1981 Honda Goldwing Possible crack in water jacket?

Post by Clay3Weil »



I have recently bought a 1981 Honda golding 1100 for a pretty good deal and the guy didn't mention anything about it having not one but both heads cracked, will not hold any water/coolant. so I bought new heads and had them installed but I'm still worried the water jacket may have a crack in it which would lead to having water or coolant drip into the oil. if this is the case is there anyway to fix that issue (the crack) or is that motor pretty well shot. Thanks for the help

If it had an external leak in the water jacket it probably could be fixed but internal I doubt it. Not very likely though. A cracked head is a rare thing too, must have gotten really hot. I would be concerned it got too hot and collapsed the rings.

I was thinking the same thing, I tried to get it to even turn over yesterday and I'm running into another problem that I'm at a dead end with. the battery has gods plenty of charge so that's not the issue but when I try and turn it over the starter makes a vibration sound but seems like it wont move so I was thinking the starter was out but I took it off and hooked it up to another battery by itself just for a second and it spins fine so I put it back in and still had the same problem? any suggestions or ideas?

I’d remove belt covers and see if they’re intact, then remove spark plugs, turn kill switch so there’s no spark, place rags over the spark plug holes, and see if it turns over. I would use a socket and go easy first and have a fire extinguisher handy. You could have a simple hydrolock in one cylinder or more. Check your belt timing marks.

If it is, and it’s coolant, you have issues. If it’s fuel, you have issues, but should be able to get it to run still, just remember to turn the fuel off every time you turn the bike off. If much went into your oil, that will need to be changed.

Since you did the head gaskets, failure to get the small oil orifice in its proper orientation could result in coolant leaks and allow coolant into the oil.

timing belt is in good shape, I'm sure when I took the heads off I didn't get the timing lined up perfectly like it should but that still shouldn't stop if from atleast turning over I don't believe? and I should use a socket for what? removing the plugs obviously?

You can’t be off by more than a few teeth without piston-valve interference. There is only one right tooth to put them on when timing. You better revisit that.
Get the T1mark lined up. Check your marks. Adjust them until they are correct. Some bikes won’t line up exactly on the marks, but less than 1/2 tooth difference. This is probably due to the marks on the back plates and how they are tightened. There is a little slop in the holes.

Use a socket or wrench to see if the motor turns over rather than the starter at first. If it stops turning, don’t force it.

Do you recall the orifice I referred to? The small end goes into the block, the large end goes towards the head. It’s a bit counterintuitive. The large end fits the block nicely, but it won’t let the head torque down that way.

Did you check for Hydrolocked? Pull the sparkplugs out and see if it will turn over.

I pulled the heads back off again lastnight and checked out the cyclinders they look fine and pistons are in good shape too. I took a hammer with a rubber end on it and put the rubber end on the piston just to give me a little leverage to push, they moved slowly and surely and by the time I was done cleaning them up and pushing on them they all move real well now and you can hear the chain in the crank case moving so I took to cover plug to the crank case out and tried turning it over by hand and couldn't get it to turn at all, any ideas?

Makes no sense. If it turns by pushing the pistons it should turn by the rotor bolt. Did you try the starter with the heads off?
