So we have all ready about Seafoam. Some love it, some hate it. In the thread below there is information on using a Mopar Combustion Chamber Cleaner on the LS1/LS6. I have done so on my wife's DD 02 Z28. I was planning on doing this to the GXP and was trying to figure out what port on the intake made the most sense. I don't see a similarly located port. Has anyone done anything similar or have any experience with this on the LS4?

i just use the rear pcv line and attach a 3/8ths fuel hose to it, and let engiine suck the seafoam in little by little

Do you have a pic of the line you used? I have not done this yet but cant the line from the brake booster be used?

I used the brake booster line and it worked fine. The car will bog a bit if you don't have someone to keep revs steady while you pour the seafoam, but it works.

Thanks. I did it on my daughters GTP using the brake booster hose and it worked fine as well. Just checking.

The brake booster line works with Seafoam generally, but I am concerned that I need to get it as close to the throttle body as possibly so it gets to the back cylinders.

Is doing a top engine clean with the mccc stuff considered a maintenance keep it clean thing to do or is it done to help fix eliminate a current problem inside ones engine?

Also wondering this myself.... Do you use the hose that goes to the brake booster or do you unplug the hose that goes into the air intake tube before the throttle body and spray it directly into the intake tube?

I'm a visual person and I need pics to actually be able to be sure lol
