BHG symptoms...but no BHG?

I too had the same problems, blowing coolant out reservoir, no hot temp on gauge, negative test for exhaust gas – but in the end, it still was a BHG, The best test for BHG in No 6 cylinder is to look at spark plug – you will see a difference in the plug for the BHG cylinder compared to the rest (looks like the coolant color). The EG test does not find minor leaks when the compression is high.

Looks at the plugs and if it looks like a BHG, Runs like a BHG and smells like a BHG – then it probably is!

I had to pull and rebuild my engine as a result.
