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)?

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.
