After having the van inspected I was informed that the following items would have to be fixed before it would pass:
1. ABS light was on
2. Passenger side rocker panel was rusted
3. EGR tube was leaking
4. Exhaust manifold gasket was leaking
It's not like I haven't worked for hours on this van before:
1. Driver side rocker panel
2. Instrument cluster
3. Front left wheel bearing
4. Rear right wheel bearing
5. Transmission oil cooler
6. Transmission issues (EPC solenoid)
7. Transmission issues (Shift solenoid)
So I wasn't surprised that it was going to take a lot more time in the shop. After I got over feeling sorry for myself (well, I'm almost over it) I figured I'd work every evening for about a week out in the shop almost til midnight, but I did get it all fixed and the inspection passed and now I'm driving it again with a renewed "I can do this" and "You ain't getting me down, ya bloody van" attitude.
Difficulty Level (Easy, Medium, Hard, Insane):
Medium
Process:
ABS Light
The ABS light issue was definitely tricky because I had 8 possible points of failure or any combination of multiple points. I could have just paid $75 bucks at the shop to have it scanned but I refuse to pay that much for something that takes less than a minute so I decided to figure it out the hard way. Somehow I "knew" the front left wire harness was faulty. Maybe I just assumed it because that was the issue with my Venture van a few years ago, or maybe it was intuition, a gut-feeling or being let by the Holy Spirit, I dunno. In any case, I ripped out the old wire and patched in a new wire I had saved from when I fixed (and eventually replaced) my H20 steam mop. This fix made it a LOT better. The ABS would only go on every couple of days but would stay off for a considerable amount of time after I turned the van off and then back on.
Unfortunately, this changed after driving to Sussex in a rain storm. The ABS light came back on and so I realized that my previous "fix" wasn't completed yet. I ripped out my trusty old multi meter and soon discovered that the rear left wheel showed 3 mega ohm resistance and was climbing; an indication that the sensor was shot. For reference, all other wheel bearings showed 1.25 kilo ohm resistance which was well within specs.
Down to Marshland auto parts I went to pick up a new wheel bearing ($130 bucks), jacked up the van, removed the tire, unbolted the wheel bearing and pulled it out after fighting with some rust and corrosion.
When I took out the wheel bearing the cable seemed to be not long enough which I found was odd, considering the last time I did it on the other side. So I investigated a bit further and found out that some bozo had accidentally cut the wire to the wheel speed sensor and then just patched it up with some household electrical wire, twisted it together by hand and put some shrink tubing around it. No wonder the ABS light went on in the rain storm...duhhhh!
Anyways, I removed the wire, replaced it with some new wire, put it back on the van with the OLD wheel bearing and haven't heard a peep from the ABS light since. whoohoo! All-in-all that job took me about 5hrs
Rocker Panel
The rocker panel was pretty easy, I've done it 5 times before (twice with my oldsmobile intrigue, twice with my chevy venture van and once with this van): cut off rusty stuff, weld on new stuff, body-fill, sand, primer & paint and slap some asphalt on it to prevent future rusting. Good thing I bought that MIG welder a few years ago; that definitely made the job a lot easier. All-in-all that job took me about 6hrs.
EGR Tube
At first I was hoping I'd be able to remove the EGR tube from the van and weld it back together since that little 12" tube costs almost $200 just for the part. After heating up the rusted nut though (and literally setting the van on fire - good thing I had an extinguisher handy) I realized that I couldn't get it out without actually breaking it all the way off. The EGR tube sits up between the rear exhaust manifold of the engine and the firewall behind the muffler so I only had a small spot to put my hand/arm up there and trying to losen the nut. When I tried that I just bent the snot out of the nut so I ended up breaking off the EGR tube and used an O2 sensor socket to get it out. My hands are still bruised and cut up from that job. Once I had the old tube out I was able to grease up the treads of the replacement tube and put it back in. All-in-all that job took me about 3hrs.
Leaking Exhaust Manifold Gasket
Last year after I had gotten the van inspected the mechanic informed me that he had missed the leaking exhaust manifold gasket and that I would have to make sure to get it done next year. Well, this time around was "next year" so I had no choice but to do it. The mechanic said that at least one of the bolts that holds the exhaust manifold to the engine block was broken and had them quote me almost $1500 bucks for that job. Since that was defnitely not in the budget I resigned myself to the fact that I would have to figure out a way to do it myself. This was by far the most involved job of all issues and I was quite a bit nervous and maybe even a bit insecure because I had never done it. However, remembering that I felt similarly for any other job I had ever done for the first time I psyched myself up to getting at it and giving it a go.
In retrospect it really wasn't all that "magical". Yes, it was technically difficult and frustrating at times but in essence it was a simple matter of taking parts OFF, REPLACING parts, and putting parts back ON. Here's the order of steps I had to take:
Remove air intake tube
Remove air filter & housing
Remove engine torque strut mounts (2)
Remove engine torque strut mount bracket (1)
Remove EGR tube
Remove transmission oil dip stick tube
Remove coolant by-pass tube
Remove exhaust crossover pipe heat shield
Remove exhaust manifold heat shield
Remove exhaust manifold
Extract broken studs (2)
Installation was reverse of removal
All-in-all this part of the job took me about 10hrs from start to finish

| The full view of the cable. Of course they had put shrink tubing around their "fix" so it actually wasn't quite that apparent on the van |
 |
| I bought some cable ends (silver) for about $5 bucks (for ten cable ends) to go inside of the original plug |
