Combustion gas in the coolant? I assume the green is the contaminated and blue is what it should be if no CO2 present?

200k is fairly decent for that engine or indeed most engines , few get much further these days

It sounded very rough in your little video so I didn't think it would end well.

You know I got a snicking suspension the engine was patched up when I bought it.
I've had that car maybe 8 years!
It had 199k on the clock. Cost me about 900 bucks.

Just as a chaser oil 10w30 Walmart brand.
Left the oil filter cap off.
Now I'm rewarded with cleaning up!
