Thanks for the replies, everyone.
Looked at the ’87 Eagle Limited today. As with any 24 year-old car, there’s the good and the bad. The good: the body appears sound. The engine mechanically sounded good, with no knocking or valve clatter. It started right up and ran fairly well, with a slightly uneven idle. Through the oil filler, I could see a good amount of oil being pumped up to the rocker arms. The oil itself was passably clean and didn’t smell burnt. The tires looked good. I didn’t do a detailed undercarriage inspection (it was raining) but nothing appeared amiss.
In the neither good nor bad category, a full set of aftermarket gauges (water temp, oil pressure, amps, vacuum, tach) are installed, plus a good stereo receiver (stock speakers, though).
The “concerns”: we weren’t able to really drive it, only back and forth in a parking lot. The transmission fluid, antifreeze and power steering fluid were all low, with the transmission about a full quart low (it barely touched the bottom of the dipstick, less than ½”). It’s not a big deal to replenish fluids, but my question is, why are the low? Are they leaking, or being burnt off? Starting off from a stop, it seemed a little sluggish; possibly being one quart low in the transmission could explain this, but it’s a concern. When I stepped on it a little harder, it took off fine.
The current owner has de-smogged this engine, with a Ford carburetor and an aftermarket air filter and vented oil filler cap installed. However, the PCV is incorrectly installed, with no vacuum felt through the PCV valve. I’m sure this can be corrected, but concerned about fixing someone else’s work. When switching to 4WD, a hiss (vacuum leak) is heard, which did not go away. There was no way to test if the 4WD was really working. I’m not sure how the front seats adjust; would a Limited not have power seats? If so, the power seat adjuster was missing from the driver’s seat (I don’t know if the owner has it). Some of the power door locks don’t work. The front carpeting is missing.
I think our next step is to go back again with a quart of transmission fluid and see if that improves the transmission’s response. What kind of transmission fluid do these transmissions use? I believe the seller is open to negotiation, but sometimes even “free” can be expensive. I might be inclined to replace the carburetor with a rebuilt stock unit, so I can use the stock air filter and get the PCV correctly reinstalled. Regarding the 4WD switch, which is obviously leaking, is this repairable? If not, are replacements available? Has anyone de-smogged one of these? It may not be legal to even ask this, but can anyone provide a guide for what should and should not be removed? Again, I’d rather start with a whole, unmolested car, but since de-smogging was started, I just want to make this one run well and get good gas mileage. I’m a big believer in PVC systems, so I’ll definitely reinstall that.
Thank you.
