So in cylinder #5 im losing massive amounts of compression. I took it to the dealership (originally to get computer reflashed) and had a diagnostic done and said low power point on #5. I got a new compression gauge, tested #5 and it goes up to about 140-150 but as soon as i stop cranking motor it drops to 40. Think that is the head gasket causing all my troubles? Tested #6 and 7 and they are fine, read a solid 155 and hold compression. I looked inside #5 and its completely fouled up with oil where you cant even see metal. Other cylinders have a thin oil foul, but you can see the metal and shiny spots at least.
If thats what it is whats involved? Does the motor need to be dropped? or can it stay in (its driver side) and just go through the valve covers? Or will the whole intake need to be taken off (kb supercharger). Ill probably end up taking it in if it is anything like dropping the motor or digging too far, not enough time or tools on my hands. Guess on cost?
