Found this gem on the 07' Honda 8Hp today.

 

Im guessing its due to over tightening of head bolts but i could be wrong, and not having any service history have no idea when it occurred. 

 

Cost of repair is likely more than the value of the engine - which is a shame as it has had very little use.

 

Have yet to get a quote, but expect it will be dare, so no doubt a new winter project for myself if i can source a new block. Will have to manage with the trusty Tohatsu 3.5 for now. 

 

 

 

Has anyone seen this before?

 

 

 

 

 

 

We have snow on the hill too . . . . .

Is it possible that there was water in the water jacket, and it has frozen??????

Hmmm I wonder if the last photo might have anything to do with it...was it running well (not overheating) last time you used it ? If so and then its been frozen  its possible that the water jacket may of been full still and ruptured the casting as it froze . a bit of a long shot but weird stuff happens sometimes. welding it is a possibility if another block is expensive.

Yeah i did think about frost wedging, but i don't think it would get that cold in the shed. But maybe. Crack looks quite old, so i would say it was there before i brought it. Gutted i missed it when i brought it.

 

Will have a decent look this weekend if i get a chance.

 

Welding may be a good option.

Pretty hard to weld cast alloy, I'd say it's suitable for parts only.

Depending on many things including the shape, sectional variation, total mass and how contaminated it is it can be a piece of cake or super tricky welding castings... There are quite a few crusty old welders around that would give the little honda a good shot i reckon.New Plymouth should have a good quota of them
