weekly update
Well, I proved my devotion to Dora this week because it was bitterly cold outside with plenty of piercing wind. I dug out that jumpsuit I used last winter and started prepping for next week's trip down to California for Christmas.
We had our club Christmas party and I we ventured out on snowy/icy covered roads. I wanted to see how Dora would do and I was suprised to find it pretty scary to drive. It turned out being toed in too much and was causing it to dart side to side as I lost and regained traction. Having the locker in front only accentuated the problem and I resolved to get that straightened out before the trip. I'm starting to wonder if I've got any bent parts. With the help of another friend we got it dialed back in and it tracks better down the road. It still has some sway and I attribute that to the position of the front shocks, fat tires, and no sway bar. I think I'll work on getting the sway bar put back in due to my pickiness with it's handling on the road.
My LED bulbs came in and I figured out the wiring. Now all the LEDS (including the additional gauges) dim with the factory dimmer. I also saw this little cigarrette lighter flashlight when I ordered my bulbs and thought that was a good idea so I added it to the order. I don't smoke so that outlet can go to some use now.
I pushed it in all the way at first and had a hard time getting it back out since the outlet is recessed. My wife got it out and now I push it in just far enough for the light to come in. It glows red when it's charging and isn't an issue at night when driving.
I rotated the tires and checked the spacers with again nothing loose. While I had the tires off I siped the center lugs with my grooving iron.
I've siped both of these tires. I then turned the blade over and have grooved the right side tire in this pic. I just grooved the center lugs with angle and horizontal lines. It looks like what they should have come like from the factory.
Once I got that done I worked on the signal line from my intake manifold to the AFC diaphragm (fuel compensator when it sees more boost). I think the fittings were bottoming out and not putting enough force on the rubber washers to make a seal so I got some parts to space the fitting out and give me more clamping force on the sealing washers.
I tried a couple different things and decided on stretching a rubber o-ring to go behind the sealing washers.
Hooked it back up and took it for a test drive. No difference and continued gauge flutter so I went back to the drawing board. I took it off and this section alone has 8 possible leak points.
I found myself at the local hardware store with a new plan to replace that section. I came home with some more parts to try out.
I could not find a hose barb with the same threads as the fitting to the left of the copper tubing so I decided on using it to make a hose connection. I already had the hose (nice silicon inner and rubber outer re-enforced hose) and got parts to hook it up. I plugged the original hole in the intake plate and opened up a hole on the side. I put the special fitting back in the AFC housing.
Then I hooked up my hose. I double clamped the part that slid over the copper tube since it didn't have any barbs. The hose fit tightly on the copper tubbing to begin with.
It was about lunch time yesterday on my last day off and I decided to take the plunge and make an intake horn. This was significant because I was planning on using the metal tube I made to connect it to the current intake so I'd not be able to easily go back. I traced and cut/drilled a base plate earlier along with picking up another section of straight 2 1/2" exhaust so I had some parts ready. Here is some mock up of positioning to make sure I had access to what I needed along with not hitting the hood. I'm making a new intake because the current one necks down and rubs the hood. I decided on 2 1/2" because the rest of the system is that size, I have parts to work with, and it is bigger than the neck down on the current intake horn. I suppose I could go with 3" and maybe that will be worth while down the road.
Once I got it where I wanted I welded it up and did a quick visual check for holes. I was running out of time and kept having set-backs so I'll have to go back through and finish it off but for now I slapped it together.
Visually I like how it lays in the the engine bay. I'll have some holes to patch since boost is still fluttering. I've detuned the pump just a little to gain some economy for the trip and even with that boost builds quicker so I think the new intake is going to work out well. I'll update once I get that cleaned up.
To finish off preparation I checked/topped off all fluids and it looks like all I need to do is fill it up and hit the road.
