This isn't a very big emergency but a litlle help can go a long way. I am trying to replace the Throttle Rod Firewall Boot/Seal and I have a pretty small window of time to try and get it done. Anyone know the quickest way to go about this without having to remove the entire acellerator assembly? I see the little nut inside but everything is so delicate I didn't want to overcrank it and damage it. Any suggestions would be greatly appreciated. :classic: Thanks, Darren

I got it set at 10 degrees atm which is fine but the idle is at 1500-1750 rpm ..... i havent cheack the throttle body except for air leaks but i wouldnt know what to check besides the air leaks..i checked the air boot thats fine.

HI guys, I am back from school for the weekend and my girlfriend is all tied up with school so that leaves time for the other lady in my life. I think I have recently messed some stuff up on my car (again). Here are my questions. 1. Where do all the hoses on the intake manifold go? They are plugged right now. (I have no smog stuff and weber dgv's) 2. How can I tell if i need new points, rotor etc.? 3. Can I hook my stock distribs vacum advance to my DGV's? (if so where) 4. I try to set the timing but the mech advance on the distributor will not turn that much. Can it be that out of whack? (or maybe I am going for the wrong notch...) 5. Oh and also how DO you you set t…

I have an L28 with the MSA intake mainfold for an Eidlebrock carburetor. All of the pollution controls have been removed. The car runs great, but the crankcase ventilation pipe worries me. It has been capped. It seems to me that I should be getting rid of all of those noxious blow-by products in the crankcase so that they don't gunk up my oil. Any thoughts on this? (I'm using a air filter on the valve cover breather). Thanks in advance,

I just checked the compression in my engine with a compression gauge, holding the carb open and the throttle flat to the floor with a warm engine. Came up at 100 in all cylinders. Is this good for a stock L28 with a 8.3:1 static compresion ratio? I have a feeling it should be higher. Any ideas?

Ever since I got my Z back on the road I've noticed liquid coming out of the exhaust. I don't mean the occasional drip, I mean if I leave the car running in the same spot for 5 minutes a small black puddle will start forming from the spray. It doesn't smell like fuel, it's not clear like water (I'm not loosing coolant), and it's too thin to be oil. Any ideas on how to stop this??? It's made my Supertrapp muffler turn black with crap all over it and it's just driving me nuts!

I'm talking top-to-bottom on a stock L24 by a Z expert. Valves, carbs, dizzy, all filters. I'm considering have a pro do my Z cuz I'm a newb and I just don't seem to be able to get it right. My mileage sucks and he claims he can get me 25mpg. In the long run it would be worth a few hundred for a tune. How much do you think a complete tune will cost?

Does anyone know of a product that I can coat polished parts of the engine bay with? eg Intake, carb tops etc. It'll obviously need to withstand the underbonnet heat without any discolouration or flaking etc? I heard somewhere about a polyurethane based product but havent heard anymore about it. Anyone got any ideas/experiences? Cheers

I have recently purchased '72 240 with a '73 engine. I noticed a rattling sound and found that I have an additional wheel in front of the wheel comming out of the engine that does not have a belt on it. (Possibly for an AC unit thet the 72 doesn't have) This wheel is very loose, but not loose enough to pull off by hand. My question is this; How is it supposed to be attached? A center bolt? There are also two holes that line up with two nipples on the wheel that connects to the engine. Are those possibly screw holes. And would it be better to just remove it? Or does it act as a counterbalance? I am not a mechanic by any stretch. This is my daily driver so before …
