I believe that I have found a “patch” for my current transmission problems.  Thanks to Joe Dzwil, I was able to install a Techpak-Fitzall Chrysler Axle Stabilizer Bearing (part# 32125LRB).  It’s a neat little unit that installs in place of the stock seal and oil slinger in the trans.  It has an integral roller bearing and seal that rides on the sealing surface of the axle.  A good axle with a smooth and clean sealing surface is required because the roller bearing uses the old sealing surface and the new seal uses the very outer edge of the sealing surface, which will be rusty and dirty on a new axle.  The extra axle I have was in good shape.  Some sandpaper and some rubbing compound later, I had a nice bearing ans sealing surface.  The bearing also has some gripping splines to keep it from spinning and an oiling hole that matches the oil feed hole on the trans.

Before installing the bearing, I fully drained the transmission so that I could clean the surfaces properly.  I did an “Ed Peters” to it by drilling out the hole in the square-shaped boss on the bottom of the differential housing, and tapping it with a 3/8″ NPT tap.  Once it was drained, I plugged the hole with a brass pipe plug using solvent-safe PFTE thread tape (the yellow stuff).  Getting good threads in the boss is tricky because it is slightly too large for the first 1/8″ or so.  Use a slightly smaller drill bit than is required by the tap.  Now I can change the fluid completely without pulling axles or removing the side cover.

Looks like the CSX will be at the SDAC Chicagoland meeting after all!

Well this new tranny appears to have a serious problem.  I noticed a bad fluid leak coming from the left axle.  I figured that maybe the seal went bad.  So, I pulled the axle only to find the seal in good shape but the axle had a lot of play in the differential.  I put a tight-fitting socket with an extension into the differential to see if the carrier bearings were shot.  I could not make the differential move within the transmission case…it was very solid.  Upon further inspection, I noticed that the axis on which the axle “wiggled” was on the axle shaft itself between the CV joint and the differential spline.  It appears that the differential case is worn out.  The axle shaft also has some wear on it.  I have another axle (which actually came with the trans), which has no wear on the shaft at all.  This axle was a bit more solid, but still pretty sloppy.  Looks like I will have to pull the trans.  ARGH!

Well, I have done a lot of work to the car over the past months.  Basically, I have been gathering all the parts I need to replace the head on the car.  The head that came on it is shot, so decided to try a reman head.  Big mistake.  I have never seen such crap work in my entire life!  Here is a short list of what was wrong with it:

• Someone took a bad belt sander to the back of the head, ruining the sealing surface for the manifolds by putting 0.02″ gouges in it.  I managed to smooth the surface out by wet sanding with an orbital sander.  Actually worked quite well.
• There were 2 exhaust manifold studs in there (out of 8).  They came out no problem, but I had to buy a new set of those as well.
• Most of the valve train was new except for the lash adjusters which were shot, so I had to replace those.
• Then I noticed that 3 of the 4 threaded pipe connections on the thermostat housing had been drilled and heli-coiled.  I’m not sure how well that is going to seal.
• The only thing that was nice was the headgasket sealing surfaces.  Then I realized that the reason it must be so nice is because the head was shaved.  After some measuring with the calipers, I found the head to be shaved by 0.020″.  I’m sure glad I have that spare 0.020″ Fel-Pro head shim.  Would have been nice if they put some kind of documentation with the head.

In addition to the crap reman head, I installed ARP head studs so that I can stop buying head bolts.  I am also trying the MP headgasket this time.  I also opted for the FM ported exhaust manifold.  This along with the 2.5″ exhaust system I am planning to get should make the top end pretty nice.   I did weld a Products For Power 2.5″ high-flow cat onto the stock down pipe.  The down pipe is 2-1/4″ at the turbo, but actually necks up to 2-3/8″ after the first bend.  This fit fairly well into the 2.5″ cat without a reducer bushing.  I then adapted the stock exhaust off of my Shadow as a temporary measure until I find a place to do my 2.5″ exhaust.

I also pulled the trans to install a new LUK Turbo III clutch (with a Turbo II disk) I got from FM.  The plan was to reset the preloads on the A520, install new seals, and toss it back in.  Well, as luck would have it, I happened upon someone selling an A568 transaxle here in IL!!!  An hour’s drive and $550 later, I had myself the ultimate of transaxles: the A568!  Thanks Gerry!  He also sold me the cables and shifter.  I ordered a new set of seals for it since the input shaft seal was leaking and I called FM to ask them to send me the other half of that TIII clutch I bought.  I found the shifter knob and boot at a boneyard on a ’92 Shadow with a A543.  During the installation I found that a few mods were required, but nothing major.  I will have a page up about this sometime in the future.  Drop me a line if you’d like the details now.

While I was waiting for parts, I addressed the nasty water leaks in the passenger compartment.  The leaks were causing the insulation and carpeting to shrink and rot.  I completely GUTTED the interior, insulation and all.  This car is noisy enough and I don’t care about 2 or 4 lbs of weight, so I replaced the insulation with heat shield/sound deadening insulation.  I also ordered a new molded carpet from Newark Auto.  It was an OK fit and a mediocre color match.  While it was gutted, I traced all the water leaks by sitting inside during some heavy rain.  Most of the leaks were due to bad gaskets and seals.  One leak was a body caulk issue, which the car may have had all of its life.  I spent a lot of time cutting and gluing the insulation back in, and it feels pretty sound now.  I also bought new weather stripping for the doors and had the headliner and visors reupholstered.  The interior now looks quite respectable, especially since it is all Shadow ES instead of half ES, half CSX.  If everything else holds up (yeah right) I will address the body next year.

Well, I have separated this car from my older cars because I have been adding more and more info about it.  So, I thought it deserved its own page.  I’ve done quite a bit of work since I last updated these pages.

First off, I finally bought new tires and put my original crab (bottle cap) rims back on.  I was using 14×5.5″ rims with 195/70 R14 Firestone 350 tires.  These tires SUCK in every way, shape, and form.  I have had 70 and 75 series tires before, but these are just junk.  The dry traction was lousy: I could light up the tires on 2nd gear with only 12psi of boost and the car plowed really bad.  In light turns the tires liked to screech.  I even got a full alignment: no change.  Wet traction was like driving on slicks–I almost got into countless fender benders, but got lucky.  Take-offs were impossible.  I won’t even talk about winter driving.  The tires still have 1/2 of the tread left.  I just wanted you to know how HORRIBLE these tires were for me.

ANYWAY, I had replaced my speedo pinion gear to compensate for the larger 195/70 R14 tires and I was enjoying the lower RPMs at highway speeds compared to when I was on my 205/50 R15 Gatorbacks.  So, I decided to use the Plus Rule, and got some 205/60 R15s to maintain that ratio.  Sears had a sale on Falken ZIEX high performance tires in my size, so I ordered a set.  I have to say that these tires are GREAT!  I have over 1000 miles on them already, and they seem like they hook up as good as, if not better than the Pirelli 700s on my CSX, and much better than my old Gatorbacks ever did!  Wet traction is also very good, which surprised me given the large tread block on these tires.  I can go full bore in 1st gear and the tires will keep grabbing.  I can feel the control arms “shimmy” has traction switches back and forth between the wheels: time for some polyurethane bushings.  Understeer has been dramatically reduced, but when pushed to the limit, the car will plow like it is supposed to.  The Falken ZIEX are one of the best performance tires you can get on a budget.  I think I will be putting them on the CSX (in 205/50 form) when the time comes.

Is that a plug, or what!  🙂

Another issue I FINALLY resolved with the Shadow is the sagging rear end.  All of the P bodies (also H bodies) I have ever seen (except for Shelbys) seem to get tired rear springs rather quickly.  The frame in front of the rear tires was about 1/4″ lower than the frame behind the front tires.  Rather than replace the springs with new, marginal ones, I opted for some air shocks since I am always hauling stuff around.  I installed a pair of Gabriel HiJackers and the cheap air line kit (about $60 total) and pumped them up to about 40psi (minimum is 25psi).  Now the car sits 1/4″ higher in the rear than in the front and the car just looks “healthier”.  The best part is that the handling has been improved even more!  Now the car tracks through the corners with a very solid feel (like my CSX) and will take corners even harder than before (not as well as the CSX, though), but will still break loose and plow, as it should (in case you have never driven an ’87-’88 CSX, they tend to oversteer when you REALLY push them).  Also, I can haul heavy items in the rear without bottoming out, and I can accelerate hard without aiming for the moon.

With a cleaned IC and my boost back up to 14psi, the ND T2 SMEC, and the improved handling, my Shadow is just a blast to drive again.  Everything on the car works and is functioning well.  There is only one problem: the poor Shadow is suddenly suffering from the infamous American Car Paint Peel Problem.  The paint has held up well all these years.  Suddenly this summer, it’s peeling off the roof, truck lid, tops of the doors, etc in small chunks.  Grrr…  I’m not sure what to do with it, but I probably won’t touch it this year.  If things are still going well, maybe I’ll get it painted next year.

Broke 500 miles on Friday (19th)!  Woo!  The engine is now broken in.  I hooked up the wastegate solenoid around 400 miles and have been enjoying the power.  🙂  The boost likes to creep to 14psi, before the computer pulls it back down to about 11psi.  Luckily, I’m not hitting cutout.  I guess it’s time to play with restrictors again.  I drove the car all the way to work on the tollways and it did just fine, aside from the bumpy ride.  Here is the car as of today:

As if that weren’t enough, Arlie Hart is selling a GLHS in New York to a guy in Chicago.  He agreed to carry the last two panels with him, so I may have them this weekend!

The next major project will be to gut the interior again and try to find the source of my water leak.  The carpeting is getting musty again and it seems to be shrinking.  I’m not sure what to do with it at this point.  I may have to trash it in favor of some new carpeting.  It sure could use it.  The headliner is another issue.  I plan on buying some headliner material and gluing it on this summer as well.

The only other big problem is the suspension.  It definitely needs new shocks and struts, judging by the way it hops all over the place..  I have a lead on some interesting units, otherwise I’ll go with Konis or KYBs.

I had a burning desire to work on the CSX and I had the opportunity last Thursday (the 4th), so I put in some of the parts I had.  I also pulled the valve cover and tried to quiet down the valve train by pumping up the new lifters again.  While I had the cover off, I replaced the fuel pressure regulator with the adjustable unit from Rick Diogo.  I also replaced the spark plugs because they were fouled from running so rich (RN12YC).

After allowing the RTV on the valve cover to cure for a couple days, I started up the engine and adjusted the fuel pressure.  I brought it down to 50psi.  I took it for a spin and it’s running so much better…much more low-end torque.  The plugs looked fine afterwards.  I’m still at reduced boost, so I won’t know for sure for a while.  It was nice to drive it again.

The dumb thing still has a water leak somewhere.  I guess the search will continue.  I also installed some of the interior pieces from Arlie Hart, but I still need to get the two, large rear sail panels from him.  Anyway, it looks much better with the darker trim pieces.

Well, I received the adjustable fuel pressure regulator from Rick Diogo.  It is actually for an ’89 or later turbo, but it will work just fine the and pipe connection opens up the option for a custom fuel setup.  It appears to be a used unit that has been modified.  An aluminum cap with the hose barb and adjustment bolt covers what is probably a cut open, stock regulator.  Better than hacking and gluing with JB Weld, or crushing it in a vise, in my opinion.  🙂  I also received the pressure isolators I ordered for the oil and fuel pressure guages that I will be installing.  They look like they will do the job and I will add specifics on how to get them to the Mini-Mopar Resource Site when I get the chance.  I also updated this page with a picture of the pistons and rods I used on the engine rebuild.  I actually had several pictures of the rebuild, but my nice camera and the roll of film they were on met their demise while I was on vacation in December.  I am annoyed.

Since it cold outside these days and the CSX is buried in a foot of snow right now, I haven’t done much with it.  The old battery also decided that it doesn’t like cold weather and has died.  I don’t want to drive this car through the salty roads of a mid-west winter anyway, so it will stay where it is until spring.  I will then buy a new battery, install the goodies I have been collecting, and hopefully continue the restoration if I can.  I can’t wait to get that ND Performance logic module in there!

My future with this car is becoming uncertain at this point because of certain events going on with my life.  I hope I will be able to keep it after all this work and years of waiting to finally get one.  Keep your fingers crossed for me….
