This weekend I got me two cans of Seafoam and a can of Seafoam Deep Creep.
I read in one of the Corvette forums that GM sells a top engine cleaner that is nothing more than Seafoam rel-abeled. Most of the Corvette guys do this every 10K miles.
I removed the air intake conduit and sprayed the heck out of the throtle body with the buttefly open with Deep Creep, I followed the instructions and cleaned the intake with clean rags, it was incredible the amount of gunk that came out every time, I used at least 5 rags until the last one came out clean.
Then I proceeded with the Seafoam into the PCV vacuum line and sucked in at least one the cans of Seafoam while trying to maintain the engine at iddle without letting it stall. Finally when the can was about empty I let it stall and allow it to sit for about 15 minutes (Corvette forum recommends letting it overnite).
Then I started the engine and what a mess? My whole street looked like smoke from fireworks, since I live in a rural area I drove the truck for about 15 miles until the white smoke stoped, then I went home and changed the oil and filter. Oil had only 1500 miles and it looked like it had never been changed.
I put the other can in the gas tank.
What a difference? I could not feel that the engine running unless I looked at the tachometer, went on a camping trip later on Saturday after this service and I could not believe the power, responsiness and smoothness of the engine. I still need to figure out if the MPH improved.
I recommend this to anyone wanted to do a good engine clean up.
 
You added a full can? The directions say 1/3can.
I done the 1/3 can two time in a couple weeks and my oil was not dirty.
Where is it said to change the oil after use?

I wounder how SeaFoam does compaired to paying a shop to decarbon via a high $$$ machine?
 
I had heard the water thing a long time ago from some geezer (and that is now me...). The old coots used to do a bit of it all the time. But I never had the nerve to toss any water into the carb or TB.

It does make sense--if you've ever used a wood burning stove, you know that the only way to get that carbon buildup off is to use water--all the solvent in the world won't budge it. Maybe I'll give it a little try. After all, Dan is using it as a matter of course with his MeOH/Water injection system.
 
Will the water method work on the 1FZ?
Many older motors had the intake and exhaust on the same side. The intake manifold would be very very hot and the water would steam.
The 1FZ has the exhaust manifold on the other side so the intake manifold is cooler and the water might not steam up.

I think the 1FZ might hydrolock more so than a motor that the intake is heated????
I would yield caution adding water to the 1FZ.
 
What is this yall' preach? I have never heard of putting water in the combustion side of an engine? :confused: :eek:
 
I used (a Coke bottle of water) to do it all the time back when I had an car with a carb, smoked a bit I never had and hydro lock or any issue can't really say I recall that much of a difference. BTW, I read somewhere that seafoam was just lin seed oil anyone else heard that one?
