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 The previous version was outdated and no longer supported.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

New problem....coolant was gray when I checked it

The oil looks sorta OK. Hard to tell looking through the window. I'm looking for opinions, suggestions and how to. I suspect it may be the head gasket. :(

If so, is it difficult to change?

I am not sure what kind of coolant is in them but my 511 was the same way after a few rides . It looked more like mud that coolant
 
Mine didn't look like any coolant I had seen, kinda grey, so I changed it. Now all okay.

Have you ever re-torqued your head bolts? Mine were loose 2 different times, but one time was due to a high heat incident.

The head gasket is not too hard the change out, I left the engine in the frame and used vise grips to remove the cylinder studs, which is not recommended but it worked OK for me.

I'd change out the water pump seal first to see if that would cure it, here's a way to retain your cam timing when you remove that water pump shaft.

Really? What happened? Did you just flush? And if so how is it now? What kind of coolant are you using now

I flushed mine completely and filled with a 50/50 pre-mix I picked up from a local motorcycle dealer. It's a bluish green. Is there a specific coolant I should be using? I checked the oil with a visual inspection through window and I think it looks ok. I'm about due for an oil change anyway and will do that this weekend. It's been running great and my Trail Tech Vapor computer monitors the engine temp. It hasn't gotten hot. I'm afraid of running it though for fear of damaging the motor.

What should I do.

Thanks!

Can oil and water swap through the water pump??

Good lord ! Now my leaking radiator cap has me worried !

When my head gasket was leaking on me, I actually blew steam from my rad cap on a single track ride, I thought it was just a loose fitting cap, I bent the tangs on the cap in a little tighter, making the cap harder to put on, but a much better seal. I continued running hot until I replaced the head gasket. My coolant never looked murky, there was never any water in my oil, it was a very small head gasket leak.

Good to know. I just spoke to a friend of mine that worked for Trinity Racing. He's been turning wrenches on all kinds of bikes for years. He's not real familiar with the Husky motors but he said that if it was a leak at the head gasket it be running very hot, probably farting out smoke and running like crap, etc. Since it's running fine and not overheating he thinks it may be the water pump as OlderHuskyRider suggested. He told me to change the oil. He said it will be all yellow like baby poop or something if there is water in there. If not he said to just ride it and check it after the ride. If the radiator is contaminated again then probably the water pump seal.

White smoke and running like crap are blatant signs of a blown head gasket. Head gaskets can develop small leaks and not show the "blown" symptoms,

When my head gasket had a tiny leak, the bike DID run hot, and small amounts of coolant kept disappearing, but the bike was actually burning the small amounts of coolant it was getting and running great, with no white smoke and no bubbles in the rad stream, also, no exhaust gases present in the radiator (I checked).

When I had my bad water pump seal, I had milky oil non-stop, I'd change the oil, the oil showed clear as honey in the sight glass, then take 1 ride and, bam, chocolate milk for oil. I rode it a few times like that, until I got my parts.

In case you didn't see my post edit above, here's a way to retain your cam timing when you remove the water pump shaft.

HG fire ring breech indicators: compression gasses in the coolant, causes pressure in the cooling system, forcing coolant out past the cap, subsequent o/h. HG water jacket seal breech: after shut off or during high stress runs the coolant can cross-over into the oil drain back gallery causing intermix. (creamy frothy milk shake etc)

Oil in coolant: seal failure somewhere. gallery casting crack causing pressure bleed off into cooling system. check for low oil in crankcase and milk shake in the radiator/overfull cooling system. if this happens find the leak, correct condition and flush the whole system after with hot soap and water. highly recomend replacing all contaminated rubber items as oil degrades same and causes seperation and swelling.

Dirty yukky coolant: hoses yuking it up, reaction between coolant and hoses or other materials, poor quality coolant. flush with hot tap water followed by distilled water a couple times to purge until its clean and clear, drain completely and go to a premium coolant and rediagnose. see our sponsor Zip Ty for FX+. last coolant you'll ever need to use.
 
ya know its weird. since '09 ive seen a trend in crap coolant coming from overseas- is there a new law that says it cant have a PH higher than boar pee or wtf????. seriously. the stuff that came outa my '12 300 was nasty and the hoses did not dig it, pull one off a spigot and see. my nose dont dig it either. at all! my cooling system is gettin' a complete overhaul.

getthat mud outa that system NOW, yank and scrub the hoses and everything you can in hot soapy water and flush it like crazy. dare ya to sniff one of them hoses man! woof!

also- dont let foamy oil sacre ya. milk shake? maybe- if yer outa coolant. foamy and bubbly in the sight glass? normal. that motor will also condense a lot of water so...dont go to heck in a hand cart if yuo see some streaks in the drained oil or sight glass. it all evaporates whne yuo ride it.

Thx Pvduke. I needed that. I'm rolling through Xanax like Tiger Woods rolled through women. I'm gonna drop the oil tomorrow and look at it. Fill it back up and go for a ride on Saturday when i'm off of work. Ride it about 15 minutes and then let it cool and check the radiator and oil.
 
no worries boss man. just get that cooling system spotless before ya do anyting and yank the hoses and wash them out my hands still stink from mine woof its gnarly. dont want that crap in there anylonger than nec. leme now how it goes or if ya got any issues. braaap! :D
 
I remember playing "name that crud" with my WR.
