If you do that, look at the oil that comes out of the pan when you drain it. Does it have any metal flakes? Have you checked the oil level recently? What does the oil look like? Does the engine still turn over? Does it do it fast or slow? Start there and report back.
Take an oil sample from the pan. Sounds like water in the oil. Head gasket is my bet.
Check the timing belt to make sure it is taught, not dry rotting, and all the marks are aligned properly.
If all is okay, and you do not have definitive documentation as to when it was last changed, do a 120K service too.
