lwrnclightner Posted October 20, 2013 Share Posted October 20, 2013 Hello, I am undertaking trying to correct some pretty shoddy work done by the PO of the 78' 280z I just landed. As ugly as the craftsmenship is, believe it or not the car runs, not like it should but I did drive it home from SC to MD. Anyway, I just received the O Rings but I think the pieces in question should be replaced also while I'm at it. Can someone tell me what it's called so that I can call Todd at Wolfscreek to try and order, (Todd does not have the time or patience to figure out what the heck a Noob is talking about). Oh did I mention that I have absolutely no working knowledge of our Z's inner workings, but I do know that since I was 7 or 8 back in the mid 70's that the Z was the car I would own one day. I have one now, and while she needs some love, I'm so excited to have something to play with. So let the labor of love begin!!!! Any help and any do's and dont's while I attempt to learn my Carbs is greatly anticipated and needed. The piece that I need to identify and find out where to replace them from ( IT goes between the Carb and the Intake manifold) A couple shots of what I'm working with and trying to correct Over all she is in fairly good condition, I have identified the expected rust, so I will be cutting and patching a little too.

Tony D Posted October 20, 2013 Share Posted October 20, 2013 (edited) Oh, you're cross posting.... Argh. Check your post at the other site. Comprehensive answers including sourcing was done there.

lwrnclightner Posted October 20, 2013 Author Share Posted October 20, 2013 Can the Modifier please delete this post. I am new and I posted the same question on another forum. I'm new to this and didn't know that "cross posting" is what I did and that it is frowned upon. It won't happen again. Thanks, Lawrence Link to comment Share on other sites More sharing options...
Leon Posted October 20, 2013 Share Posted October 20, 2013 Holy crap! What the F was the PO thinking... Those are just carb isolators, you can find them in many places including Pierce Manifolds (yes, they deal in Webers). http://www.piercemanifolds.com/product_p/99005.145.htm http://www.piercemanifolds.com/product_p/z70-216.htm Link to comment Share on other sites More sharing options...
PLATA Posted October 20, 2013 Share Posted October 20, 2013 Makes me wonder on what others mods/repairs where made with the same technique Link to comment Share on other sites More sharing options...
srgunz Posted October 28, 2013 Share Posted October 28, 2013 Pull the intake and exhaust manifold and put the studs back in the head as it was designed. The PO already screwed your intake by putting those insulators on there. They are the wrong ones. Get the weber ones from Pierce. You have Solex but uses same insulator as weber. As you are new you may be better to sell the whole set up and put SU's back on. Eveything I see there including the carbs and manifold look like junk. It will take some time and $$$$$ to fix it all.

T-Bone028 Posted October 28, 2013 Share Posted October 28, 2013 Do not get discouraged! copious carb cleaner, rebuild kits, and reading will pay you back in spades. If its running now, there's no reason you can't help it make it run better. Link to comment Share on other sites More sharing options...
lwrnclightner Posted October 28, 2013 Author Share Posted October 28, 2013 Thanks everyone who chimed in. I was informed exactly what and why these isolators/insulators where used. However I have also discovered that because the manifold was modified a little I can just go with the correct insulator for my carbs. And srgunz I can't give up, I'm just getting started LOL> The car runs so like T-Bone states, I can only imagine how she is going to run once I get em rebuilt and correctly mounted etc. Now I have to go about learning how to properly tune these babies. But it's all love for me. A learning process for sure. Thanks again Fella's Lawrence Link to comment Share on other sites More sharing options...
