    To fix or not?

    122 (3).jpg
    125 (3).jpg

    Back in July I picked the wrong Cadillac, a 1992 Canyon Yellow w Pearl Cadillac STS with that peanut butter colored interior. Beautiful car it really is but when I saw it and looked it over I had decided against buying it. Unfortunately my wife was talking to the lady and pretty much closing the deal(she thought me looking over the car so well was because I liked it lol). Well after doing plugs, wires, distributor, o2 sensors, ECM, upgraded injectors, new fuel rail harness, distributor harness, the car still had this weird miss. No biggie I just drove it gas mileage was normal 15/24 and it drove like a dream.

    Had some concerns from day one about head gasket but hey its the ironhorse 4.9, well from July to December it never got over 185 degrees and has had minor issues although one very random one drives me insane. Well I have now confirmed the head gasket is bad, and to boot the transmission is bad, has the loud clunking sound if you rev it up to 3k rpm and when it idles back down it makes the sound. Read here that its the sprag. And when I first start the car up every evening at work it won't move forward in drive unless I rev it up in nuetral a little bit first. Never in the morning or any other time just at work which is very odd.

    The question is should I keep or sell it? I can do the head gaskets in a day if I decide not to take the heads to the machine shop, I could swap motor and tranny in a weekend with ease. The labor for me is free it's my time. Head Gasket Set and oil/filter, coolant runs me about $200.00 or less I have a commercial account. But finding a transmission will end up costing me about 400-500. Then I would still need filter, pan gasket, fluid and seals. Maybe another 100 bucks there or less.

    Another option and I know it sounds bad but I have been scammed more than my share of times is to throw some head gasket sealant in there and sell her like she is. Really pretty car people ask to buy it all the time. And since its leraking exhaust in the coolant I am skeptic that crap would even work.

    Other option is to post it on craigslist with bad head gasket and see if I get any hits. I just cant lose my ass on this car I payed 2k plus all the work and 2 brand new 20 inch tires that cost me 381.00. And please honest opinions no need to try and not hurt my feelings after all it is just a car.

    Sounds like you really like the car and can do the work yourself, so I would do it.

    Re: To fix or not?

    I agree. But you did not post the mileage.
    Anyway, happy-wife, Happy-Life !!

    You are fortunate to have the skills to do the work yourself. You are into it around under $3K after you repair it all yourself. Can you buy a nicer car of any other brand for that much?
    So look at the perspective of short and long term cost to use benefit considering any 'next shoe to drop' scenario.

    Me on the other hand, would opt to take a cross country trip until she burned, then junk it.
    Because I would have to submit myself to $$ mechanics $$.... (caveat- generalized sentiment- I know many on this forum are decent folks)

    92 sevilles are pretty rare in the want ads. So many 95, 98, 99 cars. Even though the body changed a bit and motors evolved. I don't even look at posts concerning 4.9 motor work. I know changing the water pump is a pain. And head gaskets seem much more durable than the NS motors.

    Re: To fix or not?

    Well it has 128k miles not too bad at all for its age. As you can see it is in really nice shape. I looked all over the net for cars last night and don't see anything as nice for the money I need to put in this. So I think I am going to fix it. However I will just do head gaskets for now and put the transmission money to the side, my brothers boss thinks he can rebuild mine fairly easy. So that may be an option down the road. It shifts and drives great just the sound(which I don't ever rev it up lol) and the weird issue where it doesn't move immediately when I get off work.

    As far as working on the 4.9 I find it to be an easy motor to work on, even the so called dreaded water pump. I do them in an hour or less. The timing cover to me is the worst thing about the 4.9 Well in a few weekends I will tackle the head gaskets I will let yall know how it goes.

    that's what I suggested to customers facing big repair bills -

    consider a few things -

    1- do you still like the car -

    2 - what's it worth in present condition -

    3 - how much to put it back into good shape -

    4 - what else is available for the total $$$ if you add #2 and #3 together -

    I'm on my 3 rd. 4.9 now and the only weak point they seem to have is the water pump,overall they cost less to maintain than the NS, I have also owned a 97 sts that
    was a money pit, and I maintain my vehicles very well, my 92 eldo. has 165,000 miles on it and still runs great.
