Default Found this in my Rad fluid

Went to check it today and stuck my finger in and got this :-( any ideas? Im gonna flush it tomorrow. Doesn't feel gritty. Looks bubbly and like a rootbeer float? I have more pics. But Photobucket is not letting me sign on :-(

Check your oil to see how that looks. Could be headgasket letting oil into coolant and visa versa. Hard to tell from the pics.

That does look like Mousse. Mousse will float up on coolant after being beat up by the water pump.

Does it feel oily? Does it smell oily?

Could it be the Subaru Coolant Conditioner additive?

Chocolate mousse lookin' stuff in coolant = blown head gasket...assuming it's not sludge/dirt accumulated in bottom of your overflow tank. How's the oil/dipstick look (may or may not show anything with HG leak)?

Where are you in the southeast?

Definitely looks like you have some head gasket issue, Id get a block test done on it and get it flushed out. Do you have any issues with overheating or lack of interior heat from the vehicle?

OK, so I did alot of searching on line about blown head gasket. Did some test. Then this AM I drove to my friends shop. He looked at it and knew right away. I thought you would need to do a leak test or compression check. He said, I could if you want, but here's a few signs.
1)The dark milky bubbly fluid in the radiator. It also feels oily
2) Your radiator hose feels like its about to explode.
3) When the car is running your rad fluid is bubbling. Thats air getting in.
4) When you turn you heater on in the car, I can smell anti-freeze in the vents.
My friend has been doing this for 40 years. So I guess he would know without a test. I just thought with a test you would know for sure. But all the searching I did, those were some of the signs. I guess the $900
he said it would cost is making me wonder. He said about $150 for the gasket kit and the rest on the work. He said the engine has to be pulled. Its gonna take about 5 days. Just because of all the other cars he has to work on too. I went to Pepboys to see if they would do a leak test or compression test. "What kind of kar U got?" WRX. "Its got that Turbo that whistles" Um... "we don't werk on dem cars, ya need to go to a speedshop" Ok thank god

smelling anti freeze in the vents on heater isn't a head gasket, that is a heater core leaking.

but what you have certainly looks like oil in there, and yes, it is that expensive to get it fixed.

It does it with the AC too. Don't know if that makes a difference. I should have made it clearer. Yeah, Im starting to realize its gonna cost big money

I'm definitely not a longstanding mechanic, but I really have to agree with Scotty on this one.

I had similar looking material in my coolant resevoir and at the coolant inlet. It was particularly nasty in the reservoir where a combination of what I presumed to be water wetter and the Subaru coolant conditioner had congealed to form a rubbery, chunky looking mess. I had to flush the cooling system to get all of the chunks out. Needless to say I had to ditch the water wetter...

If anything, get a second opinion and look for SURE signs that its a HG. Not sure if your friend is in the know about the coolant conditioner that Subaru uses, but I'd definitely ask if there's a possibility that it could be just some reminants of that.

Well I went to get 2 more opinion.One was a tuning shop. They do alot of subys. He told me that usually when you have a blown gasket, you miss fire, you can overheat, white smoke comming out the back. The other shop was Irish Mikes in Orlando. They have a Suby race team and what not. Anyways, I had an engine block test done. Someone mentioned it earlier. They put this fluid thingy in your radiator. It starts out blue. If it comes out yellow, Blown gasket. Everything came out fine. He said it looked like something was put in, like mixed rad fluid or another fluid, rust, gunk. He said sometimes you might top off and you might have used a different color fluid, Yellow, blue, pink, red, green. The chemicals might have mixed and reacted like that. He said alot of manufactures use certain colors just because that how they wanted it. Motorcraft red, VW pink, and so on. So you have to be careful .He said my thermostat was pretty bad with gunk and other crap. He said I needed to have evetrything flushed and that should do the trick

Edit: oops, I missed your last post where you say you had the block test before posting the oil analysis suggestion below. Original post:

Get your oil analyzed from Blackstone Labs. Their analysis will pick up coolant in the oil. Call/email them for a free sample kit, then change your oil and take a sample of your old oil as it's draining into the pan. Send this and something like $20 (or credit card number), and you'll quickly get a slick, nicely prepared report from Blackstone like this:

If its DIY, then get some white vinegar to help knock some of that junk loose when you flush.

I would strongly advise AGAINST using any vinegar in the cooling system!!!!!!!!

the block is aluminum and vinegar etches aluminum.......it is, really, unnecessary......use filtered water----NOT tap water!!!!!! and run a couple cycles through it and then re-fill it with coolant/water mixed
