I have a 2000 380 DA with 454 7.4 gen VI engines with 330 hr. The port motor has low oil presure and oil in the closed cooling system. Compresion was 130 to 135 in all cylinders except for #5 which was 110. The mechanice is trying to pull the port side head but the head will not come off. All bolts have been removed, does the air intake manifold need to come off? Any other reasons why we are having trouble?
