I finally have the time to work on the project I spoke of in my very first post ever to this website forum... which is a 1997 4.6 V-8 alpine green thunderbird with blown head gaskets....

I pulled both heads over the weekend and it was obvious which gasket blew... seeing as the 4 pistons on the passanger side head looked brand new (steam clean effect from the coolant in the cylinder from the blown gasket) and the 4 pistons on the drivers side looked normal (from not having a blown gasket).

I'm replacing all of the seals and gaskets I encounter along the way so that I have that assurance factor of the other head gasket not going out and everything on the engine being basically new.

While I'm in there... I'm also replacing the radiator, water pump, water pump seal, hose connecting the coolant tube in the valley, valve stem seals, timing cover gaskets, front seal on the timing cover, valve cover gaskets, exhaust manifold gaskets, intake (for one with an aluminum crossover), intake manifold gaskets, belt, belt tensioner, spark plugs, plug wires, air filter, cat-back exhaust, oxy sensors (all 4), timing chains, timing chain guides, thermostat, thermostat o-ring, head bolts, head gaskets, fuel filter, all of the fluids... including brake, trans, oil, power steering, diff. oil, gas, etc... also I'm adding an oil cooler, oil filter relocater, and trans cooler.

Now to my question can I clean the carbon off of the pistons on the drivers side? Would it hurt any to do so? Also how about the inside of the plenum? I know it says not to on the throttle body but why not? would this cause harm? I just want it all to be new and feel new and have that reliability factor that it will last for a long time to come... by the way this car has 81xxx miles on it... I want it to run like new...maybe even better than new.

Thanks in advance to any and all replys

GMacTbird seafoam sounds like it would do the trick but I'm looking more along the lines of cleaning it before I put the heads back on....

guitar maestro thanks for the tip.

any one have others suggestions? does anyone know if any harm can be caused to the engine by cleaning carbon off pistons and intake parts?
