Hello all,

I've got a 960 '93 with the B6304 Engine. I've got a stuck valve and looking to try 'seafoam' to clean it up a bit before revving it up (as someone here suggested the "Italian tune up").

Seafoam instructions read: "With engine warm, slowly pour 1/3 to 1/2 pint through carburetor or throttle body throat. (If vehicle is port injected slowly pour SEA FOAM through direct manifold vacuum line that will feed all cylinders, possible sources are P.C.V. valve or brake booster line.) This will pull SEA FOAM down on top of the pistons and to the back of the intake valves to dissolve carbon. Turn ignition off. Restart engine after 5 minutes. If severe carbon build up is apparent, use more Sea Foam as previously directed. Make sure exhaust is well ventilated when using"

Which vacuum line do I pull and stick into the bottle? I'm new to these newer engines, so where it is located would help a lot.

Thanks!
