So just lost my whole coolant system in a matter for 5 minutes and it’s all gathered under the plenum in the valley
It’s a boss 290
The leak is happening from the rear, Ive followed the heater pipes and there fine so I’m guessing it’s one the metal pipes running under the plenum?
What ya reckon
{DESCRIPTION}

I reckon its a distinct possibility. Sometimes the O-ring goes where the pipe goes into the block behind the water pump. Luckily the intake is really easy to get off and put back on then you'll get a really good look.
