Thanx for the reply and info. I was looking at it last weekend and didnt see any vacuum port, but then again I really wasn't looking all the hard, just gave it quick once over. Ill look again this weekend.

 

well u might not have a free port like in that picture so u mighr have to pull off a vac line thats already on there...pull a brake booster or the like.

just remember to clean any one you pull off nice n good to prevent sucking in any dirt/sand/debris that might be on the hose near the vac nipple.

 

This was a fun sticky to work! I cannot believe how much smoke came out, and how long it lasted! I intentionally did this in the evening so that I could drive around and not look so freaking obvious, as I am in a large city. lol

I must confess... This was so much fun that I did it a second time when I was due to change my oil. I put Seafoam in the crankcase, the gas tank, and did the induction cleaning along with the throttle.

The beast is more responsive than ever. This sticky led me to the spark plugs and magnecor wire upgrade recommendation. This site is creating a monster out here in Syracuse. lol

Thanks for taking the time to do this!

 

Does anyone know the size of the vacum line and where I could buy 1. Thanks

 

You can buy rubber or plastic tubing at any auto parts store, and at some home improvement stores. Size of hose determined by which fitting plan to use, measure hose (inside diamter, or ID) that you disconnect, or garb a little duct tape for home made adapter. Read instructions on the can. The WHOLE can is like treatment for three trucks. Extra can go in gas tank.

 

Hey
I read the whole thread and no one really addressed why this is a good thing to do to your truck. I understand that it will clean the internal parts that supply fuel and remove varnish that accumulates in these systems. The question I have is what symptoms point to needing to tackle this project? The other question I have is that someone said that after cleaning with Seafoam that their heads started leaking as it was "too clean." I assume that if a leak occurs after cleaning that you were headed for gasket replacement anyway, but I don't want to tempt fate. Thanks in advance for the advice, as always, you guys are right on!
Cheers,

If you do the induction type cleaning treatment, the seafoam liquid gets pulled along the air channels, to the back of the intake valves, and helps clean out oil/varnish/carbon buildup that can cause the valves not to seat fully, or just help keep the level of buildup below the threshold. i do it once every year or so, or on any time i get a new vehicle. the tons of smoke etc. is often misconstrude to be the actual crap in the motor burning off, thus it looks like its doing a great job cleaning things up. in actuality, the seafoam itself is just creating a lot of smoke as it is burned off in the combustion as it gets sucked into each cylinder and smokes off. you would get the same effect by induction cleaning with baby oil, kerosene, gas, diesel, motoroil, hell just about any patrolium product lol... ever see an oil/tire fire? lotsa smoke. how much of it is from the removed buildup, id like to find out. i would be interested to see one day if anyone has any pulled intake/exhuast valves and submerging them in a bath of seafoam to see how much buildup it actually removes, and if its suberficial of it actually flakes/peals off like aircraft remover on spraypaint lol. i know it takes some serious physical polishing to clean of the stuff... i woudl guess that the majority of the seat of pants feel of imporvement comes more from the cleaning of the spark plug buildup then the intake channels and valves, i doubt youd notice anything on a truck with clean plugs to begin with.

Thanks for the reply and the explanation. I just had my plugs and wires done as well as my valve gaskets so I think I'll skip this one! But thanks for explaining to me how it works and why it is beneficial! Loving our first Disco so far, 1000 miles into ownership.
Cheers,

I did the induction cleaning after replacing the plugs and wires. After finishing, I had the ses light on, throwing codes p0301 and p0308, misfire on 1 and 8. Some combination of the seafoam and crud which was knocked loose had fouled the plugs. A shot of brake cleaner and some compressed air on the electrodes seems to have solved the problem (I hope)

 

proof seafoam works maybe?
