Inliners International Forums General Discussion Engines My engine knocks

I do intend to remove the valve cover before I pull the engine. My engine has solid lifters , so that decreases the chance of a sticking lifter.I will pry on the flywheel to check for "play". I will not be able to remove the oil pan with the engine in the car. I have Mustang II ifs, using the factory Mustang crossmember and there is not enough clearance for pan removal. Thanks.
