just pull and wire brush plugs after Seafoam/B12 or even better, give it a shot of water, 1 qt, down the TB plate at 2k rpm hot....
plugs and combustion chamber like a new engine on assembly line
Spitfires with the water injected Merlins never had a problem with fouled plugs or deposit buildup
the Pratt&Whitneys fell out of the sky like dead ducks with fouled plugs and deposit preignition engine damage.
let the Seafoam flood the engine at the end, 1 whole can in....then set and soak the crud for 2 hrs....hard freeway run with several pedals to the metal, redline NASCAR runs
run best done in the dark with no moon, state troopers frown upon gut pucking oil smoke clouds
or use a couple ounces of LC down each plug hole on vertical engine and let set for couple hours....just did on wife's CRV...noticibly smoother running engine....fuel mileage up by 2 over 5 tanks...cleans ring pack
did not get much Seafoam type white smoke from LC out the exhaust on the hotrod freeway redline run but the exhaust smell was similar to a large open garbage dump in mid summer...
wife noticed performance improvement...asked me what I had done to HER car?
