broke bolt off in head

[Troutkiller2006]

i broke the top port side thermostat housing bolt in the head of my merc 225 2stroke, damnit! when pulling the motor off my chapparal so i could use it on the dually im getting that bolt looked like a good spot to secure the lift.when loosening it it turned maybe 1/8 of a turn before it snapped.

im seriously considering letting it slide and running the motor as is. its a 97 3.0 liter and that thing been on there a long time. i think if i keep an eye on it worse case it might leak a little but i dont think it woud put the motor in any danger if it does. and if it does leak i can deal with it then.what do you guys think?

you might get away with liquid gasket.

I just went thru a bolt removal problem with 2 bolts that were structurally important.

I tried a set of spiral screw extractors with no luck. Ended up taking it to a machine shop.$180

Beware of ezzouts or what ever you call them. Once your break them off, your in deep dodo

thanks guys. never broke the seal on the thermostat housing. was just trying to take the bolt out to hook a chain to the motor. my gut tells me that it will be fine but i should keep an eye on it. my concern is am i putting my motor at risk? if it does leak will it really hurt anything, so long as i catch it quickly?

Depends on whether it leaks or LEAKS....

If the housing cracks and breaks you could be in bad shape FAST

If you can, post a pic. A picture is worth a thousand words as they say. From a picture, we can tell you if it looks like it's in a spot where it will leak, and if it does leak, will it leak on something important that it SHOULDN'T leak on.
