Does anyone know of anything to dissolve the hard carbon deposits in the exhaust passages of heads? Nothing I've tried works well (carb cleaner, engine cleaner, simple green) and I can't get at them to scrape it out (if I actually wanted to risk scraping around the valve seats).

Steve

Have you tried soaking it in some Sea Foam?

Ha. I thought of that, but wasn't sure it was going to work and didn't want to find out it didn't for the money it costs.

Steve

You mean Sea Foam is expensive?

I'm not sure it'll work either, but it does seem to be good at cleaning up carbon deposits at least on the intake side when you run it through an engine.

I get Seafoam from the gas station that my 'lil sister is a manager at.
She alway's asks what people do with it, and that no one ever buys it.
I get the 16 oz. cans for $2.99. I have 3 of 'em on my car "fluid" shelf in the garage.
So anyway, no, it's not expensive.

It's like $7 here!

Dah!!! Its not fair!! The Canadian NAPA guy I talked to had never heard of Sea Foam, and apparently being able to bring stuff across the border from US NAPAs is still in the works.

It looks like I'm going to have to do the roadtrip into Buffalo vrg3, as I'm out of ideas otherwise! Unless customs will let it across the border.... Hmmm....

But back on topic, the deposits are that hard? Wow! Yeah, it sounds like they need to soak in something strong then.

I took most of it off the combustion chamber with a brush and Simple Green, but I can't get in the exhaust passages and engine spray cleaners don't do much - I'd have to soak it for days and still have to get something to scrape it or wipe it off. It's ~ .01" thick.

I had a thought: it's possible that I can have my sister order a bunch of Sea Foam from whoever they get from at their cost and then send it to whoever might want some.
I haven't thought about it any further than that, but it might save people a bunch of money. Like I said, I pay $2.99 US for a 16oz. bottle.
Just a thought...

i'd buy some

Cross border group buy!!!!

I'd be in. We would still have to figure customs out though. I keep wondering why Sea Foam says they don't sell online, and whether that would pose a problem at the border.

there's a few places that sell online, I just figure it would be cheaper and faster to get someone on here to pick up a case and have it shipped.

Whenever I've gone to Canada its like Monty Python and the Holy Grail - What is your name?
Where are you from?
What is your favorite color?
OK, off you go...

Would they check or even care about a can or two of Sea Foam? Would they even know where it came from?

Steve

I can't see it being a problem at all. The only issue I can think of is not being able to ship pressurized cans cross boarder...

its not pressurized though

But it is inflammable and under certain conditions explosive.

And if you have more than a certain quantity of it they may suspect it's not just for your own personal use.

But, yeah, when I last crossed the border I was never even asked my name or for ID, in either direction.

I'll probably try smuggl... err... bringing some across the border sometime this month. I just need to find the time to drive down to Buffalo.
