Many of you are familiar with
seafoam, some have no idea what it is.
Well, for all those that are interested, seafoam is multipurpose, 100%
petroleum product you can pick
up at any
local auto store (napa, advance, autozone, etc). It is used to clean
carbon buildup from your engine, clean your injectors, clean your oil
and a whole lot more. To familiarize you with the products, this is
what i am talking about:
Uses of Seafoam
i would first like to state for the record that seafoam is NOT a
power adder. all seafoam does is clean out the gunk inside your engine
and injectors. this will do nothing more than restore any
horsepower/fuel economy you have lost due to years of dirt and grime
inside your engine. any power you pick
up along the way is because it has just been supressed by the filthy engine and is now free again.
if you are losing power and mpg due to carbon buildup, if you are
experiencing pinging and if you’re having trouble passing emissions
test, seafoam may be your answer (yes, seafoam will actually reduce
your emissions if carbon buildup is causing dirty exhaust fumes!).
feeling the pinch at the pump lately? well, seafoam can be used to pick
up a few extra mpg you have lost over the years and reduce or elimiate your engine ping by cleaning out your cylinders!
What You Need to Seafoam Your Engine:
in order to maximize your engine’s fuel economy and performance, you
should do a full engine treatment. in order to do so, you will need a
few things:
- 2 cans of seafoam (1st picture above)
- 1 can of seafoam deep creep (2nd picture above)
- flat head screwdriver
- pliers
- 1 long, skinny funnel
okay, now that you have all the necessary tools to complete the job, let’s talk about how to use
seafoam:
How To Seafoam Your Car:
Part One: Injector Cleaning
this is the easiest part of the process. simply drive to the gas station and
completely fill up
your tank with 91+ octane gasoline as usual. take 1 of the 2 cans of
seafoam in the requirements above. this can of
seafoam will be poured
directly into your gas tank. now, seafoam makes a great product but
they didn’t think too hard when they designed their can. you need a
funnel in order to dump it into your gas tank. do not try to be cool
and try and beat gravity by jamming the can into your gas tank. i tried
that. all i got was a car that smelled like gas and wasted seafoam on
the ground. take the long skinny funnel, put it in your gas tank, shake
the can of seafoam
up and pour the
entire can of seafoam into the tank. then, take your car for a nice
ride so the seafoam swishes and mixes in your gas tank. the seafoam
will clean out your injectors nicely. try and run this tank pretty low
before filling
up so you don’t dilute the mixture with more gasoline. this way, you get the maximum cleaning power of seafoam.
Part Two: Cleaning Your Oil System
as you all should know, f-bodies require 5.5 quarts of oil. seafoam
is to be added directly into your crankcase in order to cleanse the
oil. yes, you heard me, you’re pouring a foreign mixture directly into
your engine oil. this can be scary for newbies. never fear, seafoam is
100% petroleum. it is as harmful to your engine as water is to your
skin – not harmful at all. the correct measurement for seafoam is 1.5
ounces per quart of oil in your crankcrase. simple math tells us:
(1.5) X (5.5) = 8.25 ounces
a can of seafoam is 16 ounces, so for simplicity’s sake, we’ll add half a can directly into the ENGINE OIL spout.
NOTE:
i recommend pouring the seafoam into your oil when the car is cold. i
would not recommend pouring a room temperature liquid into 200+ degree
oil after the car is hot. last thing you wanna do is shock your valve
springs.
run the seafoam in your oil for NO MORE THAN 250 miles! seafoam is
very agressive. your next oil change will be black as satan’s heart and
likely thicker than usual. i would not recommend running this oil very
long in the car as your oil filter is going to have quite the time on
its hands and the oil won’t be in the best of shape afterwards. i’ll
say it again.
change your oil less than 250 miles after you put seafoam in your crankcase!
i personally recommend running it 100 miles, then changing your oil.
that should be plenty for the seafoam to get most of the gunk out.
Part Three: Top End Cleaning
here comes the fun part: cleaning
the engine
internals! NOTE
unsecured loans: park your car in a VERY WELL VENTILATED area for this
step as high amounts of toxic fumes will be pouring out of your car.
as you recall, we have half a can of seafoam left. this half a can will be used to clean out your
cylinder banks. in order to do this, we need to locate a vacuum line to directly feed the seafoam into the engine. the favorite
vacuum line is the brake booster line. for those unfamiliar with the brake booster, here is what it looks like:

the brake booster is the big, black saucer shaped object behind the
brake fluid holder against the driver’s side firewall in case you can’t
tell by the picture.
we will be sucking the seafoam into the brake booster hose marked by
the red arrow. (note: some people prefer to suck the seafoam in
through the PCV line. this is also acceptable, although i have never
done it.)
first thing you wanna do is start the car and let it warm
up until the engine reaches closed loop. basically, start your car and wait for the engine to warm
up
to normal operating temperatures (5 – 10 minutes depending on outside
temperature). after the engine is nice and warm, turn the car off. now
we’re going to disengage the brake booster line.
for this, you may need a pair of pliers and a flat head screwdriver.
there is a little metal clip holding the brake booster hose to the
brake booster. you want to take a pair of pliers, compress the clip and
slide it down the hose a few inches. now that the clip is out of the
way, you need to disengage the brake booster hose. this can be a bear if
you’ve never done this before. my car had 80,000 miles on it when i
seafoamed it and that sucker was stuck on there tight (it’s a vacuum
line, it’s glued by high pressure). you may need to take the flat head
screwdriver and jam it into the vacuum line and wiggle it off the brake
booster. this may take a while. it took me a lot of pressure to get
the hose off the booster. you may have to pull pretty hard.
once the hose is off, you’re gonna want to find a small funnel that
will fit into the brake booster hose. i do not recommend simply jamming
the hose into the seafoam and letting the engine suck it
up. this makes it very hard to control the amount being sucked
up and could flood the engine far too fast causing it to prematurely stall out.
now that you have a funnel jammed into the brake booster hose, start
the car. you’ll notice your rpm’s are very high, likely around
2000-3000rpms. this is because your brake booster hose being
disconnected is causing a massive vacuum leak. you’ll be able to feel
the engine sucking air down the funnel.
at this point, you have half a can of seafoam left (8 ounces). you
should, in your head, divide that into three equal parts. you’re going
to want to SLOWLY pour the first two thirds of the seafoam left in the
can into the engine via the funnel. the engine will start
bad credit loans to sputter
and choke as you pour in the seafoam. you DO NOT want your engine to
stall out. go as slowly as possible pouring the seafoam into the engine
as necessary so the engine does not die. do this for the first two
thirds of the mixture. with the final third of the seafoam, quickly
dump it down into the funnel. the idea here is to stall out the motor,
suspending the remaining gulp of seafoam in the cylinder banks (don’t
be alarmed if your engine bay is smoking the entire time this is
happening). if your car does not stall, quickly run and turn off the
key.
do not start the car for at least 15-20 minutes. we want the seafoam to soak in the
motor good and hard to get all that nasty carbon out of the engine.
while the engine is sitting and soaking, with the key out of the
ignition of course, get that bottle of seafoam deep creep i told you to
buy.
seafoam deep creep is to be sprayed inside your throttle body. disconnect your hose running to the throttle body so your
throttle body
blade is showing. get a friend to push down on your gas pedal so the
throttle blade opens. if you don’t have a friend at your disposal, a
brick or something will do just fine to hold the gas pedal down,
anything to keep the throttle blade open. again, your engine is to be
OFF during all this.
once you can see inside your throttle body opening, spray seafoam
deep creep into throttle body, fully soaking the blades, the bottom,
top, and
up and down into the intake
manifold behind the throttle body. use a good amount of seafoam. don’t
be too conservative, but the whole can is far from necessary. use your
judgement. get it in there nice and deep but there’s no need to flood
anything!
reconnect the throttle body hose, the brake booster hose, the clip
back on the brake booster line and anything else you may have disturbed
during the seafoaming of your car.
now we will just wait for the remaining time to pass before you can start your car back
up.
okay, now that 15-20 minutes have passed, it’s time to start your baby back
up.
this may be a challenge. the engine is flooded with liquid so it may
be a lot harder to start that usual. this is completely normal. once
your car is started, let it idle for a good 10-15 minutes. your car is
likely to smoke profusely. if it does not, lightly tap your gas pedal.
do NOT rev the engine like a madman. when i say lightly tap, i mean
gently tap the rpm’s
up to no more than
1500. a blip is all that is necessary. if it doesn’t smoke too badly,
it’s because your engine just wasn’t that dirty.
after the car has been sitting idling for 10-15 minutes, take the
car out for a spirited drive. the key word here is spirited. you want
to rev your car nice and high and get all that seafoam into all the
valleys of the engine. this is the perfect excuse to completely run the
balls off your car. if you look behind you, you will likely see a long
trail of blue smoke dusting out the entire highway. say good-bye to the
culprit carbon buildup killing your power,
gas mileage and causing your engine to ping.
congratulations! you have successfully seafoamed your car. be amazed
as your car revs faster, your gas needle moves slower, your idle is
smoother and yes, even your exhaust smells less noxious
NOTE: seafoam is O2 sensor safe and will not damage your spark plugs
or catalytic converters with responsible use. this means as long as
you’re not seafoaming your car constantly and using far above the
recommended dosages, you should be fine. it’s probably good to do this
process every 10,000 miles to keep your car in tip-top shape.
