Does anyone know for certain how much, if any of the EGR system and tubes, etc. will clean up when having a Motor Vac service done? I assume not much.

 

Motor Vac works well - No comparison to Seafoam..It's good for your EGR as well- It clears the EGR port in the TB.

 

what's motor vac, or should i just search...

 

The sales people that sold our shop the MotorVac system told us that seafoam was pretty much the same solvent that's used in the Motorvac system. I've never watched the procedure, but I know that it's hooked up to the fuel rails and gives a much more concentrated douche than dumping seafoam in the gas tank.
