Head gasket or Warped Heads?
 

I was driving my car yesterday when the coolant level warning began flashing at me, I pulled over, let it cool then put more coolant in it- it has used/leaked a bit since I got it- it also uses a quart of oil every 500 miles. However 5 min down the road the Temp gauge was getting to hot level and I turned my car off immediately. Checked my coolant, there was none in there at all. Soo.. I had to get home so I put more coolant in, and started her up.. all the sudden I had white smoke coming from my tail pipe. My dad thinks its either the head gasket (which looks like its already been replaced once) OR my heads could be blown and I might need head work done. Any ideas, or tricks on how to get at the heads with out messing anything up to get them checked, or worse good prices on new heads?
Im beginning to think this car has it out for me... I also have all the sensor lights going off- Bad ABS Module according to reading posts...any body know where to get it reserviced? I thought there was a guy on ebay who did it for 70.00...
Any help on any of these issues with the 1999 S80 T 6 would be greatly appreciated

RE: Head gasket or Warped Heads?
 

I would say Atleast Blown Headgasket.
I would have the Head removed and checked for warpage while it is off.

There is a Kit you can buy to test to see if the Headgasket is blown.

For the ABS module do a search on here and you should find a couple of places where you can get it done.
One of our sponsors even do it for I think $70.00 with a 5 year Warranty.
