Piston Soak vs Seafoam via intake

[skate1968]

Question 1
Will I need Seafoam via Intake after doing a piston soak? No, the combustion chamber has already been cleaned, right?


Question 2
A piston soak on a high mileage car is NOT an extrememly difficult job, right? Can I have the rookie up the street do it as opposed to going out of my way to have the experienced mechanic handle it?


Background
I've already used Auto RX on my smokin sludgemonster. Auto Rx showed good results. Now I'm looking at the top of the piston ring seals. (i'm not expecting a magic magic fix-- just want to do what i can)

Used Regane and lucas ucl in gas tank.

It's my understanding that Seafoam via Intake manifold and a 'piston soak' pretty much clean the same area. The combustion chamber.

I've read that it's possible to damage an engine when using Seafoam. Also some don't recomend Seafoam for high mileage cars.

Your thoughts?

The piston top is the bottom of the combustion chamber. The other half is the head area(the actual combustion chamber) including area under the valves. You won't clean the combustion chamber with a piston soak. You will only clean the piston top.

Yep, you can damage an engine with seafoam if you hydraulic-lock it.

An engine that is running correctly shouldn't need anything more than a bottle of cleaner in the tank 4 times a year.

#1. You could do a Seafoam smoke show to clean the combustion chamber.
#2. I wouldn't trust anyone to work on my car.

Lubegard and Berryman have CC cleaning kits with metered hoses and decent instructions to prevent issues.
