Hey All, I was all set to adjust the valves on my bone stock '73 240z, however when i went to actually adjust one of the valves clearance i found that a 14mm was almost to the point of slipping off the adjustment nut. A 13mm is too small and just for kicks i tried a 9/16 its the same as the 14mm.:sleepy: . So i'm just wondering if i just need to use an adjustable wrench (which i would hate to do) or is there a special tool needed that is a 13.5mm or something. I guess i could try to file out a 13m so i get a tight fit. What i am really afriad of is round out the adjustment nut itself. Also from what i've checked all the intake valves were snug at .010'' but ALL the …

I learned a great lesson yesterday.My old chevy46 truck has a '54 235 straight 6.Being a low compression,1 barrel carb,I never really thought much about the power or lack of.Sure I put in plugs,points the normal things.Its not real quick.It always cranks right up acts cold by poping and such underlaod until warm,doesn't rev very quick.Yesterday I decided it was time to adjust the valves.DAMN!!The cold nature is gone,it has more power than it ever has.If you told me the motor had been rebuilt I would have believed you.I've always known that the correct valve setting was important but,I had no idea until yesterday.What a great surprise!!So often overlooked yet such a critic…

Does anyone have any ideas on how to go about tightening up the slop in the throttle linkage (attached to the firewall then onto the manifold) on a 240? I can't seem to find replacement parts in the MSA or Victoria British catalog. (but, then maybe I'm just blind or missing them!!) Is "shimming" my only option? Thanks!!! Dan

Ok well this week I didn't drive my Z because I was gonna do work on it but having a need to use my car on Sunday i took it out and was being nice to it. So anyway I'm in traffic and trying to change lanes when i hear a bang. I see a bit of smoke and the engine stalls, great I think try to start her nothing crank crank crank she comes to life but I try to accelerate and it dies again. At first I thought a valve had given up but I managed to get it down a side street and start it up again at idle. Idles ok not great ok dies if you rev or try and move. Would not start then blows a heap of blue smoke through the intake. But it's running called a mate with a Z we have no i…

Gday, I just wanna run this past everyone to make sure my thinking is correct. Cylinder No5 doesnt make a difference when i pull the spark lead. when i check the plug its wet with fuel. I've checked plugs and leads and dizzy rotor. When its chugging away on 5 and i spray carb cleaner around the intake the miss goes away. So ive got a manifold leak. This only appeared out of the blue, I just finished wiring a rx7 fuel pump. I tested the pump on the car ran great. Wired it up so as to stop when engine dies. Then after that I started her up i started to get the got problem. I'm SURE the pump isnt the cause. Manifold gasket is prolly only 4-5 months old (The exhaust place i…
