mobythevan Posted March 6, 2003 Share Posted March 6, 2003 I just bought a 73 240z that was in the middle of an engine swap to an L26. The L26 is mostly hooked up and has the SUcarbs from the L24 engine. There are a lot of vacumm ports not connected. I plan to bypass the heater core first to get the engine running and see if it is any good. I have a Chilton and Haynes manual, but what I need to know is what is really necessary and what can I block off. I realize some things affect idle, warm up, cold weather driving, emissions, etc. I just want to fire this thing off and make sure that the engine runs, ie no blown head gasket, cracked block, saw dust in the oil pan Does anyone have any good cose up pictures of their L6 engines so I can see how some of this stuff was hooked up. I appear to be missing several pipes and hoses, figures Thanks for any help. Quote Link to comment Share on other sites More sharing options...
Tim240z Posted March 6, 2003 Share Posted March 6, 2003 All you should need is the vacuum signal to the distributer. Block off everything else. The SUs each have a vent line going to the air cleaner (small vacuum line size tube.) If you just want to fire the engine, just block off all the heater lines.
