I would like to clean the carbon build up in my engine and would like to know if this procedure is right. Take a gallon jug of distilled water, connect a vacuum line from the extra nipple on the UIM to the jug. Now do I have to keep this line pinched a bit or can I just let the engine vacuum take the water freely while I rev the engine to about 4k to keep it from stalling. Another other advice would be greatly appreciated.

Which are this two nipples as mentioned in Rotary Resurection. Can someone post a pic. "Some engines (fd’s and s5 na’s for example) have 2 separate nipples that can be teed together externally (vacuum hose and tee) to evenly feed both rotors."

just do one gallon per rotor. one rotor at a time.

I did this an had a 5psi jump in my compression. still holding strong.

I believe these are the 2 nipples on the side of the UIM before it connects to the LIM. One is used as a boost source for your gauge.

id go outside and take a pic, but its like -30 here. BURR.

yea, did that stay? like the jump in compression? or did it taper off and go back to the previous compression #'s?

BC-FD3S

iTrader: (2)

nope, it's still the same. hasn't dropped yet.

wow that's impressive. How many KM on your build?

so I tee the two nipples on the UIM? There's no problem running the car without the blowoff valve connected and revving up to 4k.

no problem

rev the **** out of the car, having a buddy there to help you is always nice too

or you can rev it VIA the throttle body like i did. wear gloves though.

I'd recommend revving the motor to about 3000-3500 rpm.

You might also keep an eye on your downpipe and make sure it's not getting anything too hot.

Why would it? just curious.

Water into the combustion chamber should cool down the EGT's. And its not that long of a process either.

I just wanted to know how often you guys "steam clean" your motors. I plan on doing that this weekend and I just wanted to know the mileage intervals on cleaning it.

Great Info

Thanks!

I use Seafoam http://www.seafoamsales.com/motorTuneUpConsumer.htm then follow it up with water. I do it around once a year.

Now that I think about it my motor is about due for some steam cleaning.

Years ago when I was part-owner of Gotham we had a customer deployed to Iraq and we were storing his FD. All the months of starting his car to move it outside and shut it down caused a side seal to stick (90k original motor) and the steam cleaning caused the problem to clear up

Hey Boosted94:

When you´ll do it,

why don´t you take some pictures and make a video.

Then you could make a little easy to understand how-to for everyone!

i have done this for years on my own and customers cars but only recently did i relize that your shaving some life off your housings by washing down the oil coating and metal on metal is in more contact. anless you run premix i probably would not recommend. i steamed a block before a rebuild and eveything was bone dry no oil or anything when i tore it down so just keep it in mind

shifterkartracer

Would you then suggest running a premix, drive around for miles, then steamclean?

or run a premix after?

Thanks!
