anybody ever heard of this trick. i am just doing a valve job so the head is off my motor and i want to clean up around the top of the cylinders. all the carbon will fall down on top of the piston. the machineist i took the head to says to bring all the pistons midway in the bore and put a bead of grease around the edge of the piston and cyl. walls. that way when i clean up the loose carbon, the carbon drops down on top of the grease. to be wiped away later. i'm wondering about the grease that would be left between the piston and the cyl. that i wouldn't be able to wipe away. machineist says that little bit of grease won't hurt and will be washed away later when put together and running. anybody think this is a good idea???? or a bad idea too?? guess at this point it seems like a reasonable idea to me.
