#6 is filling up with antifreeze causing it to misfire. i brought to the dealer and they fixed a leaking hose and sent me oin my way. 450 miles later it has happend again. i have looked for a leak but can not find one. any suggestions before I retun to the dealer and take it in the shorts?

 

if coolant is getting in the CYLINDER its either a bad intake gasket or head gasket or cracked head..is the coolant turning to foam in the radiator?..DO NOT CHECK HOT IT COULD BE UNDER PRESSURE and hot foam is no joke...check it out...zap!

 

i think what he means is that it is getting in the hole on the outside of the plug, caussing plug and coil pack problems
i am having the same problem with my 97 , 5.4. just to busy to stop and figure it out.

 

No. it just seems to be filling the hole that the sparkplug is in and the plug is sucking it in... if that is possible.

 

I don't think the fluid is getting sucked into the cylinder. The water is leaking from the hose and filling the spark plug well. Once there, the heat from the engine makes it evaporate. If you can't find the source of the leak, I would take it back to the dealer and have them check their work, and reapir it if necessary.

 

Can't take the misfiring! The red sleigh is going to the dealer for repairs Friday.

 

my 98 4.6L had intake gaskets leaking causing the same problem as you are having. My truck kept getting air locked caused by pressure build up as well. Changing there gaskets are time concuming but fairly easy. Let us know how you make out..
