(Feel free to point me to existing threads. I've searched, but haven't found what I'm looking for.)
I have several B230s, and have refreshed about half a dozen now around the 200k mile mark.
I want to do the same thing to my new '78 245 with a B21 (center, below). This is my first B21 and first K-jet. I know what to do with the parts that are the same as my later 240s, but I'm not sure about everything. I think this car was completely OEM, originally from California. I just want to keep it stock while making simple improvements to keep it on the road a while.
The story with this car is that it was running "fine" until the battery cables shorted out and started a small fire while the previous owner was driving it. He parked it after that, and I bought it a while later. As far as I can tell, it didn't damage anything (other than the old battery cables). But while it was parked, the pack rats moved in and chewed wires and two injector lines. They also packed sticks and debris into every nook and cranny, so I've been opening everything up to clean it.
My first priority was to replace the battery cables, repair all the wiring, and replace the two injector lines that got eaten. I also decided to delete the old York AC system. The engine is really dirty, and I like clean engines, so I decided to pull the K-jet and intake manifold and clean things up while I'm waiting on parts.
I didn't realize that these old engines had no oil trap in the block, only the vent in the valve cover. Is there anything else under here that I should take care of while it's accessible? I plan to change the heater hoses, all vacuum lines, and engine mounts at a minimum.
The K-jet air flow sensor and fuel distributor are really dirty. How much can/should I disassemble things, and what else should I refresh on this while I have it all out?
Air flow sensor: 0 438 120 078
Fuel distributor: 0 438 100 032
(You can see the pack rat art in the bottom right corner.)
Should I use all new copper washers when putting the K-jet back together? If so, is there an easy list with part numbers and sizes that I need? I've been looking at schematics, but I can't find a clear image and list.
I plan to change out all rubber components in the engine compartment. What can I delete? I was planning to eliminate the charcoal filter to clean up the engine compartment, but maybe that's a dumb idea. Should I just replace the OEM valve cover flame trap with like components, or is there an upgrade that is recommended?
Anything else?
Thanks,
Jason
