In tdc on the timing gear i can not get a feeler gauge in either valve on cyl 4. Is this the problem?

Yes, are you sure the lifter is on the heal of the cam lobe?
It may not be what is causing your problem right now but when the car gets
out on the road and the engine heats up you can burn a valve.
