Is it really necessary? I just replaced the plugs and I don't want to do them again.

I need to get the chamber clean for the winter.
 
shouldnt have to. i usually do a seafoam type treatment before i do the plugs.

i was at a training class for my work (major nationwide auto maintianence company) and volunteered my car for the fuel system cleaning. it was the system from Run-Rite. my car ran alright on the drive home from Los Angeles to Santa Barbara, but the next day it ran really bad. i pulled the plugs and all the electrodes were red, some had grey deposits. these plugs were about 5K miles old. Autolite 764 coppers. i had put them in a couple months before when i took it to Buttonwillow Raceway.
 
just use a quart of water injected by same technique....leaves the plugs spotless....search forum
water injection made the British Merlin/Griffin aircraft v12's the top fighter aircraft engines of WW2....powered everything from the Spitfires, the Mosquito bomber to even the US made Mustang....perfectly clean engines ran for hundreds of hours.....Pratt & Whitney radials had to be torn down and deposits cleaned every 25>50 hours or they fell out of the sky

You can use water yes. Distilled water, through the brake booster line to intake, it virtually steam cleans and balsts everything in thier. As for the plugs, i use mopar combustion chamber cleaner once a year, on my 1995 neon, prior to changing plugs. Ive read form others, who have used seafoam, its realy jsut a mild detergent, in my opinion, but all recommended changing plugs after combustion chamber cleaning, just in case. Regular coppers go for just over a dollar anyways.
 
Yea, I am the guy that posted the water combustion chamber cleaning a year or two ago.

I might try this again to clear out some crud.
 
So do you just jam the brake booster hose into a container of water or let it sip up the water a little bit at a time?
 
It may work better to put the water in a shallow bowl and SLOWLY suck it up. I wouldn't just jam it in a container as you risk hydrolock.
 
As you may have seen, I recently made a big thread about my Seafoam cleaning. I too was worried about plug fouling, but I never changed the plugs, and the car continues to run awesome after the treatment. I think you'll have no worries not changing them.
 
You allow the hose to sip up some water froma cup or bowl.

use the PCV valve line, not the brake booster.
 
I would try the PCV but I can not get at it. It is packed in the back. So the BB is way easier.

Oh, for the record I seafoamed 4 cars and the plugs where fine.
 
Excellent.
