Hey guys,

As my car is putting on miles, I am thinking about doing the SeaFoam treatment through one of the VAC lines. I used to do this every few oil changes on my GTI, but I have never tried it on the G35. Can someone please show me what vacuum line to use in order to suck the SeaFoam in. The car has about 72k miles, and I think that a SeaFoam treatment, tranny/diff. fluid change, new spark plugs, a throttle body cleaning, and Gordgee's grounding wires might really wake it up.

I bought the car from a relative at about 65/66k, and it was always driven sedately, but the previous owner regularly put in 87 or 89 gas and mineral oil. I think the engine itself is okay becasue many of those miles were on the highway, and the previous owner truly never took it above 2-3k in daily driving. Since I've gotten it, it only runs on 93 with Amsoil synthetic. It's quick enough to pull a stock 300c that runs 14.5@96.5 by about two car lengths.

Thanks for the help, and sorry for the banter.

 

I used the vac line going to the brake booster.

 

Gotcha, and where is the line in the engine?

Can I find it listed on the diagram by the front grille?

 

at the master cylinder. it's a thick rubber hose maybe 1/2"-5/8" OD. it's coming from the intake manifold to the brake booster. In the pic its the hose right above the brake fluid reservoir.

 

That's exactly what I was looking for. Thanks for the help!
