Last yr I bought a second 89 Hurricane with a blown motor. Took it out, got a motor for a shop up by me last yr with 7100 miles. Finally got all put together, finally got it started, and antifreeze starts spewing out of my crank case. I'm so pissed, cuz that means the shop sold my a crap motor, and they won't do anything about it.

 

Now I got to take the motor back and out change the head gasket.

 

they give you any kind of 12/12/ warranty or anything?

 

Nope, no warranty. At least thats what they are saying. I'm gonna look for my receipt and paperwork. I know I kept it, just don't remember where I put it.

 

Before I get way ahead of myself, I just thought of something. When I cleaned the carbs, I put them back together, but I didn't have the fuel/air mixture screws right, so I had to keep adjusting them to get it running. While trying to start it, it kept backfire. With the bikes high compression, would it backfiring cause the heads to crack?

 

backfiring shouldn't cause the head to crack. it was probably bad from the place you bought it from. can you tell exactly where the coolant is coming out? there are two metal pipes that connect the head to the radiator, my bike was leakin from one of the tubes, a simple o-ring fixed it. if its comming out from imbetween the head and cylinder block, you might try retorquing the head. i think you have to take alot of the stuff off to get to the head bolts, so it might be just as easy to go ahead and replace the head gasket.

 

If it is leaking from the pipe, and I need to replace an o-ring, would it be leaking down into the crank case?

 

no, if its from the metal pipes, it would be an external leak.
i re-read and saw its spweing from teh crankcase, probably gonna have to pull the head.
hope its just the gasket, plan for a cracked head...

 

A couple of questions:
Where exactly is it "spewing from the crankcase"? Various plugs and O rings etc (some external, some internal) would leak coolant if not tight. Even better, how about some photos?
Did the shop do all the assembly of the engine?
