I've done the seafoam method before through the brake vacuum line as many threads have stated, well this time in doing water because of what cruiser54 says(he knows his stuff lol) but I started thinking about the vacuum line, I realize that it is farther back on the engine where it connects to the manifold, so clearly water or seafoam will get to the back cylinders, but what about the front cylinders? Does the placement of the vacuum line determine where the liquids will go? I would like to use the throttle body since it is in the middle but I have heard bad things happen to the tps and iac from pouring water or seafoam down the throttle body. Am I exaggerating to much on the vacuum line or not?
