hey everyone i just bought a 95 es300 from my friend (whos a toyota freak). and the car had a spun rod so we took out the motor and started to do a bottom end rebuild. now the car had been sitting for a while so alot of sludge built up in the heads. we took them off and took out the valves and tried using degreaser and carb cleaner with a flat head to get out all the sludge but its just not cutting it,,,any ideas on how i can clean up the heads to get the best performance out of them???

I heard marvel mystery oil is pretty good at clearing that stuff up, but i have no idea

Take them to cylinder head shop and have them hot tanked

thanks guys,,,mit im tryingto avoid bringing stuff to a shop due to LOW funds lol...ill give the marvel a shot.....does anyone know if using a pressure washer would be a bad idea ive been getting mixed answers on yes or no...id imagine itd be ok as long as i dont leave water sitting in the heads right????

See if this video helps.

thanks..it helped with info i just dont have those kind of tools or space to go through all that,...i was thinking about using a pressure washer with degreaser and just immediately drying off the heads before any rust starts forming
