Is it okay to use an engine cleaner on my Evo 8? (As in pouring engine cleaner liquid into the oil tank and letting it run to clean out the engine).

If so does anyone recommend a brand?

 

Personally i use my power washer and simple green. just cover the MAF sensor and do not directly spray over the Coilpacks/Spark Plugs and Fuse Box.

Never had a problem.

Read that wrong... never used seafoam but have in my old car and didnt notice a difference.

 

I would recommend SeaFoam.


Pour it into your gas tank and follow the instructions on how to suck it in via a vacuum line...

I have only poured it into my gas tank. You'll need to change your oil if you try the vacuum line method as well so make sure you have an oil filter, drain plug washer and your preferred oil handy so you can change it shortly afterwards.

He's talking about actual engine cleaner, not engine BAY cleaner. Simple green is my method too!

 

Been hearing a lot of positives about CERMA as well. I have no exp with it nor will I ever use it but it is becoming quite popular with the GDI guys

They use the engine treatment then the nano treatment found here. CERMA has their own oil as well

Old school method.... Add 1 qt. of dextron transmission fluid in you oil the day before you change your oil. Put a few miles on and change oil. Transmission fluid has tons of detergents it works great.

 

^^^^ I have used seafoam with great success. In Gas Tank, Oil, And Vacuum lines.

 

Thanks! I'll give SeaFoam a try

 

If you do the vacuum line method don't be freaked out by the huge cloud of white smoke that will form up out of your exhaust, this is normal. That's all the carbon and gunk blowing out of your internals out through the exhaust. Also, don't stick your vacuum line all the way down in the seafoam as this will cause your car to stall out and shut off. Here's how I do it:

1. Get a empty plastic water bottle (the normal size, 12oz I think?) and cut it in half. Fill up the bottom half with the SeaFoam
2. Once you've chosen your vacuum line put the bottle half up to the vacuum line and let the line just barely touch the top of the liquid and let it suck in a little at a time, as in suck some in, pull line away for a second, suck some more in, pull away, and repeat until the liquid is gone. Your RPMs will drop each time, this is normal
3. Once complete, plug your vacuum line back in and you're good to go. As stated by others, change your oil that day or the next. I used to get 2 bottles each time and throw one in the gas tank, half in the crank case, and half through a vacuum line and then change the oil the day after once the seafoam had worked through the crankcase and fuel system.

Sorry if I'm insulting your intelligence but since you've not used seafoam before I figured these tips would be handy.

 

^ Good tips

cant you add the sea foam directly into the engine through the oil input?

 

this helps alot if your engine has sludge build up it will break it down and leave the engine like new

 

Easiest way I did it, I bought the small orange sized funnel from Walmart, using the orange funnel I poured 1/3 in the gas tank, and then poured the other 1/3 in the oil cap. I then stuck the funnel inside the Brake booster vaccum line because it is small enough to be able to fit inside, and then I just simply slowly poured a few drops of seafoam inside the funnel using the seafoam can, no waterbottle no cutting or anything extra. Hope this helps!
