freeze plugs
I'm working on a friend of a friend's boat , who self winterized last year .
well he didn't do so well and blew out the 2 front plugs on a volvo 350. Ive got the engine supported and removed the mount on one side, so my question is do I just tap in the new plug after cleaning the rust , or do you use a sealer of some sort.

Also make sure you use brass plugs. Hopefully noting cracked.

Just about every kind of sealer has been used and successful just make sure you clean the core extremely well. Wire wheel and emery cloth or both. No visible rust or pitting before install. I've used permatex super 300, Indian head, and regular rtv sealant. Some use nothing however I'm not one of them.
He he got lucky cause blocks with popped plugs can and likely still crack elsewhere.

if you have a high oil level possible already crack. I would drain motor oil if all possible from the oil pan. Water ends up in the bottom of the oil pan as it will fall out from the motor oil over time

My .02$ worth, long and short. "Before" I bought my boat the STB motor froze at some point; I was making water the first 3 times out this year and couldnt find the leak. Luckly I ended up pulling the motor to do a coupler repair and discovered the cracks on the outboard side of the block in very close proximity of the large 1-5/8 freeze plug. When I removed the plug it was a colossal *****; once out I could smell and see the unmistakeable remnents of Loctite Red.. I'd say whatever you use, dont use that lol...
