+1 on this, I have had a bottle sitting in my garage for about 9 months but just don't feel very confident in doing it.

I would only do one after a can, and maybe 50k miles later (or the km equivilant).

Thank you soo much for the info! Always reliable
I will be purchasing a can when the funds become available. I always put it aside when I really shouldn't lol

Agreed, someone make a video using it with the LLT!

Is the cleaning the dealer would do better than the seafoam cleaning?

Yes! Lol I've also had a can of sea foam laying around for a while now and want to use it because I'm at 40k no can

With the utmost respect, guys, you don't need a video for this. You can do it. Trust yourself. Read the label on the side of the can. Whether you got the pour in liquid or the spray, they both have great directions. There are some good tips here specific to our cars, like the side port on the IM for the spray. Use those and the base instructions on the can, and you'll be golden.

My tip... I use the pour in liquid with like a windex sprayer that I've cleaned out. I squirt it into the PCV hole on top of the manifold while my daughter holds the engine RPMs at about 2000. Hope this helps.

Lol where's the brake booster on the LLT? I can't figure which one is which
Sorry for newb question. Think I see it but don't want to put seafoam in the wrong line

Driver side firewall. Pinch the clip and slide it out of the way. Then work the hose off the insert.

[SC2150]

Just DON'T pour to much in at a time.

Carefully follow instructions.

Doing the chain replacement:

Here are some pictures for those wanting to see the effects of no catchcan:

Here is what a piston looks like to show how the gunk buildup on the ringlands/rings prevent the rings from moving freely. Also look at the scour marks from the deposits breaking loose and being forced between the piston and cylinder wall:


No catchcan used on the left, and a average can that lets oil through on the right:


Intake manifold on left with RX can, on right w/out:

I thought it was noted somewhere that putting Seafoam in the brake booster line was not recommended since it only treated half the engine?

What seafoam procedures can I do to reverse as much of that build up as possible?

Seafoam does more than just clean fuel injectors and carbon deposits. It also is a fuel stabilizer (for those who store your car for the winter).

It also aids in the removal of water/moisture from your gas tank - which is a problem these days since the addition of ethanol to today's gasolines.

For that reason alone, my mechanic suggested I add a can of Seafoam to a full tank of gas at every oil change (or 5000 miles). I do this to all my cars.

FYI - STP now makes a version of "seafoam". Exact same ingredients used in Seafoam and the can looks the same...but it's about $1.00 less a can.

No you misunderstood this. Yes most of the time it only gets one side. But this is why you have to spray in the TB which this will get the other side. It was never said not recommended. The booster line gets the back of the engine and the TB gets the front. And when you choke the engine out with the booster line this causes the seafoam to sit on top of everything to clean it.

Thanks for the tip.
