I have a 85 jaguar xj6 vaden plas with the original straight 6 cyd. rebuilt with about 10,000 miles on motor. A misfire or something caused a slightly bent intake valve on the last cylinder closest to the cab. when the motor is running I can pull the electricty from the fuel injection and can tell the difference, but a compression test shows almost no compression.( all other cyl. have normal compression) Is there a way to change that one valve without taking the head off. like maybe through the air intake manifold, if I take that off. If not what is the quickest way to accomplish this.
