vatozone, kragen, checker, shucks, pepboys, one walmart in vegas, napa, carquest, um...
that shit works great, i got a bucket of it right now. my friend used it and gave it to me when he was done.

Thank you, we've ben looking for that stuff to have at work and none of the older guys could remember the name or where to buy it.

I use subaru upper cylinder cleaner, it comes in a spray can and I just coat everything and let it sit for 15mins and the carbon turns to a liquid. And its free from work  O0 :noel:

i have used oven cleaner to clean heads and intake manis.  but only leave it on for a couple of minutes, it WILL eat through shit if left on too long, but it works great.
