Seafoam?
Hey guys I just bought a bottle of the stuff and I just want a few opinions on it before I dump it into my T/A. (after I get her to start on her own again). Any tips/warnings would be great too.

Re: Seafoam?
yea got get another 2 cans

pour one in the gas tank
take and put a vac line in another can and let it suck up into the engine till it dies, let it sit for a while remove the vac line from the can and start it up (may take a few trys) ......start over, do it over again
last can right before your next oil change pour a can in the oil and ride around the block 2 times or so and then change the oil normaly

Re: Seafoam?
Oh lovely... more money to put into this money pit. LOL
You'll need to help me with the vacuum line, which one is that? How do I identify it?

Re: Seafoam?
Money well spent
When you start it up for the first time it will smoke....alot. This is normal, and quite fun. The more it smokes the more you needed to do it.
All my cars get this treatment every couple of years.

Re: Seafoam?
I'll be the dissenting opinion. It's just oil, alcohol, and naphtha. Gas is already 10% alcohol in most parts. The oil makes a nice smokescreen. You can always pour a little lighter fluid in there (naphtha) if it makes you feel better. I think the effect is more phychological than measurable.

Re: Seafoam?
it will clean your intake real well, they also make a spary sea foam to clean the area before your vac line
or you can just use regular carb cleaner there (throttle blades)
a good vac line to use is the brake booster or the line going to the PCV (un hook it from the PCV and stick it in the sea foam can)
someone with TPI needs to chime in on the best vac line for TPI, im used to carbs and TBI on older V8's

Re: Seafoam?
On TPI I use one of the lines going to the charcoal canister. Better chance of it hitting all of the runners instead of just putting it in the back of the plenum.
It didn't clean my engine very well. 20 miles before a teardown I seafoamed the car. I was trying to not have to tear down.
To me it looked as if the seafoam did nothing to my intake tract.
