Depending on the what kind of a stop leak was used, it could seal up even a cracked head or block for a while. Since its not leaking now, it will be hard to find the problem until it comes back again.

Liquid crack filler added to coolant later & stopped up the coolant leak into combustion chamber.

Get the oil anaylized & check the sparkplugs, replace plugs that look suspect with new. Drive the car if you aren't doing further harm, accept that you need to have the heads rebuilt sometime, but with that mileage just drive it until you have to do any major repairs. Don't turn the radio up too loud.

Pro,
Good stuff...
Yes, I have read that several times before, regarding head gaskets NOT being the problem. I'm half convinced that his trusted Porsche mechanic of 10+ years took him across -- possibly even bought the car himself and fixed it to sell at profit. MAYBE NOT -- the PO was not a mechanic, and the car was 10+ years old with 158K miles, so might have been time to get a new car, to my benefit.

WHERE DOES ONE GET OIL ANALYZED??

Thanks.
