I let it sit for 7-8 min and used about 1/2 the can.
Leading evidence: 'Use about 1/2 the can' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Clean by way of direct manifold vacuum line' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Use techron and never saw this kind of improvement

I have used Techron and never saw this kind of improvement

Also I want to clean by way of direct manifold vacuum line that will feed ALL CYLINDERS or other possible source ie.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hoping to get some cleaning done today. I did a search and not one 996 guy has posted about it. The 993,944 and others are all doing it. Some have seen some good improvements.
Has anyboby used this Seafoam in the oil. How long should I run with it in the oil. Some say 500 miles before oil change. There are no direction on the can, and I don't want to buy a new engine.
Also I want to clean by way of direct manifold vacuum line that will feed ALL CYLINDERS or other possible source ie. brake booster line. Does anyone have pictures of which line I should use.
Any advise would be helpfull
just never seen a m96 motor with sludge ( excecpt an intermix car or 7 ) or any other debris,
Lil techron to clean the valves every 5-6 tanks and your good to go
I've tried seafoam and several other similar products on a 964 horizontally-opposed 3.6L and I checked my intake & exhaust valves and pistons and there was no visible difference to any component in the engine. The only cool thing about seafoam was the F1 worthy smoke show. Otherwise it was a total waste of money.
I have used bunches of Seafoam in a variety of engines as a fuel additiive. Good product, cleans up carbon deposits, and makes them run smoother. I have never dumped any in the 996 though. YMMV.
Just did the cleaning through the vacuum line.
I let it sit for 7-8 min and used about 1/2 the can. The car just sucked it right up.
Not that much smoke, I have video I'll post later. I guess it's because I rev the **** out of her every day.
There is 1 improvement that I saw.
1. Engine running just a little smother. Back fat jiggle
and RPM's confirm this.
I have used Techron and never saw this kind of improvement
I'll have to see if fuel mileage improves after I finish the full tank of gas I have.
In the end I�m happy with the initial results
Any fluid left to sit in a horizontally opposed engine will most likely leak right out an open exhaust valve. It might work on a V-style cylinder head/piston but not here.
You should let the tranny fluid sit overnight for best results. It vaporizes in the intake and will sit and soften any carbon on componants it gets to. The longer your car smokes the next day, the more crap it has cleaned.
Oh God, someone is going to hydraulic lock there motors over some carbon build up.
I admit, I have used tranny fluid and good ol' water while revving the snot out of the motor once the engine was really hot, I only noticed a difference around the intake side of the combustion chambers and the middles of the pistons once I tore my engine down, it didnt get everything. This was not a Porsche motor though.
No worries, no hydraulic lock going on here.
So if you did it with other motors whats the big deal? Because it says PORSCHE???
Ya, maybe only some build-up but it does run better. I forgot to mention that my idle oil pressure went down 1-2 ticks. From 1.8 to 1.6 Not really sure why that is???
All in all like I said before, the car runs better
Check out some of the Jeep forums, all the 17 and 18 year old kids are using this trying to revitalize their 20 year old Jeep Cherokees. Everyone of them claim miraculous results such as better gas mileage, easier starting, less oil consumption, quieter lifters and overall quieter motor. Some have reported noticeable increase in power, motor no longer slowly loses idle speed and dies, no more fouled spark plugs, and I think one guy even reported seeing a hologram type image of the Virgin Mary hovering above his motor when he lifted the hood. I guess what ever works.
I guess what I'm trying to say is
Have you ever blown up a motor by this method or caused internal damage? You said you've torn down an engine after doing such a thing. I have seen plenty of bmw,moded stangs,and rice buners use this stuff. It's all over you tube and forums; kind of funny watching some of them.
If you know something that will cause damage to my car using this method please let me know.
If you look over at the 993,964,944 boards, you'll see they use these methods on Porsche engines. I don't think were drinking the coolaid
(seafoam) and seeing Elvis, or even the Virgin Mary if we use this method to attempt to gain better engine performance ie gas mileage, idle smoothness,throttle response,ect
I'll post back when the engine blows and you'll all can have a good laugh at me
I know the guys on my Land Rover forum use this stuff all the time - in the oil and in the intake as well.
Seems to be a cure for just about any ill.
I'm thinking of using it to clean my espresso machine - it seems to clean just about everything else!
No, no, I didnt say that Seafoam will do damage, I was talking about 1999Porsche911 talking about using tranny fluid and letting it sit in the cylinders. It was more of a joke because I could see people putting a quart of tranny fluid into the intake, it all running down to one cylinder and trying to crank the motor and then destroying it.
Using ATF as I described has been part of engine maintenance for more than 50 years and using it does not put the engine at risk. Does spraying carb cleaner in the intake blow the engine? Does pouring Miracle Oil in the intake blow the engine?
When sucked into the engine the ATF hit all parts of the intake track and does not go to just one cylinder. Does a great job of softening carbon as it vaporizes and clings to everything.
In my prior post I mentioned I have done the same with ATF and water, it just came off to me when you said let it sit overnight, that you dumped fluid in an engine when it is off and the next day cranked it.
Wanted to post one more improvement that I have...
MPG is over 5% increase over the last 10 tank fills.
Went from 18.3 to 19.5 MPG average per tank.
I drive about 10000 miles a year so thats about $85 savings on fuel a year
Just doing my part to clean up the environment
Anyone ever heard of Motorvac? I had this done when I first bought my car. I'd never heard of it before, but my tuner guy suggested it to see if it would help the lumpy idle the engine had. Seemed to.
An article about it:
http://www.theautochannel.com/mania/.../motorvac.html
I have used literally cases of it. Used a bunch on 2 stroke outboards - works great. I also used some in my old P/U, my BMW 535, and in a couple chevy small blocks I had in a marine application (Bertram 28 FBC). Down the top works better on auto applications that simply mixing with the fuel.
Never put it in my oil though.
Have not used it on the 996 yet, but I would not hesitate to use it. Speaking of which, now that I am at 79K, might be time.
