Looking for some advice. We recently removed the exhaust
riser on our engine
and discovered these crystals in the exhaust
outlet on the block.
There is only one thing I can think of that it might be. Last summer our exhaust high-rise snapped due to a faulty weld and with no pressure to push it out some cooling water
backed up into this area. I thought we would have noticed this at that time if it was there then, but maybe we overlooked it? Any other ideas what could cause this?
runs fine, no smoke or anything. Any input appreciated.
