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 The previous version was outdated and no longer supported.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

SM610 water pump housing leak

Hi All,

So I've recently redone my timing chain and in the process, replaced the water pump housing gasket. And this is where my problems start. I simply cannot seal the housing properly. I have tried the OEM gasket (purchased from Hall's) on it's own. It leaked out the top RHS of the housing. I tried the gasket with permatex ultra black on both sides (followed permatex guide to the 'T'). And it sprung a leak on the LHS of the pump (see yellow arrow)

I then got rid of the OEM gasket and used permatex on it's own making sure the suspect area had plenty in there. Guess what? It leaked again in the same spot (yellow arrow).

Now these leaks are very slow (1 drop every 2 min) but I'm lost as to why it's happening. I have noticed that this region (yellow arrow) is where the head cover join is. Should I put liquid gasket along this 5mm or so of join as well? Should I build it up on the outside of the housing?

I know now that I don't want to use the liquid gasket without the OEM one. It makes it very challenging to get the water pump off again. So if I clean the permatex off the new OEM gasket, any reason I can't re-use it seeing as it's still fresh.

Any help would be really appreciated. This persistent leak is extremely frustrating!

Cheers!
 
Wow. I had no idea that the gaskets were such a problem to seal the water pump. Thanks for the update, much appreciated.
