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 The previous version was outdated and no longer supported.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

2014 TE310R WEEPING OIL FROM HOLE BESIDE WATER PUMP

Hi All,
I have searched Hi & Lo & cannot find an issue similar to this:
I have recently purchased a 2014 TE310R (last of the red Italian ones) & the small hole to the left of the water pump weeps out oil on startup & shutdown (most noticeable during those times at least). See hole location below.

I have removed the water pump for seal inspection etc & it seems fine, did not appear to be any cross contamination. I now do not believe the hole is related to the water pump at all. So I then added some air pressure up the exterior hole in question & noticed that it blew out/displaced oil just under the cam gear clamp bracket & above the cam follower rod. (this could be seen as the water pump was still removed)

What are your thoughts? What is the purpose of this hole? All help/advice would be greatly appreciated.
Cheers,
Dwayne
 
I believe it is a drain for the spark plug cavity which has a tube and seals that isolate it from the cylinder head and oil. If any of those two seals are impacted it may weep/drain oil out that hole. Maybe pop the valve cover and check that tube and seals.
 
Hi Johnrg - Appreciate the response.
It does make sense what you've mentioned. The Valve clearances were checked approx 200kms ago, so perhaps the dealer picked up on the O-Ring in the spark plug cavity on re-assembly.

I will have a look tonight & report back.
 
Update - Johnrg you were spot on. O-Ring in spark plug cavity had 1/4 of it totally missing. See the O-ring in question in the parts breakdown below - No.17. Also see damaged version of this O-Ring in my bike. (1/4 totally missing). This allowed oil to pass out the spark plug cavity drain hole.

Wow... Glad to hear and see you found it. This is always my concern with others working on my machines.
