Topic: cleaning an engine from the inside out??

[BLACKDOG]

I just did an engine swap, 3.0 for a 3.0, and the engine I have in my truck is running a little odd.  I know that the engine sat for a while after being pulled, and also that it was run for about 6 months with the hood off in placerville.  Is there a good way to clean any crap out of the engine that may have goten in there, like deposits and rust??  I have seen the enging cleaner additives, but I do not like additives, I was taought not to use them or rely on them by my Grandpa.  Is there a good way to do what I would like to do aside from tearing it apart and doing it by hand.  That is what I am doing to my other engine

seafoam, it's kinda sorta an additive - all I know is it did wonders for my old jeep engine.

Go buy a little spray bottle and get some methanol alcohol.

Mix the methanol with water, 50/50, and put it into the spray bottle.

When your engine has warmed up to operating temperature, turn it off. Then pull your air cleaner out, fire up the engine, and with it idling start spraying the mixture directly into your intake system. Yes I am being serious. Just to a couple sprays every few seconds or so. The engine will just sputter out if you spray in to much, you will not hydraulic your engine as long as its running so dont even worry about it.

Then with your other hand rev the engine up a bit, like 2000~3000rpm and hold it constant. Then increase the rate at which you are spraying the mixture into the intake.

Do this for as long as you want to and you get bored.

Once you stop, let the engine idle for about 30seconds longer after you have stopped spraying, and then turn it off. Let the engine sit for a while, like for an hour or so, so that it cools back down.

Then fire it back up and drive it around for a couple of days and then do this again.

Do it like 3 or 4 times and alot of the gunk will be cleaned out of your intake system.

ok, but I have a k&N air filter, and If I take the tubing off the throttel body, the engine wont start, and If I remember right, it dies if I pull it off after I have it running.  Or do you mean pull off the element? and leave the tubing attached to the Throttle body?

[BigMike]

No, no, you must leave your air box connected to the tb without any vacuum leaks.

Just pull the cone filter off and spray the mixture directly into the intake system.


To be honest I dont know how well this will clean it out at just an idle, or ~3000 rpm without a load, but after using the water/alchol injection in my SC engine for a couple of months, I pulled the intake apart for maintence and it was really really clean. Looked like it had been through the solvent tank.

You can also use eather but it stinks after it combusts. Really smells bad. The meth () is safe for your o2 sensor and cat, and everything else..
