The first sign of trouble was the overflow bottle filling up over each drive.
Then a watery noise through the heater core heard from the cabin.
Finally, the last straw was the car overheating driving on the Hume highway at 120kph at night time!
For a few weeks, I didn't want to believe it was the head gasket.
I checked every other thing and was convinced for a while that I just hadn't bled up the cooling system properly.
There was no emulsion in the water and I didn't seem to be losing any power or anything.
After enough time, and enough exposure to www.supraforums.com.au, I came to admit my mistake and park the car ready for a head gasket change.
Firstly I did a leak down test. Connected an air compressor to a connector that screws into the spark plug hole. Cylinders 1 - 5 seemed fine. But when we connected it to cylinder 6, the overflow bottle went crazy!
Sure enough.
Cylinder 6 was leaking exhaust gas into the coolant gallery immediately next to it.
If only I had checked the head bolts torque as soon as I got the car, this may not have happened for a decent while longer!
So off came it's head! Off the head went to the shop to get skimmed and ready for a Cometic Metal head gasket and ARP head bolts.
Several hundred dollars later and a bit of time taken to learn about how an engine is taken apart and put back together, and it was ready to rock!
A month later I was back at square one...
