer insists that the emulsion is normal , and there isn't any coolant in the oil , but I'm not convinced. Pontiac said I should continue to drive the vehicle , and take it back to the dealer if / when the coolant runs low...which should be every week or two given prior history.So.....where does that leave me ? I've got this feeling that this engine is destined to premature failure.....Just exactly how is the coolant getting into my engine , and why won't the tests the dealer turn it up ???- posted
