Re: Mercruiser 3.0 Intake Manifold Question
Ayuh,... Welcome Aboard,... Got a picture,..?? you might be right...
UPDATE: Tried to crank engine and guess what... hydro-locked. Ughhhh, 1/2 gallon antifreeze went into intake manifold.
I removed the spark plugs and cranked away. Got all of the antifreeze out, I think. Cleaned spark plugs and started engine. It runs! :redface:Ran for 20 minutes then fogged engine and cylinders. Checked oil on dipstick. No indication that antifreeze got past rings into pan.
Lesson learned: After removing block and intake manifold water drains, ONLY introduce antifreeze via ear muffs at out-drive!!!
It looks like I escaped a $5,000 mistake. Lesson well learned.
