Restoration of 71 240z


Recommended Posts

I haven't been good at keeping up the postings on this build. It's been one bad thing after another but finally getting all straightened out! Finally got the car back to my shop around the end of September and there were some serious problems with the Paint and Body. I don't want to bad talk anyone but basically the whole process wasn't managed very well by my friend who was taking care of that process for me. They essentially did all the paint work without first reassembling the car to make sure all the gaps and reveals were good. Also the one body line doIMG_5106.HEICwn the middle of the car was different from one side to the other. I was pretty unhappy to say the least but in the end it was made right.....they just had to do the work all over again the correct way.

 

Trying to attach pictures but they only show up as attachments...Got to figure out whats going on with that.

It was BAD! Overspray all over the place, contaminated paint spots. The finish on the hood was horrible. Nothing like Epoxy Primer all over the fresh powder coat on the crossmember I was so careful to get looking as nice as possible.

Winter is the slowest time for my business so after the paint job was all done and buffed out I was able to spend the next few weeks at the shop putting everything back together. I should have taken more pictures but I was so focused in on getting this project that had suffered so many stumbles along the way done and back home.

The hood was an absolute mother to get lined up where it sat down correctly when closed. I wasn't sure if it was my hood or the hinges but we finally got it lined up. This was before the respray though. Didnt want to fight with it after the paint was done and risk scratching and messing up the paint. Instead of removing it to sit the engine back in we chose to bring the engine and transmission in from the bottom. Wish I would have gotten a picture of that! We had the car at least 3' off the ground and used a creeper to wheel the motor under the car. Then used a forklift VERY CAREFULLY to hoist it up from the bottom. I was skeptical it would clear the crossmember but it went in fine.

That valve cover is NO BUENO! I struggled getting it clean and eventually resorted to wire wheeling it to remove the old crud that was all over it. Luckily I have a few others and found a place near me that does vapor blasting. That should look a lot better.

I was dying to see if the engine I rebuilt would actually run. I followed the instructions but I have never torn into the bottom half of anything before. I was very nervous about the startup.

First start up! It took a while but finally got everything flowing and running. NO OIL PRESSURE! Now its been almost a year since this car has run. I didn't have very much time with the car before I tore it all apart but I thought the gauge was fine and I installed a new pressure sending unit on the block. I was freaking out at this point wondering what I had done wrong. We took the filter off and it was totally dry. Oil pump wasn't working. Filled the filter up with transmission fluid and squirted some in that passage and tried again. This time we got good pressure. Ran the engine a bit more with the filter off to push all the trans fluid out. There was an airgap I supposed in the pump. Just couldn't get enough pressure to start picking up oil. I was told later to pack the oil pump with grease or fluid next time to give it something to build pressure until it can start pulling the oil.

At this point it was running but something still wasn't right. It wouldn't idle smooth and we couldn't get the carbs dialed in. Sprayed brake cleaner all around the exhaust manifold and the area where the carbs sealed with the Intake and as soon as the spray hit the engine it would smooth out and run good for a few seconds. We had pretty bad vacuum leaks at the headers and the carb to intake. 

I feared the headers weren't going to seat up correctly when I was installing them due to the angle of a couple of the pipes coming off the flange. I should have looked over the carb assembly too before installing it because straight from ZTherapy there was one gasket they had missing a bolt hole with. The carbs were easy, simply took all of that apart and fixed the gasket and used a little silicone to put it all back together.

The headers were a bit more involved. Removed them and had to heat and reshape a couple of areas where we could get the proper studs in place and use the fat washers that bridge the gap and hold everything tight to the head. Just more work but after we got everything put back together the vacuum leaks were fixed and we were able to set the time and adjust the carbs.

All in all I am pleased with the Headers and exhaust from ZStory. I think the problem with the pipe angles has been addressed and the car sounds great to me. This is my first Zcar and I have never driven or been in another but it sounds very nice inside the car and out. Has enough sound to make it tough but not enough to wizz the neighbors off!

This is where I stopped taking pictures and got to work. Most everything else was just putting all the parts back on. Still more problems to come but mostly just annoying old car stuff.

Had some wiring issues that took me a while to figure out. This car had dealer installed AC, I didn't put that back on though I may change my mind when summer rolls around and I'm sweating profusely all over my armor-all'd seats. Car seems to have plenty of power and it should handle AC without making it sluggish. I had some of that wiring for the AC jacked up and the whole thing with the blower motor wire changing colors was confusing. Somehow I had something connected that energized the radio housing! 

Wheel Cylinders started leaking, were working fine before but I guess they didn't like sitting on a shelf for a year. Ordered rebuild kits since this is a '71 and the replacements cost around $350.....PO must have already did the conversion to the later model cylinders cause that kit definitely wouldn't work.  

Ignition switch is wonkey now with the key. You have to persuade the key just right to turn in on and off and now the key will come out when the car is running. Not sure what that's about but I have a new switch ready to install. 

Of course after I had everything put back together and the new door cards on before I realized the locks wouldn't work and the windows weren't tracking right. If I do another one of these cars I should be able to cut my time in half after all the boneheaded things I have done on this one. Should have checked all of that before installing the door cards which aren't a breeze to install with the new clips. Locking problem ended up being simply the little plastic ends that are on the rods that connect to handle to the latch were ran out too far and wouldn't let the latch return enough so the locks could engage. Sounds easy but that was a head scratcher!

Worst of all is the windows. Got the Passenger side working pretty well but the left side is giving me fits. Window tips down in the frame on its way up. I've used this site to search on the adjustment and I'm sure I have all the adjustment I can to solve that problem but its still off. There is some slop in the track that the white roller bushings slide in. Best I can figure that slop is giving the window room to dip. I didn't have the roller guides on this car and now have those to install in the next day or so but I think that is more of a fix for the window leaning towards the outside. The white roller bearings/bushings are of course out of stock.

Hey she looks great, worth all the extra work to get what you want.  Seeing that poor paint work for the first time  must have been soul crushing, hope they cut you slack on the bill.

It was brutal! I've done the best I could and always knew I probably wouldn't end up with a Concours product. That being said I did expect a very nice finished product that I could be proud of....This was FAR from that.  My hats off to everyone here that is spending the time and money to get to that level! I can't imagine how long it takes and how expensive that becomes. I had an idea in my head how long this would take and how much money I would have in it......I have doubled both!

The guy that ran that shop was pretty embarrassed and did the right thing. In the end they did a nice job at their expense the second go around. Me and him are fairly close though, It could have been really bad if it were with someone I had no relationship with.
