several symptems,
I have white smoke and smell antifreeze,starting from the back cylinder #1 plug electode is white but dry #2 plug is wet but not gas #3 is carbon coated #4 is carbon coated.I put my hand close over the top of stack and I get a major vacume pulling my fingers down in steady fashion as if it"s one cylinder doing it every fire. Incredibly the engine still runs strong under load. I can understand why #2 is wet (antifreeze),but why wood #1 be clean and dry and the two front cylinders be carbon. Too much going on with these cylinders. any insight on all of this! .....I appreciate your comments.
 
Well best guessing.
#1 cylinder is at the radiator, not back
If the plugs are not connected to the correct cylinder it will cause issues.
If it actually has antifreeze in the exhaust the head has to come off any way, so do that. Jim
