Default Tell me what you know about...

Piston Soaks and Engine Decarbs.

I'll start with what I do know.

I know a piston soak in its conventional term is pretty much a nicked idea because of how our engines are designed.

However what about using the BPV line (on turbo models) to feed Seafoam, water (if you are super old school), BGChemtool, or any thing else some of you guys use.

I am aware to run it on a warm\hot engine as you have less likely a chance to hydrolock the motor, but does this method feed throughout the entire system?

Does it reach all four cylinders, what about feeding it through the PCV valve?

About engine\throttle body decarbs, how many of you have done this? I assume you would have to remove everything from\including the maf and back and then on a hot engine shoot a bunch of decarb cleaner of your choice into\on the throttle body.

Did you let it sit? How long?

Im also aware with any of this an oil change should follow as well as replacing your plugs.

Anyone else care to share or correct me on what i've said.

There are better products to buy. You can get GM top engine cleaner in a metal pour can or a spray can at a GM parts department. With the plugs out, use a 3ft 3/8" vacuum hose and pour or squirt some top engine cleaner in the cylinder. Take some compressed air and do a one second blast through the hose that will spread the fluid on the piston. It wont be a puddle of fluid soaking on the pistons but may do the job better then you think.
The spray can comes with a straw and you may be lucky enough to squirt it in that way if you have room. The seafoam and BGchemtool are nowhere as effective as this product. I used GM top engine cleaner at the Honda dealer I worked at and is where I swiped this from.

I was thinking about using Amsoil Power Foam actually because it foams up and sticks to everything.

I had a feeling that this would cover the piston and everything better then the GM cleaner.

I looked at both as viable options on BITOG.

Thoughts?

The Amsoil Power Foam sounds interesting. I would love to own a borescope and do a before and after look.

Exactly the product mentioned in www.endwrench.com for intake cleaning.
