  1. No. Correct gasket. If, by chance, it had a blocked oil passage, wouldn't it run more than a minute? If it is ruined, what would be options for a replacement engine that would bolt up to my manual 4 speed? It is a 4x4.
  2. Regarding my siezed l20b. Yes it has fresh oil in it. Ran really well for about 45 sec. to a minute and seized.

  3. It won't spin with all the plugs removed. It has fresh oil in it. It ran for 45 seconds to 1 minute (really well). Then made what sounded like a dry cylinder squeal, I immediately switched off the ignition. Attempted to restart it, and got the click sound of a dead battery. Battery is new and fully charged. Then, I attemped to spin it at the crank with a ratchet and no turning it there. So, I pulled all the plugs and tried again, forward and backward. No luck. She is stuck.
  4. My engine siezed after I changed the head gasket. Got it put back together, timed it, fired it up, it ran great for about a minute, then siezed. What did I mess up? Am I screwed? This an L20B.
  5. Thank you so much. I did what you said, and now my truck runs. Thanks, you are awesome.
  6. No it doesn' t. It is pointing between 3 an 4 at tdc.
  7. I have a 1980 Datsun 720 4x4 that came stock with the ei matchbox dizzy. I sent the dizzy to be rebuilt by the guys through rock auto. They returned it stating that it is un-rebuildable. I have a hot spark HIT4 dizzy, which I installed with the proper coil, new plugs and plug wires. I am getting spark to the dizzy, but no spark from dizzy to plugs. Do I need to install a gm hei remote ignition module to make it work? Please help, I have been trying to remedy this situation for over a year. Needless to say I am losing my patience.
