  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

2012 Husky TE310 Mystery Oil Leak Hole in Head

Hello Fellow Husky Owners, Can any of you identify what this hole is in the head of my 2012 TE310? I appear to have oil coming out in the head area under the water pump. I tore off the water pump and took a photo of where I think the oil is coming out. It appears there is an "open" machined hole in the head that is under the water pump. The hole goes into the head cavity quite some distance... at least I can stick a cable tie 3-4" into this hole. I have also tried to blow into this hole to see if it is just a dead machined hole and it appears to go into the head where the oil would be contained (hence is would make sense that oil would also come out of this mystery hole). I have checked the parts diagrams, and the service manual and I am not finding anything related to this.

Can anyone tell me what this is and why it is not plugged or what to do to stop oil from coming out of this location? I Have a pencil pointing to the hole I am thinking oil is coming out of.
Any help or ideas would greatly be appreciated.

This is a new bike to me (bought it not running for a song) and so far, I do not yet have it running right. It was "seized", but when I tore it down, I found out the seizing was not in the head, the piston/cylinder or the crank. I was the infamous starter gears that everyone seems to have trouble with. This does mean I took it apart and reassembled it, but I don't remember doing anything related to this hole.

On the good side, I can now get it to start by bump starting it, but with this oil coming out, I don't dare run it long and it is not yet running right.

Also need a kickstart lever if anyone out there has one they want to sell or if you know of an aftermarket one that would work on this bike.

Thanks for any help anyone can give. Brett
 
Over the weekend with the help of a 310 community, I was made aware that this hole is a drain hole that is used to drain water and or oil out of the spark plug cavity in the head. The reason why mine was leaking out oil was their is a gasket/o-ring that goes around the spark plug hole to seal between the head and the valve cover. This gasket/o-ring shifted out of place when I put my valve cover on. Just wanted to report this in case anyone else has this problem in the future.Screen Shot 2023-07-23 at 10.30.29 AM.png
 
bingo! shifted gasket...very common and scary but way easy peasy to fix. dont use goop/RTV on the the grommet or gasket. if the gasket flops, use some thick grease to tack to the VC during install and go slow. yer good.
