I have a 03 s60 with awd turbo. Which vacuum line do I use to seafoam my car? On all my other vehicles I used the power brake booster vacuum hose. Do I do the same on a turbo vehicle?

 

I seafoamed my S60 yesterday and I used one of the two small vacuum lines pulled off the air filter box. Any vacuum line should be good.

use the line that plugs into to the brake booster, its big and easy to get to.

 

You want to use a small line. If the line it too big it's just going to suck the can in and burn it without getting much benefit. The smaller the line the longer the chemical will be getting sucked in and coating the valves and intake and dissolving deposits.

Seafoam now makes a special product just for injecting into the intake where you can do it ahead of the throttle plate and get the throttle body and plate too. It's a pressurized can with a "straw" that slips under the intake pipes joint pre-throttle body.

 

is this good for the car or will it wear out seals? also is this good if the pcv hasn't been serviced

 

Seafoam shouldn't do any damage to anything. There is the aerosol like above for spraying into the intake and then there is liquid for drizzling into the intake or pouring into the fuel tank or engine oil pan.

As for the engines PCV system you can drop a can of Seafoam into the crankcase and drive it till it's due for an LOF. It adds detergents and helps clean the inside and might do some good in cleaning out the PCV black box from the inside. You can also try an engine flush but make sure it's something you can drive on. Some it doesn't matter how long you leave them in, some are very thin and harsh and can only be added and idled for an amount of time and then need to be drained without driving on them.

The other thing you can do and I have on my turbo, is toss in a quart of transmission fluid. The transmission fluid is also just oil (roughly 10W) with a much higher amount of detergents. It's a good way to let the engine clean itself.

 

Does it harm the engine if dumped directly into the fuel? I bought a can due to the fact my car had been sitting for awhile and I wanted to add it incase any moisture had built up in the tank/lines.

 

Did you read the instructions ?? Go to their site and see how it's used.

If you were asking about using it for an "odd" application I'd answer that question but it's so basic, it's just foolish.

I'm here to help people and I'm sorry for taking it out on you but I get tired of people who don't do any work on their own part (simple net search), can't crack open the owners manual or even think a little. (And no, those don't all apply to you)
Again, sorry for being harsh just irritated buy another post just before this.

My personal opinion ... use "Heet" to remove moisture and "Lucas" fuel injector cleaner for cleaning. If it's just moisture, toss in the Heet and you're good to go. It's also MUCH cheaper. They each do their own job better than Seafoam. If you can dump Seafoam in the gas and oil it can't be the best for either. It is a good product, don't get me wrong it's just not the best (IMHO) for any one problem.

 

I personally read the can directions (one can treats 8-25 gallons of fuel). I read the directions. I was just wondering I anyone had a PERSONAL horror story with it.

 

After I put it in the tank my brothers friend commented that he knew a guy who threw it in his tank and it didn't help anything.
