    Hey everyone!

    I just came in to possession of a decent 87 4runner 4x4, 350k miles on the dash. It has sat in a field for a large part of 20-30 years.

    4AD0B162-8726-4F06-BB71-98A8736CB763.jpg E49240F7-3F49-420E-A465-7D11F1E406DF.jpg DAB90A60-454E-4740-BABD-034C759CFA03.jpg
    The good…
    The prior owner got the engine running, but that’s about it. New gas tank, fuel pump, battery, supposedly master cylinder.

    The bad…
    It will no hold a charge. Has to be jumped pretty much every time it starts. Has no brakes. Brakes go to the floor and have to use e brake to stop it from going anywhere.

    Plans are to start with changing the alternator this weekend so I can at least keep it mobile. Then work on the brakes to get it more Street able. Oil is all around the head gasket so I imagine that won’t be far behind. There’s rust everywhere on body panels, some places worse than other.

    Does anyone have any suggestions on what would be wise to fix after what I have outlined?

    I like to think I saved it from being reclaimed by nature!

    I'd do all new brakes everywhere, all fluids, check chassis/suspension for rot, and inspect for reptiles.

    As someone who has gone through a few car restos...here's my advice.

    1. Do NOT disassemble the entire car all at once. You will never get it back together. NEVER. Pick your battles.

    2. Verify the extent of the rust. You didn't supply any good pictures to do that but from what little I can see, I don't see rust as an issue yet. If the rust has gotten into and damaged the frame then you need to make a decision whether to fix it or not. Body work is very very expensive and endless on a rust bucket. The mechanicals come a FAR second place to body issues. Do not spend money on anything else until the body is figured out.

    3. Put a plan together and try to stick with it.

    4. DO the FULL job. For example. If you're going to redo the front brakes, disassemble ALL parts, clean, inspect and replace what's worn. Or you'll be right back working on it again because something broke or started leaking. You will pull things apart and be amazed at what you find. "How in heck is that still working?" was uttered more than once.



    Why do you think the alternator is bad? Holding a charge has nothing to do with the alternator. Supplying a charge has everything to do with the alternator. Which is it?

    Sand that roof down and primer it before it gets any worse.

    If I leave the battery hooked up, it will go dead. Lead me to believe a bad alternator since a bad alternator will drain the battery over time.

    also…

    Never seen a bad alt do that. You have a parasitic drain somewhere else.

    Update: Drove it to the hobby shop, was running really rich, smelled of gas, was backfiring in the parking lot and died shortly after. After rolling it into the shop, changed the alternator and all the belts. Would crank but not turn over. This weekend, plan on doing the spark plugs and wires, distributor cap, and replacing all the old vacuum hoses.
