Seafoam......

[ericem]

Ok, so i plan to just add some seafoam next time my tank is low, and fill up, and pour some in my oil, about 50% in the oil and fuel tank. Is that enough? Is it going to get everything in the engine nice and clean, hehe. Is there somewhere else i should inject it instead?

just make sure you change your oil right after you put it in the oil (run for a few min but not long term)

It may cause oil leaks if your seals are old

[ericem]

really? I thought seafoam doesnt eat seals. If i run it in the oil and gas tank, is that enough?

[fnlyfnd]

It doesn't eat seals. Thats left for the polar bears.

 

It does clean all the crap off the inside of the engine, which is most likely sealing your seals from leaking.

ic, so what should i do? lol. If i put it in my oil and gas is it ok though? Will it make it idle smoother, and reduce vibration when i take off?

Doubtful. Seafoam is best used when sucked directly into the intake and run inside the crankcase. Running it in gas dilutes it too much to be of much use.

 

I don't know how crappy your car idles, but it'd have to be idling really crappy in order to mandate seafoam's use. And, if you're getting vibration during take off, I highly doubt it's due to dirty engine.

ya, probably the rubber mount eh? WOuld be nice, but its kinda off like hesitation, and most likely it wont fix my idle problem, it doesnt idle, seriously and shake the car, i just know the engine is running. like from time to time is idles harder(without ac on). SO though the intake eh? How do i do that, and it if it is done through the intake do i need to change the oil or anything.

If done through the intake, you don't need to change the oil because the seafoam isn't getting anywhere near the oil. You're using the seafoam like gas...igniting it as fuel and burning it. Via its burning, you're cleaning out the cylinder combustion chamber and intake tubes.

 

I fed it in through the PCV valve. I undid the pipe leading to it and stuffed in a tube attached to a funnel (Into the valve itself, not down into the crankcase!!!). Then, I got my dad to hold the idle up while I poured it in SLOWLY - it makes the car really chug when you throw stuff in the system that isn't gas. You'll know you're burning the stuff when your exhaust gets very smoky. If your exhaust is black at first, you'll know that you're cleaning out what was a dirty system. Then, I'd just use it until you get white smoke, then you know the inside is clean. If it's always white or light grey, then you know it wasn't really that dirty in there in the first place.

 

Boxer engines are known for getting a little carbon buildup around the cylinders courtesy of combustion. But, it depends on the kind of gas you get, where you drive, how low you drive the tank to, etc.

thanks, so just atach a tube to the pcv valve, and pour the seafoam. ok, and just let it idle right? Or tap on the pedal a bit.

[fnlyfnd]

Manrius, you mentioned "...how long you drive the tank to..."

 

What does that have to do with the buildup of carbon in the engine. Not knocking you, just curious as I would have never thought that would have anyhting to do with it.

1) Use the search function. It's been discussed here many times.

 

2) Read the directions on the Seafoam can.

[ericem]

ok, i did it, runs way better, and my rear wheels spin for some reason now :banana::banana:. THere was black smoke at the beginning, but then it turned pure white, and i pored some in the gas tank, and now it run way better, and that vibration when taking off is gone, but off course, i can still feel a little vibration from the engine,while idling. All i did, was unplug the hose, from the pcv valve, and aim it up . I just let it idle, though. And there is 91octane fuel i the car and about 60% of seafoam can is in the gas tank. THat odd to fix her up. Thanks guys.

Drive the tank down to near empty and you have a greater chance of drawing in dirt. This dirt makes the combustion of fuel not as good as it could be - and bad combustion causes carbon buildup.

 

Rare that it happens, but it can. Usually you gunk up the pump sock before you start getting really bad carbon build up. Of course there's going to be some buildup just from the nature of explosion.

good to know, time to change my habits.

I would have thought more moisture would get in the engine, but not dirt, i mean the fuel filter should protect it from that. Seafoam is my friend guys!

Glad it worked out for ya. Did u turn off your car after you sucked in the seafoam for a lil while. You should suck it in (car will smoke) but then turn it off for about 5 minutes, restart it and rev/drive around. Make sure this is done on a hot engine

what? lol. All i did, was turn it on and pour the seafoam through the pcv valve, then shut it off. Poored some in the gas tank. restarted, and drove around.

[fnlyfnd]

you should pour it in, wait 5 minutes then drive around and smoke everyone out.

 

Did it smoke when you drove around?? or just when you were pourng it in

while i was poring it in my dad was watching and i saw smoke.

[fnlyfnd]

From what I understand and did myself is to suck it in, but to be careful as to not let it smoke to much while its sucking. After you have sucked the amount desired in with minimal smoking, turn the car off. Let it sit for a few minutes, then turn the car on and drive around. Now when you drive around it will smoke for maybe a quarter mile.

 

This is all on a hot engine BTW.

I didn't drive it around at all when I did it. I just sucked it in via the PCV valve while I got my dad to hold the idle up so it wouldn't stall out.

[fnlyfnd]

You don't need to drive around, you could just rev it in your driveway. The key ingredient is turning the motor off to let the seafoam go to work on the build up.
