Just got back from another road trip down south where I couldn't find any doggone hi octane fuel so I decided it's time to clean out the engine a bit.

I used to work with a buddy at a used car lot as his mechanic/salesperson and in doing this I learned a lot from other dealers about minor tuning, cleaning out engines and prepping cars for sale (and more than I ever wanted to know about window regulators). I found that using a bottle of seafoam injected into the older cars intakes was really good at clearing out the built up garbage inside.

It does put on a bit of a smoke show as mentioned in another seafoam thread but it really does work wonders on neglected vehicles. Mine has been babied pretty much of its 140K miles with mobil 1 and the best fuel I can find but since I was going to seafoam my sweeties minivan I went ahead and did the Marauder too.

I used a drip bottle system from a company called "full throttle" but you can make one from parts from a hardware store. The key parts are an adjustable ball valve and a tee that allows fresh air to mix with the seafoam before it's sucked into the upper intake.

I had noticed a bit of engine knocking at low rpm's which seemed to be worse after the roadtrip and now that it's been seafoamed, she purrs like a kitten at low rpm's and roars like usual when you get on it.

I have 4 pictures in my gallery of the drip bottle, ball valve and the air injection tee (that I will add to this when I figure it out again). I also have some video clips of the process as well as the smoke show if anyone knows how to post them.

Why use the "drip system"? Just follow the instructions on the can.

Unplug the vacuum hose from the power brake booster.

Start engine, pour in 1/2 the can of Seafoam into the hose, don't let the engine stall.

Let it sit for 15 or 20 minutes.

Pour the rest of the Seafoam in the gas tank.

After sitting start the engine.

Nothing extra to buy or install.

pouring it into the vacuum hose doesn't distribute it thru the engine as well IMHO.

You only cleaned out maybe 3-4 cylinders with the method you used.
