   Looking for info on the 260 air cleaners. Restoring the one we have, plan on upgrading from the flat tops to round tops and keep the original air cleaner, going to use Ztherapy's adapters with TWM Induction air horns. I see what looks likes it at least one decal on it. Anyone know more about them, pics would be great. Thanks, Jim 1974 260Z - RLS30-020697 (01/74)

   Carbs?

   I have a problem with my 72 240z. Say the car is in third gear on a very slight grade upward, the rpms are slightly below 2500 or at 2500 and gas is given; the car chokes itself. There is a lurch like the engine is lacking fuel. Is this the carbs? A problem with compression? not really sure. My dad thinks its the carbs. Could be. thanks

   white smoke?

   I just bought a 78 280Z that ran perfectly fine while test driving it. It needs some brakes and wheel bearings though so I have had it sitting in the driveway for about a month now while I buy all the parts. I just finished putting on the new brakes and went to take it out for a test drive and when I started it up I filled the whole street with white smoke. It seemed to let up a bit after I drove off. As I was driving it was hardly there any more. I used to have an 83 Z years ago but I don't really know very much about these cars. What should I have checked out? Is there anyone here in the Kansas City area that knows how to work on these? I'm hoping the guy who sold me th…

   Hesitation

   When I start my 72 240Z, it takes quite awhile for the engine to warm up. It hesitates real bad and actually pops after it starts to speed up. What could the problem be? Put some carb cleaner in the gas tank and some water treatment. Any other ideas?

    Valve cover sealant?

    September 20, 2004 by Ed

    I've been polishing my valve cover for the past few days. And I've noticed that the inside of the cover has a "sealant" around the baffle plate. This "sealant" is also around the vent tube on the outside of the cover. (I'll take pictures if anyone doesn't have a clue as to what I'm talking about.) This "sealant" is cracking and falling off. Does anyone know of any alternative for this or has replaced this with an alternative material that works?

    Rocker arms, new or regrounds?

    Just got a new cam (regrind on my original) 269/269 473, should I get new rocker arms or have mine reground by Delta Cams? Some people say get new OEM, whiule others say go with the regrounds. With a 473 lift, shouldn't I get new performance springs since new stock springs, I think, are only good to a 460 lift? Of course I have to get new lash pads, I think I will need 170 or 180. Thanks Keith.
