I made some more progress this evening, though I did not take any pictures as I didnt figure it would be all that exciting .
Yesterday I scored a slew of used parts from a local 240 owner. I picked up a near mint piggy lip, a clean primed fender, some windshield sprayers, a unbroken hood hinge, and a spare set of injectors. I installed everything except the fender and injectors. The fender will need to be painted, and I just grabbed the injectors for good measure.
I also replaced the front pads and rotors, as the rusty discs were causing a pretty nasty pulsation. The car now has all new brakes.
The bulk of the resurrection is nearing completion. I hope to take the car to the upcoming Lake Superior Performance Rally. It is about a 300 mile drive one way, and the car will need to be in top shape by the time I leave on Thursday.
This leaves two issues to be covered, the first being very simple, the second much more complicated.
Both outer tie rod ends are showing some wear, and I would feel safer if they were tight for the trip, I hope to pick up some replacements tomorrow.
The brings me to my problem. The car seems to be consuming an excessive amount of fuel. The first tank of gas only lasted about 150 miles, and I recorded about 15 miles per gallon, 60% highway miles. This seems to be out of the norm so Ive done a few things to reconcile that.
I started by replacing the fuel and air filter, I had meant to anyway. I pulled the spark plugs, planning to replace them, but discovered they are in perfect condition, with no fuel soaking. I regapped them and put them back in. The wires also seem very new, and they are showing no signs of carbon tracking.
With all of that done, the engine does seem to idle and drive better, though there is still a slight burble to the idle. Ive spent little time with the SOHC engines, so this may be normal.
Another thing I think may be effecting mpgs is the fuel quality. When I got the car it had about 1/4 tank of gas, and the owner said it sat for almost a year. With the first tank I added some fuel injector cleaner to help clean out any buildup. When I filled up this evening I added a bottle of Heat to absorb any remaining water.
If all of this has no effect on the issue, my next step is pulling the injectors to clean out the ports a little, as well as cleaning the throttle body and MAFs.
