Hey all-
It's been quite a while since I've been here, but I picked up (and drove 90 min home) a 1982 245 with LH1.0 with an m46 in excellent condition (for Minnesota). It looks like it hasn't really been driven much in quite some time, and certainly has a couple vacuum leaks, but upon getting it back to my house, I realized it has some pretty unique ignition/parts characteristics... I definitely have some initial questions (see below).
My goal on this one at the very least is to get it in excellent running shape and see what kind of mpg I can get out of it as this is supposedly one of the the fuel sipperiest version of a 240, and in the meantime get a good TB project/build thread going as there is just NOT a lot of info out there on these vehicles- even for simple things like finding the correct injector seals and accelerator cable.
Initial questions (see photos below for reference):
Electrical:
1. Harness: It looks like the engine harness (injector wires aside) is in pretty decent shape- it certainly doesn't look like it's biodegrading (and may have been replaced at some point), but the harness from the connector on the firewall to the cabin (perhaps in the cabin), looks like absolute crap as you can see from the photo. There's a rumor that LH1.0 was made with a non-biodegradable harness- is it true?
2. Mystery parts: I have a weird capacitor looking thing near the coil with 1 wire coming out- haven't traced where the wire goes yet, but does anyone know what this part is? How bad does my coil look on a scale of 1-10?
Additionally, there is an odd black box mounted on a valve cover bolt that has a few wires running out, a cap, and 3 female connectors underneath... WTF is it?! And what is the silver box mounted next to the battery?
3. Chrysler Ignition- it SEEMS to be working (hell, it got me home), but it sounds like swapping out the distributor (currently the white Chrysler cap setup) to a Bosch Breakerless is a good idea? Can anyone provide the correct part number for the distributor I need? Additionally, do I just need to track down a rectangular pigtail from Barton ( I imagine there is a round connector on it) and splice it onto my harness, pop the vacuum hose on and BAM, or is there a little more involved (timing, ecm, etc)? Do I keep the Chrysler Black Box with this setup or do I switch it out to... something else? Do I also have an LH box in the pax feet area? It's a bit confusing as to what exactly the box is doing.
4. Setting the Idle- I plan on going through the vacuum system, putting on new hoses, cleaning out the IAC/TB etc, but it looks like the PO already swapped out the AMM to an 002 (I believe LH1.0 typically has an 001, but the 002 is an 'acceptable' swap from what I've read) and likely messed with the adjuster screw... Does anyone have good words of wisdom or a link for setting the idle back to where it needs to be on LH1.0?
5. LH1.0 Misc Part Rarity- It looks like there are more than a few oddball parts on this beast- that vacuum switch on the firewall, coldstart injector, the Chrysler box, a thermal time switch and even the fuel rail and IAC hoses (perhaps the IAC itself)... Should I be keeping an eye out for these things/stocking up? Are any of them especially prone to fail?
6. Is it really true that disconnecting the Black Chrysler box will kill it???
7. Is there an easy way to remove the square types of connectors on the injectors, etc? I used a tiny screwdriver to basically move the paperclip wire out of the connector- it wasn't easy even on a very accessible part.
8. Vacuum diagrams- I have this faint feeling the PO might not have hooked the vacuum hoses up correctly (throttle body has a completely open nipple- no hose in sight) and the diagram under the hood looks to be more of a... guideline. I was hoping the LH 1.0 green book would be more helpful in this area, but it is not... Are there any good guides/sketches out there?
If you can help answer any of these, it would be greatly appreciated and will certainly be going into the build thread. Thanks!
