  • 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 The previous version was outdated and no longer supported.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!

Why am I leaking oil here?

I figured out how to get seal out. Back of Pump impeller was rubbing against housing. Flat surface of housing is pretty rough. I remember draining Rads and it was a greyish color. This explains why. Bearing has some play to it. I took some 400 sandpaper and cleaned up housing. Now I'm hoping Halls Husky has the parts I need. Hopefully this was the cause of oil leak. If not, waterpump needed overhauled anyway. Before and after pics.

Out racing, haha. The other side to that wife issue is having one that races herself and then you don't get to ride because you're the pit crew. After two years, my gf hops back on her bike and takes 3rd place, simply amazing.

Anyway, it looks like you got things sorted. Take that pump shaft out so you can lay that surface completely flat on a sheet of sand paper. You will be able to get a better even surface that way. You might also want to look into a spare stick coil since you got it really hot.
 
What is a stick coil? Halls had all the parts I needed to rebuild water pump!! Mechanic at Halls said oil leak is caused by a bad seal where spark plug goes. Ray Ray was right but I'm glad I tore apart water pump.

What's the turnaround time on going thru my motor and doing suggested mods? Any idea on cost? PM me with details. Hopefully motor survives Sunday's 2 hour race. Plan on removing motor Monday to ship out.
 
The hole the oil is coming out of is called a tell tail hole. It was correctly described as a no mans land between your water pump and engine side. It is on almost all bikes, so you can tell if the water pump is leaking (coolant), or the engine side (oil). Being that it was oil that was leaking I would bet it is the seal around the shaft that is the culprit.

My '13 TXC310R has less than 5 hours on it and is leaking oil from this hole! Above, someone said it could be the seal around the spark plug tube. Or is it a seal around the water pump shaft? I'd like to fix this. Anyone care to clarify? Thanks!
 
If it is coming from the tell tail hole, my money would be on the oil seal on the engine side of the shaft.

Well I guess it's not a 'tell tail' hole. The hole in question leaking oil (see pic), as previously indicated by couple others, leads directly to the spark plug tube. If oil is leaking out of this hole then oil is getting passed a seal and getting in the spark plug tube. I removed the valve cover and used some quality gasket sealant on the seal that sits in the top center of the valve cover and seals against the top of the spark plug tube. I'm hoping that's the only seal for the tube (I have not yet tested to see if the problem is fixed). It didn't appear that the spark plug tube was removable, so I'm hoping there isn't another seal at the bottom that could be letting oil in. I will find out if my issue is resolved and report back.

pull the valve cover off and remove the spark plug aluminum tube. There is an o-ring under there that will leak like that if its torn or worse, missing :eek:

That looks like a weep hole. I'd suspect the rubber gasket around the spark plug.

it is easy to dislodge it if you force a plug socket in there.

Have you recently changed your plug?
 
From the service manual there is also a rubber gasket at the base of that tube when removed.

That could be bad news for me. It didn't appear the 'tube' was removable from the top (with only the valve cover off). What page in the Service Manual?

Thx!
 
Ah, the 'Spark Plug Recess.' Well, I suppose no biggie if I have to pull the cover once again and redo it. Thank you for the pic and info.!
 
Sure enough, after sealing the top of the Spark Plug Recess (against the cam cover) and putting everything back together, it still leaked. So I took the tank off again and pulled the cam cover off and thanks to Johnrg's service manual post it was now obvious that the Spark Plug Recess easily pulled out. It's sealed with an O-ring towards the bottom. Service Manual says to grease before sliding the recess down and in. My O-ring was pinched and cut from the factory; I had never removed the recess before or removed the spark plug or did anything that could have caused the damage.

It was now obvious why I keep leaking oil out of the spark plug recess drain. So instead of waiting over a week for my local dealer to get the o-ring (want to ride Weds this week), I put the cut o-ring back in and filled the void with gasket sealer and smeared some extra around there and slid the recess back down and in. If it doesn't seal, I'll take it apart and do it yet once again with factory o-ring in hand.

HusqRacr pegged the issue early on in this thread!

I've attempted to contact the OP to see if he resolved his issue, but haven't heard back. Hijack over - thx for the help!!
