    Pushrod problem

    Bent pushrods are usually what happens when the head of the valve contacts the piston....severe rocker arm mechanical bind can jack the rocker stud out of the head...at this point your next step would be to buy or fabricate an adapter that allows you to pressurize each cylinder thru the spark...

    Pushrod problem

    This is a “all stop” situation....you must verify that the new cam is installed correctly ..that the timing marks are in proper alignment....usually bent pushrods = bent valves..inspect rocker studs for signs of mechanical bind..do a leak down type compression test with all the rocker arms...

    BIG Transmission fluid leak

    Here goes.... the sleeve with the o-ring is a tight fit to the output shaft...when the yoke is installed ..it fits into the sleeve and seals off any trans fluid from getting onto the splines and working out thru the vent hole.... the sleeve is long enough so that in regular driveshaft...

    BIG Transmission fluid leak

    The yoke is the problem,the hole should not be there... its actually a machining plug...its only made of tin..its either rotten or the yoke bottomed on the output shaft of transmission and made the hole.....replace the yoke...
