Cylinder 3 misfire please HELP

try leak down test

 

If you pull the number 3 plug what is the coil look like Is it got red dust on it do all the coils look the same? Pull the plug out of the number three cylinder do you see little micro water droplets on the part that's sitting inside of the combustion chamber below the threads? Smell it move away from the car do you smell coolant on the tip of that plug If so there you go there is coolant getting in that cylinder somehow and generally it's the head gasket that seals that up all the way across all four or you're missing a piece of metal along that seal surface around number 3 whichever it has to be pulled apart to be looked at You can run leak down tests and stick borescopes down there to your old. Really might not ever see a thing A well done leak down test should give you the colors you're looking to see You may have to do it twice.

 

What was the miles for:

1. Head gasket replacement
2. EGR cleaning
3. Current

 

i say if head gasket not done right it will blow prematurely
