The oil consumption problem on 1ZZ-FE motors is caused by gummed up oil rings. The build up of half burnt oil causes the rings to stick in a contracted position inside thier ring groove on the piston. This causes them not to come in full contact with the cylinder walls, causing oil to get by them & to burn off. In fact once it starts, the problem makes it self worse.

The solution is to put a specialized solvent designed for this purpose into the oil. The solvent is supposed to disolve the crud that holds the ring in & free it up. If it works, you will be good as new.

As soon as I find out what the name of the solvent is, I will post it.

[Linked Image from seafoamsales.com]


100% Pure Petroleum
Use in All Engines in All Seasons
2 Cycle, 4 Cycle, and Diesels
Treats 3 Critical Areas: Gas Tank, Fuel Systems, and Crankcase


-Cleans fuel injectors
-Cleans carburetor jets
-Cleans carbon
-Stabilizes fuels
-Upper cylinder lube
-Removes moisture in fuel
-De-icer
-Frees sticky lifters
-Frees sticky rings
-Removes moisture in oil
-Cleans P.C.V. systems
-Cleans catalytic converter odors
-Oxygen sensor safe

How Many Mechanics Use SEA FOAM
In Tune-Up of 4 Cycle Gasoline Carbureted or Fuel Injected Engines
Autos, Trucks, and Tractors


1. With engine warm, slowly pour 1/3 to 1/2 pint through carburetor or throttle body throat. (If vehicle is port injected slowly pour SEA FOAM through direct manifold vacuum line that will feed all cylinders, possible sources are P.C.V. valve or brake booster line.) This will pull SEA FOAM down on top of the pistons and to the back of the intake valves to dissolve carbon. Turn ignition off. Restart engine after 5 minutes. If severe carbon build up is apparent, use more Sea Foam as previously directed. Make sure exhaust is well ventilated when using Sea Foam in these various ways as fumes will be extreme for a short time.

2. Pour 1/3 to 1/2 pint into oil crank case to clean rings, lifters, dirty parts and remove moisture.

3. Pour 1/3 to 1 full pint into fuel tank to clean injectors, carburetor jets, fuel lines and remove moisture.

4. Immediate Results: Smoother idle, increased R.P.M.'s better throttle response and improved performance. See label on can for detailed results for use in each area.

FUEL TANK, CARBURETOR, INJECTION and OIL CRANKCASE.

For Peak Performance, Use SEA FOAM Every 2,000 to 5,000 Miles

-A 100% pure petroleum product for use in all gasoline and diesel type engines, both 2 and 4 cycle. OXYGEN SENSOR SAFE.
-Cleans dirty engine parts internally by removing harmful gums, varnish and carbon. WORKS AND PERFORMS INSTANTLY.
-Removes moisture from oil crankcases and fuel tanks.
-Stabilizes and conditions fuels. Use for engine storage.
-Cure hesitations, stalls, pings and rough idle due to carbon buildup.
-Helps pass emissions test. EPA Registered.

When Used Thru Injection or Carburetor

-Cleans carbon build up
-Cleans intake valves and pistons
-Gives smoother idle
-Cleans catalytic converter odors
-Cures hesitations and pings
-Restores power and pickup
-With warm engine running, SLOWLY poor 1/2 pint through carburator, throttle body or direct manifold vacuum line that will feed ALL CYLINDERS. Possible sources are P.C.V. valve or brake booster line. Turn ignition off. Restart engine after 5 minutes. Be sure exhaust is well ventilated. Fumes will be extreme for a short period of time.
-For use in injector cleaning machines, use 50% SEA FOAM and 50% fuel.
-Fill diesel filters with SEA FOAM to clean injectors fast.

When Added to Crankcase (Oil)

1. Frees sticky lifters and rings
2. Increases R.P.M.'s vacuum and compression
3. Cleans dirty parts
4. Removes moisture
5. Cleans PCV valve systems

One pint treats 10 quarts of oil (avg. 1 1/2 ounce per quart).

-When Added to Fuel Tank
-Cleans fuel injectors and carburetor jets
-Cleans carbon as you drive
-Lubricates upper cylinders
-De-ices and removes moisture
-Diesel full conditioner and anti gel
-Stabilizes fuel

One pint treats 8-25 gallons of fuel (average 1 ounce per gallon).

It's injection. Carburetors are found on much older cars.


On another note, I went looking for this stuff a while ago and couldn't find any. I'll keep looking though.

You can pour it into your PCV hose to get it into the engine, through the oil filler cap to put it into the oil system, and put it in when you get gas to put it into the fuel system.

I just did it. Thanks a lot. thumbsup
(I got the SeaFoam from NAPA Auto Parts.)
But one more question.. How come when I take the PCV hose off, my engine can't get a start?? therefore, I put half bottle of seafoam into the injection when my engine is off, and then put everything back. Finally, start my engine. once the engine get a start, lots of smoke come out.. wtf
Is that OK? confused

I got this stuff today, I put it in my oil and gas tank. It's incredible stuff! My RPM's idle at 800 rpm like it's suppose too! Better throttle response and runs way smoother overall!

I'm very happy! thumbsup

The reason the engine won't start is because it has a huge air leak with the disconnected PCV hose. This lets air in past the MAFS, and the engine can't match it with fuel since it has no clue what's going on. The best way to do it would be to have someone else start the engine and sit inside the car. Unhook the PCV hose and plug it with your thumb, having the person inside rev the engine if the revs drop while you're doing this. Then, take your thumb off and pour in some Seafoam, making sure the person inside is still revving when necessary. After that, plug up the hose again and wait a few seconds before putting more in. You want to add a little SeaFoam at a time, not all at once, so you'll go through this process a few times.

And yes, once the Seafoam gets into the engine and loosens all the buildup, it will burn, causing black smoke to come out the exhaust. Don't worry, it's a good thing. smile

On the site I posted, $7 for a bottle, $36 for a case of 6, $69 for a case of 12, and $132 for a case of 24. If you're ordering online, I'd definitely get one of the cases, since you'll save a lot of money vs buying individually when you need them. You'll most likely be using this product again in the future, anyway. smile

Yah, but does anyone have any actual experience with Seafoam working for this particular problem?

The stuff Toyota used wasn't sea foam. I forget the name & I will have to ask again. Basically they added it to the oil & ran the motor at 2000RPM for 15minutes, drained the oil, put in fresh & did it again, drained the oil & did an oil & filter. The rings freed up & the engine burns very little oil now. thumbsup

okay i just bought some of the seafoam at my local autozone... thumbsup 2 for $9.99

where do you use it again? gas tank? and wat else? something about PCV hose? where is that?

oh and do you need to have a full gas tank before adding the seafoam to it?

some should make a "how to" on this?

Put it in your oil and gas tank. It shows on the can the recommended amount of seafoam to use for each task performed. As far as the PCV hose, I couldn't tell ya. Someone should provide pics. thumbsup

I'm really wanna know what is the name of that product, because I just did a compression test today, and I'm sure I got the ring problem. Could you find the name of that product for me? I appreciate. smile

Oil ring issues don't show up on compression tests. I was getting between 185 & 190 over all four. The two compression rigs should hold the compression, the oil ring (3rd ring) is the one that gets stuck.

I know, I gotta ask the dealer again.

I've been losing about 1 qt of oil every 1,500 miles. After putting Seafoam in my oil, I checked my oil after 2,000 miles and it's still on full. It must have free'd up the rings spineyes

"If adding oil helps the compression, it is likely that the piston rings and/or cylinder bore are worn or damages."
This text is from the "ENGINE MECHANICAL - COMPRESSION" in "TOYOTA REPAIR MANUAL", you can find it from the "Technical" link in "gallery" link on this website.

If you have stuck oil rings they will not effect a compression test.

If you have worn out compression rings, adding oil may improve your compression.

These two statements have nothing to do with each other

Hey all! I'm a new owner of a 2001 celica with 122,xxx miles with the infamous 1zz-fe engine and am experiencing a slow amount of oil consumption. smirk I am wondering if the sea foam is the first route to take in cleaning up the rings?

To dissolve gums and vanish on piston rings and valves, try MOTOR MEDIC MOTOR FLUSH.

https://www.njsupply.com/MotorMedic-Motor-Flush-MF3_p_121201.html

It's sold in WALMART for $4 a quart. I used half a quart and idled engine 10 minutes then drain oil and replace filter. It dissolved lots of gums and vanish that the other chemicals did not. The drained oil was black and thick like tar after 3 flushes.

I solved the low compression in cyl 1. All cylinders have about the same compression and engine is smooth like new.

SEAFOAM did not do anything for me but potentially can contaminate Oxygen sensors and Catalytic converter, causing SMOG problems.
