I have been offered a 94 Buick Skylark 3100 for 100 bucks. The owner parked it about 2 years ago when he found coolent in the oil. He is insisting that it has to have a bad head gasket, just because the oil is contaminated with coolent. I told him a few times that it's probly just the LIM gaskets, but he still thinks it needs new HG's. Now he just want's the car gone. I have done the LIM replacement before on my wifes 3100 GA-GT so I know I can do it my self. But I'm a little worried that the coolent sitting in the engine for that long has caused damage to the bearings. The water should of settled to the bottom of the oil pan, but depending on how much water is sitting in the pan, it could submurge the crank.?.

Should I take my chances and buy the car? I really dont want to do a full engine replacment, but I'm fine with the LIM gasket replacment.

The body is in "OK" condition, they let a ball joint go so the wheel messed up the fender. But the ball joint has since been fixed. I think it has a little over 100k. I would'nt be surprised if the battery is bad and tires are flat and tabs exspired.

You could just drain the oil and temporarily fill it with cheap oil and start the engine for a minute and see if it has a deathly rod knock to it, or other telltale signs of impending failure. If not then just do the LIM gasket replacement and either keep it or sell it and pocket the money. Would he let you change the oil and start it for a little bit? The issue that I see is that ethylene glycol is corrosive to engine bearings, so without starting it to see if they melted, there is no telling what condition they are in. ...The damage based on the fender, the battery and the tires are something you will need to take into aco****. They seem to go for $1,000-$2,000 around here when they are in decent condition, maybe a little bit less with the body damage.

I did think about draining the oil on the spot and replacing it. But I rememer when the LIM gaskets went bad on my Grand am it ran poorly, I'm guessing from a vaccume leak cause from the bad gasket. Do you think if there is a problem with a bearing, that it would show up right away? Or would it take a few miles of use to get it to show?

I'm also from Minnesota, so yeah I was thinking it would be worth about $1500 in running condition. So I'm looking at $100 for the car, ~$45 towing, ~$35 new tabs and ~$40 for new gaskets and fluids, plus if it need's other parts like a fresh battery. If the engine is'nt damaged from the coolent sitting, it's worth it. If the engine is trashed, or really does have a bad HG or cracked head, I dont want to take it on. :(

Any changes in the auto tranny from 94 to 95?

Usually the damage has been apparent by excessive noise right away, or will be normal and slowly get worse over time.

It sounds like you have already come up with the answer to the question you are asking. There is definetly going to be less life to the engine because the driver of the car obviously drove it for at least a little while before he discovered that there was coolant ingress. Isn't the head gasket replaced when the LIM gasket is? I thought it was part of the gasket kit. You could save money on the battery by borrowing one from another car if you have an extra. ...The performance might suck if the gasket isn't making a good seal but when you start it you would at least know whether its trashed off the bat or if it has hope. Personally if I were to do this, I would borrow the battery from my car, give it an oil change before starting it, and put the battery in and start the car, if it doesn't knock horribly, I would see if I could fill the tires with air, and use the spare tire if I needed to. When I got the LIM gasket fixed I would personally just sell the car right away.
The reasons for that is:
1. New gaskets have proven to not be a permanent cure.
2. I don't like skylarks.
3. I'd only do this to get $500-$1,000 in my pocket.

Basically if I were to do it I would need to make sure that at least 3 tires could be filled so that I could drive it, unless the grand am spare fits okay, then 2 tires. I would buy a $30 walmart battery, they seem to last at least a few years and they are the price of a tank of gas at todays prices. I would also probably tow it with a jerk strap myself. ...I wouldn't worry about tabs until the car is running. Labor/Time is all about how much it is worth it to you.

If you plan on the car being your sole means of transportation I wouldn't do it. If you wanted to have a beater or just a car to drive until it dies, then go for it.

Keep in mind, car selling sites like Carsoup have sections for Repairables and Salvage which people seem to get money off of cars that are wrecked or have bad engines or transmissions, so the risk might not be too bad.

Nope.

I will do what I can to get it running on the spot before I buy it. Then decide. I will probly sell it right away, but it supose to have working A/C so there is a chance I'll use it, and take my chances on the engine. I guess the worst case is I'll have to grab a junk yard 3100.
