Do in-line engine cleaners work?

[get_nick]

I have a ton of carbon buildup in my EGR valve and i'm wondering if the head is a mess as well. Car has 200,000 miles on it.

Do engine cleaners work if you directly pipe them into the brake booster line? (seafoam/wynns etc)

@civicious. I recall Wil saying any sort of additive is usually garbage.

i couldn't remember if he was referring to seafoam specifically or all of them. i'll have to check his thread. now that you mention it, i remember him saying he flushes the oil a couple of times and runs it. thanks for the reminder.

Check his RSX thread, he goes into a lot of detail.

For your particular case, your only option is going to be to remove the EGR valve and clean it. With 200k, it probably isn't a bad idea to pull the head and send it to a machine shop to be cleaned, honestly. The flush I referred to in my RSX thread was in the crankcase, to clean up sludge deposits and whatnot - but that wouldn't do anything for buildup in the head/intake/exhaust. You're pretty much SOL on those fronts.

Sucking solvent in through a vacuum hose will do nothing for you. You can For the most part, additives are garbage.

Thanks for the input. I pulled out the EGR and cleaned it up pretty well. I wont waste my time with the crank cleaning.
