is there anyway to do a combustion chamber flush on these motors? what i mean is i know you can go through the fuel rail or poor in tank contents, i used to like going through the brake booster line to the intake manifold with b12 or seafoam but since the blower is on top with teflon coating on the blades is that safe or is there another way of doing it on these motors? if not no biggie just a thought i was trying to figure out.
