Ok so I did the grounding check for the guage and the gauge went up but it did it really slow. It in no way shot up. It crept very slowly. Also before my friend got to my house to help me with this I was playing with the connection, wiggling it and what not, and when I started the car it read out good pressure readings, like about 40 at 1500 rpm(idle), but i did take the actual sender out when I was looking stuff over so maybe it had to readjust or something? anyway a little bit later it returned to its lazy self. Im thinking it is the guage, not the sender. Does anyone know how difficult it would be to change that? I only looked briefly, do I have to take apart the dash or does the single guage pop out? shepp

Well I didnt have a chance to work on the car today due to excessive schedule, but I can clear some things up. First, beandip i have the carbs tuned so that it idles high, around 1500 actually. I bought the car right after the engine had been rebuilt. He ran it for about a week but then had to work on his new house that he and his fiance just moved into. He's a cool guy and I can talk to him tomorow. He is a master tech at saturn. Pirosan and sideshow bob i will also try your recomendations tomorow. Thanks everyone for your help and I will keep posted. shepp

Hey everyone I'm new to the forum. I just picked up a 71 240z that has just had it's engine rebuilt, hasn't even been broken in yet. I was letting the car sit at idle before I adjusted the carborators when i glanced over and noticed that the oil pressure gauge was pegged at the bottom. I gave it a little gas and it raised to about 20. After letting off it soon returned to the bottom of the gauge. Also when i give it gas a small blue cloud is puffed out. The weird thing is, if i drive it around a little bit it will stop spilling out smoke. I can even let it sit after that and it still wont smoke. I pulled a couple plugs and there weren't any signs of oil, but it was running rich earlier so they were carbon black, but not wet/oily. I am hoping that this is just caused by the break in period and the rings haven't had a chance to seat yet. If anyone has anything to ad please do.(Checks I can do to make sure the pressure is fine, or anything else). thanks adam shepp
