i dont have a pic but i can tell you how bad it was, i had about a 1/4" build up on all surfaces leading all the way to the heads and down in the heads, which btw the b-12 does not clean very well, no one yell at me that it does it may just be my car, but i removed alot of carbon build up like a day after a cleaning



Yes, it was a struggle even with the B12. Lots of scrubbing and grinding. Cleaning the heads was for only the faint of heat......



Whoops, shoulda read that. I still believe the B12 is great, but only if you can afford to get enough to dip the whole manifolds into. I spent the whole day since 3 oclock until now (10:30ish) trying to clean my manifolds and heads for rebuild tomorrow. Im still wondering how everybody cleaned the UIM without getting a big container to dip into.




this sounds wierd but it works, but can only reach part of the way into the manifold, but i went to walmart and bought what looked like a baby bottle cleaner, it was a stiff brush that kinda curled at the end, it worked really well although i went through 4 of them because of how bad the heads were, use those and something like paint thinner, or mineral spirts, and you should be able to clean it out pretty good, also i poured the paint thinner right into the UIM and let it sit a little bit, it is cheaper the B12 and works about the same



Thanks for the info, too bad I just ran to pep boys and bought 4 more cans of B12. Slaving over the heads and LIM with q-tips and shop towels was a [censored], but i got it done. I still got finishing touches and ill take pictures and post.
