If heared of this before and also at Maximadriver.com, and was wondering if any fello 3rd geners performed this cleaning of the engine insides on their 3rd gen. Steam clean it is, and if its worth letting deionized water go into one of the vacuum hoses to steam clean the engine out. Its been said that u get smoother and better power out of the engine. Let me know if its been done to any of your 3rd gen maximas...thanxxx 
I guess no one has done it.

Good Question,About 1 week ago I used 4 cans of gunk engine cleaner on my car.And for some reason lately my car has felt very strong.NO I am not just saying this it seems to pull harder.All I did was cover up my alarm horn and my pop charger with plastic grocery bags and went to town.My car smelled like gunk for about 3 days.But it is clean as hell and like I said it does pull harder "NO JOKE".I did this because I had my oil leak fixed and really wanted to get all the oil off.Do it you have nothing to lose.

That sounds smelly 
maybe Ill try that too (on the outsides) , but the method I was talking about actually consist of cleaning the inner parts of the engine. Actually running water through the V/hose n out the exhaust. Damn if gunk gained u power on just cleaning the engine outsides, I wonder what gains Ill get cleaning the inner parts of the engine.. (Ill stick to steamed water though) haha. Thanks

I've heard of problems with o2 sensors dying a short while after doing this. A better way to do this is get a top end/carbon remover product designed to do this. Mazda, GM and NAPA sell these cleaners. Proceedures that worked on cars 30 years ago may not be the best thing on modern, emmision controlled cars. I would also do a top end clean right before an oil change, since some crud can get flushed passed the rings during cleaning.

Another one that's been mentioned is using transmission fluid instead of water.
the tranny fluid has all kinds of detergents and other neato stuff like that that will break loose and dissolve the crap on the inside of the engine.
probably wouldn't hurt to run some water through it afterwards- and remove the O2 sensor for the entire cleaning process. it can't go bad if it's not in the car.

If you've got chunks inside your engine, the least of your problems will be what fluid to clean it with.
the stuff that builds up on the inside of the engine are varnishes and sticky gunk fron the gasoline, oil, and in the air.. it forms a black, greasy mess on the inside of the manifolds. After a while, it can cause slower throttle response and generally poor running.
for a pic of the goo, look here:

I was thinking about the crank case. Steam (water) and oil? There usually sludge in the bottom of the crankcase and bit all over. Mystery oil is great for removing it, BUT the SEALS MAY DIE and engine will have to be rebuilt. If it were my car, I would use high detergent napathallinic based oil (most motor oils are napathallinic based) and change every 2000 mile or 1 to 2 months with good highway miles to remove the sludge and then change to a paraffinic or synthetic based oil.
As for possible manifold varnish, before trying something drastic, use a couple tanks on high detergent gas (e.g., Texaco super.) -- That's what the local dealer recommended and it worked on my 93 GXE.
If the engine apart, each separated piece can treated with a degreaser, then varnish solvent, dry and light oil right away or rusting will occur on iron parts.
IMHO
Do at your own risk.

The pics in my post above were after 40k miles of ONLY 93 octane Texaco gasoline. they're still nasty.
of course, since I had it apart (for cleaning and polishing), I cleaned he inside with parts cleaner and a wire brush.. made a pretty noticeable difference in the throttle response.

Fuel doesn't touch the inside of the intake manifold until you get to the injectors. Everything from the TB to the injectors only sees air and crud from the EGR & PCV. It doesn't matter what gas you use. That's why you have to use a cleaner from the TB, or take the intake apart,

Just wait till you see Maxima 2.0.I'm not going to post any pics of it until I get completely finished.. (of course, I'll take pics along the way but still)...
let's just say you will cream your pants when you see what I'm doing with the system.
