    Default Need advice on 1993 Suburban

    Hello all,

    I've been fortunate (I think) to be able to get a 1993 suburban essentially free (trading for some computer services).

    It has 350k miles on it, and is on it's 3rd tranny. I'm not positive yet if it's original from engine point of view. In addition to that, it's been "sitting" for 3 years.

    From a body and interior aspect i'd give it a 7 to 8 out of 10...it's really nice for it's age.

    Don't know how it is mechanically...

    I'm hoping for advice...I really like it and would like to make it work.

    Some options I've considered:
    1) "Bare minimum" - have it towed to a mechanic and have him do the least he can to get it running and driving. From here, fix what needs fixing as needed.
    2) "All out" - Go ahead and get the engine overhauled and/or replaced (I'm worried about getting ripped off here)

    I think the tranny will likely be ok...but engine and "rubber stuff" will need some love.

    What do you all think I should do?

    How mechanically inclined are you? There are lots of things you can do on your own if your willing to do some of the work.

    I would start with the basics, pull the air filter, check the plugs, change the oil, drain the fuel and replace, check all the fluids. Replace any fluids as needed. Maybe a new battery. Theres always an endless list that you can come up with to work on. Start with what you are able to do on your own, if you are interested in doing a little of the work.

    If you are uncertain of the work, it doesn't hurt to bring it somewhere and get their opinion on what it would take to get running again.

    Good luck!!!

    I'd consider myself "adventurous" in the shadetree mechanic space...willing to tackle anything given the right tools, time, and service manual.

    I'm missing the time and service manual though...and potentially the right tools

    Where I'm leaning now is to have it towed to a mechanic to perform the things you listed and see if I lucked out and will be able to get some free time for a while, while I research longer-term options...

    in the long run you might want to just swap out with a waranteed crate engine
    and not have the money hole to worry about...

    Since its free its certainly worth getting it checked out, have your mechanic (or you if you can) do a compression check first, that will let you know if the engine is ok or not.

    now i could be wrong on this.. but i think c is 2x4 and k is 4x4


    if the engine will not turn at all manually (you should get SOME movement just pulling on the belt in the right direction) then pull all the plugs and add some oil to each cylinder.
    ( however much you want really, but you only need 1/8 of a cup just enough to cover the cylinder head and lube the walls,use a light oil or even something like liquid wrench ) wait 2 hours for it to soak in then use a breaker bar on the flywheel bolt to turn the engine over a few times. the oil will squirt out.
    if its really really hard to turn over then the motor may be junk even if you get it to run
    after it turns pretty easy manually you can use the starter..
    i have never had to do this in anything but a old (and i mean OLD) lawnmower
    the valves have to be open so the cylinders can corrode
    after you can use the starter all the oil should be out of the cylinders

    a compression test can be great help if telling cylinder condition
    do a compression check after it turns. if you have low compression add oil to seal the rings and see if it goes up.

    to get rid of the bad gas ( its a 40 gal (150L) tank)
    pull off the two gas lines from the back of the throttle body (cant remember which one is return) and put a couple of rubber hoses and clamps (i used old garden hose) on the lines and run them to a gerry can.
    turn the ignition on and the fuel pump will drain the tank for you.

    take the sparkplugs out and then either crank it , or suck the oil out with a small oil change pump on each cylinder !!!
