best why to clean out your hole motor is ti rebuilt it :-D but i don't thinkyou want to do that. best think to do is take off the vavle covers and wee what the rocker arms look like.... if they are really bad looking then your goign to need to flush outt he oil best way to fo that is change the oil let the car run gor 15 mins change ti again let the car running like an hour or so and drive it around then change it ahain pop off the vavle covers and see if its any cleaner if you have crap stuck in the oil hole where the oil dripped down into the pan then your going to have to take off the intake and clean then so you don't push that crap intot he lifter vallly (use 10w30 to clean out the oil... i have been useing that on my motor since the day it was built)

now as for you saying " but I do want to remove the things that are fairly easy to, like the oil pan, head covers and stuff like that to clean. " good luck tryign to remove the oil pan in our cars witht he motor still in the car LoL

as for the fuel system first think is a fuel filter and you said "I want to remove all carbon deposits and anything that I don't want in there. " best way to do that (i do this ever time i start to rebuilt a motor) take a spray bottle and sray water into the intake on thecar (not the cold air into but right where the TBI system is on your car... doign this is just like stem cleaning and it would remove EVERY thing on your pistons and vavle. (i learned this when i had a blone head gasket on my mom's car 3 years ago i saw where one piston was clean as hell and looked brand new.. i asked around and said that was the cly where the anti-frezze was burnign and that its normal... thats where i got the idea. fuel injecter cleanner is the best thing to do for the injectors

The way to clean out the engine is to change the oil, but replace one qt of oil with transmission fluid. Drive it for ~500 miles then change it again without the transmission fluid. Trans fluid will clean about anything. The stuff is dangerous. (Just kidding about the dangerous part )

Mike's right about spraying water into the engine.

What you do is get a spray bottle (new would be best, that way you know nothing else could contaminate the water like soap, window cleaner, hairspray, etc.).

Take off the aircleaner. Start the car. Use your hand to bring the RPMs up a little. Lightly mist the water into the engine as it's running.

Stop spraying as soon as the engine acts like it's going to stall. That means you're spraying too much. Plus excess water can harm the engine.

 

I've got a couple of newb questions to add..

I heard that you could also add alcohol (isopropyl?) to the water bottle (50/50 ratio). Can anyone comment on that one? How often would you want to use the spray bottle "technique"? Would you do it every year?

Another question: I've noticed on some cars, that the dipstick would sometimes have some black material (varnish?) stuck to it that can easily be wiped off.. what causes that, and what's the best way to get rid of it?

 

I can't say I've ever heard of the alcohol. I'd be afraid to do it myself. Alcohol has a way of drying things out. It's good for removing oil (like on zits ).

The black on the dipstick could be carbon. If an engine has a small amount of blow-by from the rings being worn, the fuel gets into the oil and does that. Or it could be just from not changing the oil often enough.

 

people do that so the motor won't stall out when spraying the water ( it burns thats why) but it takes longer for it to clean out. best way to do it is to use 100$ STILL water but tap water will work just fine

 

On the my TPI car, would I just spray the water into the TB? Wouldn't I have to have the car at full throttle though in order for the water to get past the blades? And is it important that the engine is hot before doing this?

You would just move the throttle linkage.

 

yep

You’ll know when you’re spraying too much water because the engine will want to die. That’s why I told you to hold the throttle open a little to keep the RPMs up. If you spray water in there while the engine is at idle, it probably will die.

Water has this really cool ability to get stuff wet. When dirt gets wet, it’s easier to remove. You use water to wash your car don’t you?

The carbon deposits get wet, and because they’re hot, they cause the water to get hot, and then the water becomes steam. Too much water and the engine won’t be able to get rid of it. It’ll spit drops of water out the tailpipes and the engine will start to die. This is MUCH less likely to happen if you spray the water into a mist, similar to how fuel injectors do.
