So adding this to my tank will clean the injectors? In the oil will clean the crank case? What does it clean if you use the vacuum line at the rear of the engine? Manifold maybe?

Yes. Yes, crankcase and anywhere the oil gets to (including the upper valve train). Try to put it into a vacuum line that will allow the seafoam to be evenly distributed like a vacuum line that is in the middle of the manifold (like the PCV valve line). And it should clean the inside of the intake manifold, intake ports, and intake valves. You should be good.

It only cleans the injectors if you put it in the gas tank. If you suck it through vacuum line then it cleans the carbon buildup in the intake manifold.

I wish someone else on here was in Alaska...I need someone to show me what the hell the vac line is....

I can, however, find my own gas tank.

Hmm.

If it ain't broke, don't fix it, right?

I think I'll hold off for now. The last thing I need is car problems.
