I am trying to do a piston soak in the cylinders using Berryman B12 (116) and my all of my pistons can’t seem to hold the solvent longer than 5 minutes . All the B12 solvent immediately drained into the crankcase after I poured through the spark plug holes.
Does this mean my piston rings aren’t clogged or stuck closed?

i saw YouTube and the liquid should be stay inside the cylinder at least 6 hours or more for the solvent to dissolve the carbon on top of the piston.

Any inputs?

Can you provide a YT link to the video you watched?

 

 

It appears there are no short-cuts for the V6 piston soak.
Looks like you have to do 3 pairs of two cylinders, 24 hours at a time at TDC, for a 6 cylinder engine?
He sums it up starting at @37:50.

 

I know but all my 6 pistons don’t hold the solvent longer than 5 minutes. All the solvent drain to the crankcase almost immediately after I poured through the spark plug holes.

 

Try placing cylinder #1 & 4 at TCD, pour in appropriate amount of solvent slowly, then recheck.
Similar to what the guy on the video advocated for the V6 engine.
Do you have a bore scope camera to make the 'checking' easy?

 

Hey OP, did you ever get this TDC Berryman B12 piston soak process to work like the guy in the video?
