I was wondering if there was a way to clean the inside of the engine without taking it apart. I know i can get some fuel cleaner but is there anything else??

and no i am not going to try the ATF trick.

from my boy "DSSA":

"As far as using it in the engine (via vacuum line) this is old-school. Go to your local Mopar dealer and ask for "Mopar Combustion Chamber Cleaner". Same thing, gets rid of carbon like nobody's business.

I usually get two cans (aerosol), and follow the directions for one (use half can and keep car running, then apply enough to stall the car and blow the rest in). Then I usually pull the plugs and squirt the other can into the cylinders via the sparkplug holes, and let it sit overnight.

Before starting the car, place a towel over the sparkplug holes and crank the car over (with the plugs out of course) to expel the bulk of the cleaner from the cylinders (you'll be amazed at the amount of carbon that comes out with it). Then start the car and let it idle for about 10 minutes. Then drive the car *easily*.

A lot of people have said to go out and "hammer on the car", which is the exact opposite thing you should do immediately afterwards. Anything that removes carbon, is also going to remove oil from friction surfaces, and even on the best compression cars, some is going to get into the crankcase.

After you run the car lightly for about 5 minutes, change the oil, *then* if you want to go out and beat the hell out of the car to blow the remainder out of the exhaust, go for it.

One car I did this to (Galant VR4 w/ 153K+ on the clock) blew a headgasket about two days later at the track (was running high boost and crappy gas--my own stupidity). I pulled the head off to swap the gasket that night, and the pistons/valves were clean of carbon almost completely (regular *light* coating that's normal of course). Been using it ever since."

how about good ole ATF? i saw that on another thread...http://www.nissaninfiniticlub....39360

look @ nismo2887 link

but, then, u follow up w/ changing plugs, o2 sensor (maybe), n the oil change...

would it plug up the cat? then, I would plan to disconnect from the cat & just "blow" out the crap from the downpipe

RXP, also works well. Then all you need to do is change oil, it only cost 6dollars.
