      Yesterday I completed reassembly of my SOHC after replacing the left head gasket. The battery was nearly dead, so I had to jump-it to get it to turn over. I don't seem to be getting any spark out of the ignition (can smell gas out exhaust pipe), but this was working fine before I pulled the engine apart.
      Before I test the igintion system, is there something more obvious I should be checking first?

      Further to my spark query- I charged the battery up to 100%, and wala, she started! Obviously the jump just wasn't delivering enough juice.
      Now I've got more questions:
      Loud noise seems to be coming from the intake area which I'm assuming could be poor injector seals (if not, what else?). I'm hoping this will go away with run time, but after three warm ups it has not.
      She still doesn't idle, and RPMs must be at least @ 1.8-2K or she sputters and stalls. Related to above? Any other ideas?

      vacuum leak?

      You may have a vacuum leak: Intake manifold vacuum lines

      Are you sure the upper intake manifold is seated correctly on the lower manifold? It's a little tricky to get all the way down. Sometimes the gaskets pop out of their correct location. Did you remove the EGR tube O ring?

      Yes, I'm pretty sure it's seated, but it was a pain in the rear, especially the two rear bolts! I did not remove the ERG O-ring, though it was the ERG tube alignment into the upperman that made seating it so tricky. I'll take another look see. Perhaps I should take the ERG tube off and put it back on again?

      I should add that the noise in question does not seem to be a vacuum or sucking sound, but rather the opposite sound of compression escaping. Initially I thought it might be the exhaust manifold, but it is not from that area.
