What Goes Around

May not be going around in the right direction. I've been plagued with why my power steering had no pressure, and had a revelation today as I was meditating. Clockwise is not the same as counter-clockwise. I told my wife the pump was mounted backwards and spinning the wrong way and her simple solution was just bolt it on the other way. Not quite so simple. Rather than mucking with the accessory mounting points, it's time to just replace the LT1 pump with it's reverse rotation with a CTS-V pump designed for the accessory bracket I have. 

Slow progress over the last month, but checked a few things off the list. Finally got the instrument cluster bolted to the dash. The designer should be shot - cluster sits in front of the padded dash - trim the excess foam out, but it still needs to compress the vinyl a bit to fit. Solution was for me to be under the dash on my back with a couple pin punches, and my wife to be sitting on top of the seat and using her feet to push the cluster into location.

Headlights working (on low beam - thing the relay is out for high beam), taillamp and stoplamps working, fan working, voltmeter working. Still need to debug the tach. Wires dressed under the driver's side of the dash. Need to do the same on passenger side where PCM sits. Always lots to do.

Birthday Cleaning

Earlier this week I polished and waxed the car for my birthday. There's still quite a few pieces of trim to finish putting on the car, but she's starting to look like a finished car.


Front shot. She still needs front bumper, grille, and left lower eyebrow and lower grille surround.

Driver's side still needs the door post, upper fender trim, door trim, and door lock.

Back is pretty much complete.

Right side pretty much same state as the left, needing the door post, upper fender trim, door trim, and door lock installed.

Windows still need to be installed in the doors, and the stainless trim around the doors and on the deck lid and glove box door.

She still looks good just the same.

Took my granddaughter for a quick trip up the street.

Got SuperCooler

Installed the largest B&M supercooler available as a transmission cooler, since the BeCool radiator has no integral tranny cooler. This cooler is twice as thick and 50% taller than the previous cooler I was running. B&M recommeded I at least run the thicker cooler, but went the full distance for an additional $16 dollars. Hopefully this will give me long life out of the transmission.

Given the routing around the bat wing pan, I just opted for braided line from the tranny to the cooler. I should put a heat shield where the line runs close to the exhaust, and add some abrasion protection so I don't have braided line cutting through aluminum parts.

Summit Racing gave me a challenge in the installation. I ordered a pair of 3/8 inverted flare to AN6 adapters, but got caught with a misship, where one of the packages inadvertantly had a 5/16 inverted flare to AN6 adapter. To temporarily get things together I made a short tube assembly with 3/8 flare on one side and an AN6 tube nut on the other, and used a AN6 male-male fitting to finish the job.


 

Got Bumpers a.k.a. Gilligan's Island episode 39

My lovely wife now grocks the Gilligan Island references on the car. The rear bumpers are stock - the rear fenders are not - they have a slight bulge flaring out to clear the 275/40R17 tires. Fitting the bumpers consistend of elongating the mounting holes, test fitting, and repeating the process until they fit. It also required making a shim for the outer mount to kick the bumper out far enough from the side of the fender, and a shim under the side mount. I had some rigid plastic known affectionately as Dam Rubber, not damn rubber, due to it's past use as air dam material. In a previous life the stuff was anti-static work bench mats. I made the shims out of that material. Once everything was fitting well, I was able to locate the hole for the side bumper mount and carefully drill through the pretty paint, hoping I got the location right.



After doing all this work, I cleaned and waxed the back of the car, then started mounting the bumpers, discovering I needed a bit more shim - one hardened washer on the upper outer hole between the plastic shim and the bumper, and needed to elongate the side hole to line it up. I also had some cross-threading on the outer right mount, so it was a couple hours of tedious work to get the right bumper on, then a much quicker 20 minutes on the left bumper. I am happy to report that no paint was damaged in the process.

Since May, I've knocked a good dozen entries off the to do list, but the list seems to keep holding at three to four dozen major tasks to go. Then there's the little mistakes like putting the tumbler in 180 degrees out on the glovebox - it drops in, but doesn't turn and doesn't come out without carefully drilling a hole in the lock housing to release it. There's also the sequencing mistakes - like mounting the rear license plate and chrome surround, then realizing that the license plate lamp housing goes in first. With all these time sinks, I've decided final interior assembly will be farmed out - looking at what other stuff I can trade money for time to finish this car and enjoy some road time this summer.
 

Air & PCM

The cold air intake system was finished before the fourth of July. On the left is the new right turn that goes through the radiator support and into the engine bay. I ended up fiberglassing together the aluminum pieces. It could have been welded, but I had the materials and skill to do it with fiberglass.  Several hours of work to save three quarters of a pound, but more importantly, it makes a clean transition along the radiator support. A silicon coupler joins to the MAF/MAP sensor, then the 90 degree aluminum bend brings it into the throttle body. Not pictured, but on the other side of the radiator support, a 45 degree silicon elbow brings it under the hood down to a 90" bend and down to the air filter.

 

The PCM mount was another three hour tour - probably one of those to be continued episodes. The pins on the right side go into firewall insulation hold-down grommets, and the left side bolts to the under dash birdcage. Hopefully not too much lost footroom for the passenger, and clear of the kick panel and speaker.

 

Early Father's day treat

Today spent time fitting up padding and carpet, and putting seat belts and seats in the car. Still need a little final fit on the carpet and to glue it down, and bolt in the seats, but it's beginning to look like a car. After getting the interior semi-functional, I took the car around the block for the first time. Susan was a good cheerleader and camerawoman. http://www.youtube.com/watch?v=z3WVfdkkgos

Still kinks to work out, starting with figuring out what's up with the power steering or lack thereof, but it was nice to make a loop around the block.

This past week I was working on an airbox to make the transition through the firewall. Version 1 met an untimely death on the chop saw along with a saw blade, but no bodily harm. Version 2 took about a quarter the time to get to this stage of prep. Now just need to have a friend weld it up.

 

On the road again

This was the second consecutive weekend of working on the car again after the long bathroom remodel hiatus. There were a number of Gilligan's Island three hour tours, finishing up reinstalling the radiator, replacing the power steering reservoir with one that the hood can close over, securing the 5.3L truck fuel rails on the LS1 intake, and even replacing the battery - new optima has a different top than the old one.

One successful modification was rev 2.0 of the transmission shift linkage arm. This has been done for months, but the dead battery restricted testing. Mutt successfully traversed from the lift to the driveway, engaged park for a well needed interior vacuum, and moved back to the lift under it's own power.

The power steering reservoir was a rev 3.0 - the original bracket for the old LT1 reservoir that ended up not fitting, then rev 2.0 and 2.5 for the new one prior to installing hoses, and a final rev 3.0 with the hosed installed. Fortunately, it's a simple bracket from a piece of .090 gauge aluminum with four holes and a couple mild bends.

The next fabrication is for the air intake. I've been struggling with that one - how to make the transition from one side of the radiator support to the other - with the larger track to the new LS MAF,  the tubing is too close to the radiator to use a nice manderal bend. The solution looks to be to make a nice box for the transition with a tubular inlet, a radiused corner across from the inlet, and a transition on the adjacent side to a tubular exit. I'll fab it up this week and get someone to weld it up for me to solve this dillema.

Bathroom 1, Corvette 0

Between a home bathroom remodel, a trip to China, and a ten day trip to the bay area, the Corvette was neglected for ten weeks. I'm happy to report that Susan and I are very pleased with the bath remodel, and the garage picked up a nice big subpanel and lost the washer and dryer. Can't complain about more power and more space to work, and Susan won't bump into the lift doing laundry anymore.

At this point it was time to start doing some time / money tradeoffs on unsuccessful fabrication efforts. The first was reuse of the 1993 Corvette LT1 dual fan setup. I had tried to make a new aluminum shroud to accomodate the fans and clear the larger 4" air intake for the LS motor. That project was doomed from the moment it put the first blemish in the new paint.


The fan is a 16" Spal with the Be-Cool rebranding mark-up for the included hardware kit. A set of universal brackets mount it to the radiator.

Universal brackets are, well, universal. In addition to trimming off the ears at the fan on all the brackets, this bracket required a notch to clear the mounting pin for the radiator.

The project was a success, with an inch of clearance around the air intake once I rotate the offending hose clamp.

Back at it

It seems like September, October and November got away from me with a couple trips to China, a family reunion, some ministry work, a kitchen peninsula range hood install, and a backyard landscaping project. Thanksgiving I took the week off, but with a couple visitors over that week, I only got a few hours in on the project. Christmas I took two weeks off work, with a goal of getting back to work on the car.

Back in August I was struggling with power steering routing, and had a few other things that seemed like giant conundrums. Every project seems to have some of those. With a few months away, and several days to work through things, managed to get back to making forward progress. Power steering is now plumbed, heater box is reinforced and back in the car, and a host of other small tasks knocked off the to do list. Of course, for every couple of steps forward, there's a step back.

Friday, January 6th, the car made it's first movement under it's own power, only to find that park wasn't fully engaging - looks like the shifter linkage lever I built needs revision. I should have figured that one out when the car wouldn't start in park. Of course, the ebrake wasn't installed yet, so it was a quick run up and down the driveway, just long enough to turn the car around to have proof it actually moved. Ebrake is now installed, but there's a few more things to knock off before the true maiden run of the car - then lots of little stuff including windows, interior, and exterior trim before it's done. God willing, it will see the road this spring.
