#1 of 2 Oil Leak?
Jan 22, 2012 (5:14 pm)
I've been told I have an oil leak in my left head gasket. I was told that it may or may not be serious-more serious if it leaked into my cooling system.
I really can't see the leak. I have ~134K miles on it and we were thinking
of getting a new car. They said they would monitor it and tell me if I needed to get a new head gasket. The entire service and parts would be around $2K so this is really serious for us. I was told by my local gas station that I should get a compression test for both my oil and cooling systems. Is this a good idea? How much would that cost? And what are the results that might come back and how should I interpret all that?
thanks for any advice, comments

You want tests that tell if there is oil in the coolant, or coolant in the oil, or if the cooling system will not hold pressure which means coolant could be leaking into the oil.
And most of all, you must monitor the coolant level in the reservoir, notice whether it keeps falling, and keep it topped up.
Head gasket leaks usually cause slow loss of coolant. If the coolant should become too low, like no coolant in the reservoir, the engine could soon overheat. The temp gauge would rise to the red, and then vapor might be noticed from the engine.
If this was not noticed immediately and the engine turned off, the heads could be warped, adding to the cost of the head gasket replacement.
