   Car sitting since 99....pre-start suggestions?

   I have recently picked up a 1972 240Z that I plan to restore. This car has been sitting for quite sometime....since 1999 to be exact. I plan on draining and cleaning the fuel tank of course, but was looking for suggestions on what to do before attempting to turn the engine over....such as spark plug removal and spraying lube in the cylinders etc. Any suggestions that will make this a less stressful event for my engine would be welcomed. At this point....actual starting of the engine is not important.I am just making sure it will turn over first. Thanks loads!!

   What is an original 82k l24 motor/tranny worth?

   There is one on ebay with more miles than mine right now for $450 starting bid. Is it worth that much? Is their a demand for this engine/trans? I'm just wondering because i never thought that the original setup would fetch any money. If it does i may be closer to a motor swap than i thought. What do you guys think?

   Ring gaps and gap-less rings

   Can anyone tell me (from experience) what the acceptable piston ring gap should be on an L28 with standard sized pistons Have read all the books (How to rebuild, Haynes etc) and it varies from 9 thou to 18 thou, however I am just installing new rings on some dished pistons and without gapping them I am seeing 20 thou on both top and bottom sets. The bores look good (86.02 - 86.03 mm max and practically no taper) with cross hatch honing marks clearly visible (engine has only done 5K since last rebuild) old rings show 22 thou and car made 158 Bhp at the wheels when last dyno’d. Moving on from this has anyone used total seal (or such like) gap-less rings ??? Phred it would…

   240z gas tank ventilation

   Some time ago I replaced the filler hose of the gas tank. Since, I observed that when the tank is filled up, I start to have a dust streak on the rear fender under the gas door as like some vapors would come from under the rubber flap and run along the fender and down to the bumper. There is no smell and the gas cap seems very tight. Any idea about the source of this problem and how to fix? Richard

    Need Help! Which cam dowel hole is stock on 240?

    I am changing my cam and did not mark which of the 3 holes in the cam gear the cam dowel belongs in. I have an idea which one just by looking but would like to be sure. The old cam got a lobe ground down by lack of oil due to the external oiler's gasket failing which cut oil presure to the lobes. Just got the car Saturday and went to adjust the valves and found this out. Thanks in advance, Nelson

    Hello fellow ZERS' Does anybody out there suffer from aggressive throttle syndrome? No, not the need to mash the throttle down at any given opportunity although I do tend to suffer from it on occasion:classic: This one is your starting out, push down on accelerator (pretend theres a cop next to you) no response, alittle harder and it snaps open, not full throttle mind you, maybe 2krpm. I've lubed all fittings, thats not it. In looking at the linkadge, I think its in the design, just to Roob Goldberg. Has anybody done a mod to remedy this? Maybe a helper spring or something? I can feather the clutch and get around it, but when rounding a corner and dropping into second …
