Hi. I have an 05 yd 6.0 and I want to seafoam the intake. I have the hydra-brake boost on this truck so not sure which hose I can use to distribute the seafoam into the intake evenly. Anyone have a diagram or pic with the hose identified that I need to use to pour the seafoam??

 

Thanks!

should be able to pull the hose right off the brake boost. start the truck and pull the hose, if there is suction there you should be all set.

The brake booster is a hydroboost set-up. Meaning that it gets it's vacuum from the power steering pump and not the engine.

Yep, you are correct. It does not get the vacuum from the engine. So, any other ideas on how I can get it into the intake evenly distributed?

I found it. Thanks for your help and guidance - really appreciate it!

 

On the rear of the driver side valve cover there should be a vacuum hose connected to a PCV that sits in the valve cover. You could use that.

seafoam works great, how often are you using it on your truck? I used it on my 4.3L and got excellent gas mileage and it seemed to keep everything clean...

 

i put it in the oil 100 miles b4 an oil change

i put it in the gas tank a few times a year

i put it in the intake via vacuum

 

(haven't done it on this truck yet, i now have 6,000 miles is it time?)

      This is a really late reply but I just found this thread. They won't sell the hinges. I've gone 7 rounds with them. Their solution is to buy a new cover. I'm about to buy a new cover and it won't be a Bakflip. It also won't be from realtruck.com.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      4 low is really nice on steep boat ramps.

      Gas Prices

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.
