always at mazda and a B6 head which was mine for ~40k and seafoamed
twice. I thought id post up with actual pictures about what the seafoam
does to the intake and exhaust valves. It is most interesting.
(The heads are both within 10% kilometers)

The most surprising is the intake valves:

You can see the intakes are super clean in comparison to the BP valves which
have a noticeable gunk build up on them. All the intake valves ridges can be
seen, the results are very uniform.

Now onto the exhaust valves:

Not as much difference here but a difference in cleanliness is noticeable. Im
going to attribute this to the fact that the 94 B6 has EGR and the BP does
not. EGR is bad.
