Seafoam into a 3.2 intake?

[kach22i]

The drawing really helps - cool.

Just put it in my wifes 91 V6 Landcruiser before she went on a 3 hr drive to Seattle.
The car had been spitting and stumbling for years with poorer mileage with nobody able to get it right; injection vacuums, filters, tuning , wires, Super shell or Chevron super always.

Oil change, diff change, whole can in the gas tank and a missle of Lucas Oil treatment and she says the car has never run better and she is getting 3-5 mpg better. She has hated driving that car daily for ten years so this is really something.

Good thread.

So which vacuum line would be used on a 3.0?

I know you are heard several stories, but all I did was to purchase sea foam at Wal-Mart, put it into a half tank of fuel and it cleared my injectors. Period!

Where do you live? Nearly all auto parts stores carry it.

Just read through this and then "seafoamed" a 3.2 Carrera.

Wanted to share my experience and possibly the easiest method for using seafoam into your vacuum line.

The absolute easiest way IMO is thru the top hose that connects to the fuel pressure regulator!

The fuel pressure regulator is located on the left side of the engine towards the cabin. It will be a golden zinc color.

You will see a rubber hose on top of the regulator (DO NOT PULL THIS HOSE OFF).

Instead, pull the smaller rigid hose (connects to throttle body) from this larger rubber hose that connects to the regulator.

Then slide over a small diameter (6mm ?) rubber hose ( 18 - 24" long) over the smaller rigid hose. You will use this hose to pull in the seafoam.

BTW....Your car should still run great with this hose disconnected, so you can have your seafoam hose all setup and ready for the seafoam, then drive to your local Costco or other large parking lot if you do not wish to smoke your neighbors.

Pour the seafoam into a plastic container (1/2 the can and you can use a small water bottle for this).

Get the engine up to running temp.

Hold the bottle with one hand and keep the other hand on the throttle to keep it from stalling.

Take a little seafoam at a time and when the bottle is empty let the engine stop and wait 15 minutes before you start it again.

Thats it!

The engine runs better and is more responsive now after the seafoam.

Tried the seafoam up the fuel pressure regulator vacuum tube, wow like a smoke screen out of garage. 5miles after on a run it’s cleared. Have some in tank also. I have an endoscope view in through plug hole from a week back during fuel line change. Will post an after shot later this week.

As promised here’s the endoscopic view afterwards it was a reasonable improvement even though it may not look like it, it’s 88k and never been rebuilt. . Had its first general overhaul of fuel lines intake gaskets, oil thermostat gasket amongst many other little bits including rodent wire damage repair. Fab speed muffler this next week.

Take a lesson from this YouTube tester.

https://www.youtube.com/watch?v=2ySSEzqEa_k

While his testing methodology was sound, his main mistake was introducing water in a liquid form. This process requires small water drops (a water mist) to be most effective. Collecting as much water as he did in the crankcase (and at idling speeds) would have shortened the life of any engine of value.



Has everyone driven in the rain? Of course. Same thing.

I've only used Seafoam on small engines, but when I do, I empty the tank of gas and put in a couple of ounces of Seafoam. I then start the engine until it's basically running on Seafoam, then stop it and let is sit for a few hours. Then, I empty the Seafoam from the tank and fill it with gas. I start it up and when the smoke clear, the engine runs like a top.

I'm not sure I'd be brave enough to do this in my 911 engine though....

I worked in a service station as a teenager in the late '50s. We used to do a water cleaning of engines. We'd park the car with the back end sticking just outside a station bay door. With the hood open and the air cleaner removed, we'd trickle water (sometimes out of a Coke bottle) into the carburetor. A huge plume of blackish gray smoke would come out of the exhaust. We'd pour enough for the engine to just start to stumble then let up. I don't know how much the owner charged for this & never got any feedback on whether the engines ran better or not. In those days, nobody would complain about large clouds of smoke billowing from a gas station.
