Re: valve adjustments for 3.0 volvo penta
This is from a Merc service manual, but it's still a 3.0L Chevy engine. Sure hope you are torquing the head bolts properly and in the proper sequence with sealer.<br />What NO manual????<br /><br /> Engine Not Running <br /><br />With valve cover removed, adjust valves when lifter is on low part of camshaft lobe, as<br />follows:<br /><br />1. Crank engine with starter or turn over in normal direction of rotation until mark on<br />torsional damper lines up with center 0 mark on timing tab, and engine is in No. 1 firing<br />position. This may be determined by placing fingers on No. 1 valve as mark. If valves<br />move as mark comes up to timing tab, engine is in No.4 firing position and should be<br />turned over one more time to reach No. 1 position.<br /><br />2. With engine in No. 1 firing position as determined above, the following valves may be<br />adjusted:<br />No. 1 Cylinder - Exhaust and Intake<br />No. 2 Cylinder - Intake<br />No. 3 Cylinder - Exhaust<br />No. 4 Cylinder - Intake<br /><br />3. Loosen adjusting nut until lash is felt at push rod, then tighten adjusting nut until all lash<br />is removed. This can be determined by moving push rod up and down while turning<br />adjusting nut until all play is removed.<br />72300<br /><br />4. Hydraulic lifters can be adjusted by tightening adjustment nut an additional 3/4-turn.<br />Valve lash should be checked after engine has run and reached operating temperature.<br /><br />5. Crank engine one revolution until pointer 0 mark and torsional damper mark are again in alignment. This is No. 4 firing position. With engine in this position, the following valves<br />may be adjusted:<br />No. 2 Cylinder - Exhaust<br />No. 3 Cylinder - Intake<br />No. 4 Cylinder - Exhaust<br /><br />6. Repeat steps 3-4 to adjust other valves.<br /><br />7. Install Distributor cap, spark plug wires and coil lead.<br /><br />8. Install rocker arm cover.
