1989 C4 Functional Restoration
Time for an update though I have done very little to the car in the past month. I have been collecting parts, paint supplies mostly and I managed to get a parallel flow A/C condenser, well, actually 2 as the first was somehow run over in transit. UPS is really good at delivering labels. no...- SirReal63

Time for a short update, (short on work and long on words)...not a lot has happened with the car, too dang hot, but I have done a few things. I replaced the sun visors, this has been on my list since day one, but hasn't been a priority. I had considered rebuilding them but with plastic insides...- SirReal63

Overall update from the work I have done since October to August. I took the car out on one of our very bumpy back roads and I have no rattles of any kind, top up or down. No dash rattles, no door window rattles, no rattles of any kind. I can say without a doubt to take the time to repair any...- SirReal63

I am still chasing a high idle issue, after my check of the IAC and minimum air position, checking the TPS voltage and making sure everything is still plugged in correctly. I used my little injector pulser and all 8 injectors are pulsing, correctly it appears, so I bought a little clamp meter to...- SirReal63

I had some time to kill while waiting on parts so I tackled a little issue, the black insert on the drivers door card only had 2 points of attachment at the top instead of all 3. I decided to try and correct that. A piece of 1/8" ABS plastic, cut oversize, would fill in the missing piece of...- SirReal63

It is now officially too dang hot to be in the shop for more than a few hours each day. I had originally planned on A/C in the shop but the cheap Janus doors and the hideous expense to replace them with insulated 10' doors made that a very long term goal. I could go out there in the evening but...- SirReal63

Early in my management career my mentor told me to never change anything until you know why it was being done the way it was. This advice mostly served me well for decades, but sometimes we get off on a tangent that was flawed from the beginning and didn't realize the flaw until we step back and...- SirReal63

Since I have the doors apart it was time for some maintenance and changes. I cleaned the dust and dirt off of them, only the driver side had a water barrier on it, the bottom of the doors were thick with dirt and misc. debris that I was able to loosen with a brush and vacuum out. The weep holes...- SirReal63

The door cards needed a lot of attention, thankfully it was over 90 degrees so the epoxy set quickly, instead of the overnight issue I had with the console pieces. The passenger side was actually ok, some cracks and a little missing plastic but mostly intact. Drivers side, broken, missing...- SirReal63

Time to start on the door cards, boy, what a mess. They were bad enough that I considered buying the re-pop ones but I have read very little positive about them as far as fitment goes. It also goes against the philosophy of this thread, so I jumped in with both feet and hands. Let's start with...- SirReal63

I got the lock pillar gaskets and covers installed. The covers were a nightmare but did get taken care of. My original passenger side was intact and in great condition, weatherstrip was ok but the drivers side had no trim and was missing the upper half of the weatherstrip. I mentioned earlier I...- SirReal63

It was a good week, I got a lot done but not in picture format. I got the cooling system flushed, drained, rinsed and refilled. I got the new radiator hoses on, new serp belt on, cleaned and re-attached the temp sensor wire though I did not replace it, that will have to wait until I drop the...- SirReal63

It is often said to clean between the radiator and condenser. I absolutely agree with that advice. I am changing radiator hoses since I did the flush and decided to go ahead and open up the top to Narnia. Both rad hoses appear to be original, and that is a surprise, not as much as original spark...- SirReal63

I can't believe it has been almost a month since I updated this. I spent almost 2 weeks with really bad back pain so bending over the engine bay did not happen much. I did manage to get the AIR pump deleted, along with the associated solenoids and lines, throttle body bypass, new plug wires...- SirReal63

It has been another slow week here, my back is still out so I haven't been pushing it, I do not want another surgery on my back. In spite of the back issues, I did manage to get some more work done. Plug wires arrived and have been changed, that wasn't difficult except for being careful to not...- SirReal63

I have a different block than factory, the intake off an 88 and who knows what else. Block casting number from passenger rear is 10243880 Vortec block from 96-2000 or so. I was unable to get to the casting number on the driver side rear, too much stuff in the way but did find 288 and a clock...- SirReal63

Things have escalated this week. I really needed to get to the vacuum line for the HVAC but there really is no way I can get my booger hooks into that small space. In addition I had wanted to remove the air pump and had ordered a delete bracket to do the job. I started taking things off in...- SirReal63

I got the AC low pressure switch installed, fan clutch kicks on but goes on and off every few seconds. I suspect the charge is actually low and that is causing the cycling. I am going to wait to recharge it as I want to replace the o-rings on the system first. It does cool well at the current...- SirReal63

It has been a busy few weeks, as usual, more so now that Spring is here, lots of other chores to do and not much time for the car. I got everything under the car put back into place and tidied up. Some interesting things learned, the P.O. said the exhaust had been worked on but did not...- SirReal63

I did not have a speedo or reverse lights. It took a little while to get the cross brace off, the exhaust off and to diagnose the issue. It turns out the issue with the speedo was the drive gear clip had broken and while doing so mangled up the drive gear. The driven gear on the VSS was perfect...- SirReal63

It has been a busy few weeks, not a lot of work on the car but still progress. I had a plan for the stereo head unit replacement, a cheap Android unit on top and a half din EQ on the bottom. I gathered up my supplies and dug in. The primary reason for the change from the old JVC CD player was I...- SirReal63

It has been a busy past few weeks, not a lot to show in pics but I have also been doing things other than working on the car. I need to get the interior done before lifting the car and working on the mechanical things. Let's start with the center console lid. This was really showing it's age...- SirReal63

I also worked on the carpet some more. The rear was actually good for color but the front was sun-faded badly. I ordered 3 cans of the "correct" SEM Cognac dye/paint from Mid America and tried to bring it back to the original color. Since this is really a paint the color of the substrate effects...- SirReal63

It has been a busy week but not a lot to show in pics. I managed to pick up a nasty cold so that put a damper on work. I did more dash crack repairs, this is the lower console where it attaches to the tunnel, both sides of this were cracked and no longer attached. The passenger side was not...- SirReal63

The finished repair of the broken dash mounting tab. I pulled the knee bolster to check the wiring under there and found it surprisingly clean for the age. A little dusty and several pieces of dash plastic debris but no droppings. I am surprised by one thing more than any other, I have...- SirReal63
