I have a 2006 nissan murano and I changed my plugs yesterday. The intake plenum has to be removed to get to the plugs. So I started it up this morning and it was running very rough and white smoke was flowing heavily from the tail pipes. I pulled everything back apart, the plugs were soaked and I found a vaccum line I had left off. When I removed the intake plemum coolant ran out of the air intake. Now I have replaced the wet plugs, plenum gasket an reinstalled everything correctly is there any danger of hydrolock ? I plan on changing the oil in the morning and bringing the coolant level back up but what else can I do to prevent futher damage ?
