Excuse the dumb question...

When you guys are talking about carb problems from old "o-rings", are you talking about the ones internally in the carb, or the manifold sealing o-rings?

I understand my 1100E doesn't have the manifold o-rings... what are the symptoms you will experience when the "internal" o-rings are deteriorating?

Actually, it's kinda hard to find a "dumb" question, but "smart" answers are a dime a dozen. :D

Both sets of o-rings can cause problems. If the internal o-rings are leaking because they are cracked, the symptoms will vary based on which o-ring is causing the problems. Leaky o-rings at the inlet needle valve (float valve) will allow gas to bypass the valve and overflow the float bowl if the petcock does not fully shut off. Leaky o-rings around the enrichener valve ("choke") will lean out the 'choke' mixture, possilble making it harder to start. Leaky o-rings around the idle mixture adjust screw will wreak havoc with your idle mix settings, usually leaning it out. The other set of o-rings that will come in the kit from cycleorings.com will be for the fuel transfer tubes between the carbs. If they leak, they just drop raw gas on the back of the hot engine.

If your engine had the manifold o-rings, they would likely leak enough to lean out the mixture just before it goes into the engine, causing idle problems and overheating problems. You don't have those o-rings, but you should still make sure that your manifold tubes are pliable enough to seal well. Old tubes will harden and shrink, making it very hard to get them on and off, if necessary.

Okay, let's venture out of the world of two-wheelers.

My wife drives a 2000 Toyota Corolla. It has about 123,000 miles on it, and she commutes 35 miles a day (RT), plus we tend to take long trips in it cuz it gets better mileage than my 99 CR-V.

For the last few months slash maybe a year we've been adding oil to the Corolla... to the point where we add a quart or more a week.

There's no quart of oil beneath the car, and my wife researched it, found that its a common problem with that era of Corollas... consuming and burning oil. Sludge builds up.

As she was describing her research to me, all I could think of was SeaFoam.


So whaddya think? Would it hurt to toss half a can of SF into the gastank? Woudl it hurt to toss half a can into the oil? Could it possibly help? Or is it time to go shopping for a replacement cage?
 
I use sf in my cars a lot. I think its a great idea. Cleans out the system for smoother operation (fuel injectors, etc.)

Just do it;)!

seafoam is alot cheaper than another car. i would try it first.

i've used seafoam in several of my cars, never had any issues. seemed to helpe mpg and such, just like most good fuel injection cleaners. definitally try it first.

Hadn't thought about using it on my stator. Maybe I should've before I replaced it. ;)

Seafoam brought a dead battery back to life for me, just popped the cap and poured some in...good as new :rolleyes:


For those that can't tell I'm being sarcastic, I don't recommend seafoam in your battery.

125k is not that much for a Toyota, but you best start looking for a new car.:p

You can use it in the crankcase. It probably won't help unless you have stuck rings and whether it will help that is debatable. It's more than likely valve stem seals. Does it smoke a little when first started? Have you done a compression check?
 
i just replaced my oil, and poured about half the bottle in with the oil, i went on a 35 mile run today

my question though, is it ok to let that stuff run in it for a week (about 100 total with my commute), or do i need to change the oil ASAP?

Hi Mr. tjhenry,

Half a bottle is too much. About 2 oz. should have been plenty.

I seem to recall (I don't know if I read the instructions on the can or if I read it here in the forum) that you can run Seafoam in the crankcase for about 50 miles. Then you must change the oil again.


Thank you for your indulgence,

BassCliff
 
seafoam use

seafoam use

this stuff is a carbon cleaner, not a carb/injection cleaner, the best use for it is to use ported vacuum to the intake and raise the rpm for a good draw of the mix, this will make the engine smoke like hell as it heats the combustion and softens the carbon-which is partly the smoke. it works great to clean the intake and the exhaust valve stem sides of the valves or valve face, the ads you see for techron and seafoam for improving the fuel economy is because the intake and exhaust valves are clean and flow the intake and exhaust charge easier.the best carb/injector cleaner-without disassembling, is a carb cleaner by name-but this stuff is quite aggressive and should be sprayed right where needed only-so best to take it apart to clean correctly.my .02 on this stuff

As I have previously mentioned, I have run SF in the crankcase to clean out gunk. The last time I put about half a can in and rode around for about 1000km over a 5 or 6 week period. Absolutely no issues but a whole bunch of crap came out when i changed the oil.

When I first became aware of the stuff I was curious about running it in oil so I called the manufacturer and managed to get to talk to someone in the lab. He confirmed to me that as it is a petroleum based product it is perfectly safe for gas and oil.

I'm a big fan of it.....but I don't get paid to say so:D

Cheers all,

The problem with running solvent in the oil is that all the oil/solvent mix doesn't come out when you change the oil.
