Have a 91 Cutlass Calais. Am losing a gallon of coolant every 3 days. No visible leak with pressure test. Am getting milky substance on top portion of dipstick, but not on lower portion. Oil level is not rising. Do I have a blown gasket (head/intake)?

Do you
have the same problem?

Adding to the above question, there is NO smoke coming from tailpipe and the oil at the bottom of the dipstick looks normal.

If you are getting a creamy substance mixing with the oil, there is a good chance you have a head gasket leak. Check engine compression to see if there is a weak cylinder.
