HEAD Gasket repair gone wrong.
I have a 2011 Range Rover Sport HSE. It has 170,000 miles on it, I am pretty sure it has a blown head gasket and I don't have 6k handy so I tried a head gasket sealant.
Had just replaced the coolant sensor, thermostat and hoses, and everything was working fine. Before I used the Bars Head Seal Blown Head gasket repair. I followed the instructions, added the sealent to the overflow tank, let run to operation temp, let it cool the went to drive gently for 15 min.
After 7 or 8 min I got misfires on 2, 3, 6 and 8 and codes P0300 and P0128 then it overheated. So I stopped to let it cool then limped it back my garage 2 blocks away.
I've got the sealent in but was not able to run the vehicle for the prescribed time. After I got it back I let it cool again and took the malfunctioning thermostat out.
Do I dare try running it for the instructed time without it?
In addition when I started the vehicle after I took the thermostat out. A splash of water came out of both tail pipes. But the water was clear, no coolent .
It and smokes a little but its taking to reach operating temp. I don't wantbrobeun it long, but I dont want that sealant just sitting in there either.
